The best siphon feed spray gun for larger paint batches is the Throohills HVLP Siphon Feed Spray Gun Set, with a 1000cc cup and 3 nozzle sizes. Choose Dynastus for oil-based or latex paint, or Astro Pneumatic for a 1.8mm primer gun.

Siphon feed guns place the paint cup below the gun, which makes them useful when you want a larger reservoir for a long spray session. The right choice still depends on nozzle size, coating thickness, compressor output and how often you want to stop and refill.

For the wider category, see our guide to the best paint spray gun. If you are comparing cup positions, our roundups of the best gravity feed HVLP spray gun and best HVLP spray gun kit cover the main alternatives.

How we chose the best siphon feed spray gun picks

The best siphon feed spray gun should match the paint, job size and available air supply. We compared cup capacity, nozzle size, controls, included setup items and the stated use for each product.

A larger cup reduces refill stops, but it also adds paint weight below the gun. A 1000cc or 1000ml cup suits longer passes, while a smaller cup can be easier to manage for detail work.

Nozzle size also changes the decision. The Throohills set covers 1.4, 1.7 and 2.0mm, while Dynastus uses 2.5mm and ENDOZER uses 1.8mm.

The larger 2.5mm opening is aimed at thicker oil-based or latex paint, while the smaller options offer more control for other coatings.

Our score weighs specs, features and buyer feedback against what you're shopping for. We did not treat every product as a siphon gun because Hotorda is gravity feed, VONFORN is AC powered, and Milton is a spray-cleaning blow gun.

Best siphon feed spray gun reviews

The Throohills set leads because it offers the most flexible nozzle setup with a full-size 1000cc cup. The other products are better when you need one specific nozzle, a different power source or a tool for cleanup.

Throohills HVLP Siphon Feed Spray Gun Set: Best for nozzle flexibility

9.7/10Our score

• 1.4, 1.7 and 2.0mm stainless steel nozzles
• 1000cc aluminum cup
• Brass airflow cap
• 6 paint strainers

Three nozzle sizes and a 1000cc cup give this set the broadest setup range in the roundup. It suits buyers who want one siphon gun for automotive, furniture, wall and craft work.

See it on Amazon

Pros

• Three nozzle sizes
• 1000cc cup
• Regulator and strainers included

Cons

• The largest set here
• Needs an air compressor

The Throohills HVLP Siphon Feed Spray Gun Set is the best all-around choice when one gun needs to cover several coating types and project sizes. It includes 1.4, 1.7 and 2.0mm stainless steel nozzles, so you can change the opening instead of using one fixed setup.

Its 1000cc aluminum cup supports larger paint batches and longer spray sessions. The set also includes an air regulator with pressure gauge, 6 paint strainers, a wrench and cleaning kit.

That regulator matters in daily use because it lets you set and check air pressure at the gun. The strainers help keep lumps and debris out of the cup before they can reach the nozzle.

The brass airflow cap has a 360-degree adjustable nozzle direction. Throohills describes it for basecoats, clearcoats and other high viscosity coatings, along with automotive painting, furniture, walls, plastics and craft work.

For set up, match the nozzle to the coating first, strain the paint, then test the pattern on scrap material. Clean the gun and cup right after use so dried paint does not block the passages.

This is the strongest pick if you value setup range. The trade-off is that you still need an air compressor and must prepare each paint correctly for the nozzle you choose.

2

Hotorda HVLP Air Gravity Spray Gun Set: Best for mixed spray tasks

9.6/10Our score

• 0.8mm and 1.4mm spray guns
• 600ml and 125ml cups
• Locking air pressure regulator
• Blue carrying box

This is a gravity-feed set rather than a siphon-feed gun, but its 2 spray guns and 2 cup sizes make it useful when small detail work and larger surfaces share one project.

See it on Amazon

Pros

• Two guns
• Two cup sizes
• Cleaning kit included

Cons

• Not a bottom-cup siphon gun
• Smaller main cup than the 1000cc picks

The Hotorda HVLP Air Gravity Spray Gun Set is not a siphon feed gun, but it belongs in this comparison because it solves the smaller-batch problems that can make a bottom-cup gun inconvenient. It includes a 0.8mm gun with a 125ml cup and a 1.4mm gun with a 600ml cup.

The two cup sizes suit detail work and broader surfaces. The set also includes a locking air pressure regulator, cleaning brush kit, 2 spanners and a blue carrying box.

Hotorda lists a maximum pressure of 70 PSI. Its gravity-feed layout can reduce leftover material in the storage cup, but the smaller cups are less suited to a long, uninterrupted spray session.

Choose this set if one project includes both small detail areas and larger surfaces. Pick a true siphon feed gun instead if your main goal is a large bottom cup.

For a separate tank-fed setup, compare pressure-feed paint guns.

3

Throohills Siphon Feed Spray Gun for Piant: Best for a simple large cup

9.5/10Our score

• 1.8mm stainless steel nozzle
• 1000cc paint cup
• Brass airflow cap
• 6 paint strainers

The single 1.8mm nozzle keeps the setup straightforward while the 1000cc cup supports larger painting sessions. It suits buyers who do not need several nozzle sizes.

See it on Amazon

Pros

• 1000cc cup
• 1.8mm nozzle
• Strainers and cleaning kit included

Cons

• Only one nozzle size
• Paint spelling in the product name is unusual

The Throohills Siphon Feed Spray Gun for Piant keeps the setup simple with one 1.8mm stainless steel nozzle and a 1000cc paint cup. It is a good fit when you want a full-size cup but do not need the extra nozzle sizes in the larger Throohills set.

The brass airflow cap supports 360-degree nozzle direction adjustment. That can help you aim the fan for edges and corners without twisting the whole gun.

The package includes 6 paint strainers, a wrench and cleaning kit. Straining paint before it goes in the cup is a simple step that helps protect the nozzle during a long session.

Throohills describes this HVLP gun for basecoats, clearcoats and high viscosity coatings, with uses that include cars, furniture, walls, art, models and ceramic resin.

For care, empty and flush the paint path after each use and brush residue from the nozzle. Let the parts dry before storage so paint does not sit inside the gun between jobs.

Its main trade-off is fixed nozzle choice. If your projects vary widely, the 1.4, 1.7 and 2.0mm set gives you more room to adjust.

4

VONFORN Paint Sprayer: Best for corded DIY spraying

9.3/10Our score

• 700W power
• 1.0, 1.5, 2.0 and 3.0mm nozzles
• 3 spray patterns
• 1200ml tank

This is an AC handheld paint sprayer, not an air-compressor siphon gun. Its 1200ml tank and 4 nozzle sizes make it a practical alternative for fences, walls, furniture and doors.

See it on Amazon

Pros

• Largest tank here
• 4 nozzle sizes
• 3 spray patterns

Cons

• Not compressor powered
• Plastic construction

The VONFORN Paint Sprayer is the best alternative when you want a corded handheld sprayer instead of an air-compressor siphon gun. Its 700W motor, 1200ml tank and 4 nozzles cover furniture, fences, walls, doors and garden sets.

The nozzle sizes are 1.0, 1.5, 2.0 and 3.0mm. Three spray patterns, horizontal, vertical and circular, let you change the spray direction for different surfaces.

A larger tank means fewer refills on fences and walls, but it also means more weight in your hands. The smaller nozzles suit more controlled work, while the larger nozzles move more paint on broad surfaces.

VONFORN includes 5 paint filters, a viscosity cup, cleaning needle, cleaning brush, dust blowing joint, cleaning connector, pot lid and user manual. The dust blowing joint can clear loose dust before you spray, and the cleaning connector is designed to flush residual paint from the tube.

For set up, test the paint on cardboard first and cover nearby surfaces. The flow control knob lets you fine tune paint output, but small changes are easier to judge.

Choose this model if you do not want to size an air compressor for a siphon gun. It is not the right match if your workflow specifically requires an air-powered bottom-cup spray gun.

5

Milton: Best for liquid cleanup

9.1/10Our score

• 14 SCFM at 100 PSI
• 150 PSI maximum working pressure
• 1/4 inch NPT air inlet
• Diecast zinc construction

Milton is a siphon spray-cleaning blow gun made for liquids, not a dedicated paint gun. It fits buyers who need to spray cleaning or lubricating liquids and blow away messes.

See it on Amazon

Pros

• 150 PSI maximum
• Liquid spraying and cleaning use
• Compact 1.6 oz body

Cons

• Not a paint spray gun
• Hand-powered classification in the product data

Milton is a different tool from the paint guns above. The S-156 is a siphon spray-cleaning blow gun for liquids, with a 1/4 inch NPT air inlet, 14 SCFM at 100 PSI and a maximum working pressure of 150 PSI.

It is designed for cleaning grease from engines and garage bays, spraying plants and flowers, lubricating parts and rust-proofing tools or machinery. Its diecast zinc body weighs 1.6 oz, so it is easy to hold for short cleaning passes.

Those air flow and pressure figures matter when you compare it with a paint gun. A paint gun is tuned for a controlled fan pattern, while this blow gun is meant to move liquid and air with more force for cleaning and coating tasks.

For set up, connect the 1/4 inch NPT inlet to your air supply and use the liquid container suited to the job. Keep pressure within the stated maximum and rinse or flush the gun after use with the liquid you sprayed.

Care is simple because the body is diecast zinc, but paint should not be left inside. Wipe the outside and store the gun dry so the inlet and internal parts stay clean.

This pick makes sense beside a spray gun when cleanup and liquid application are part of your workshop routine. It does not replace a paint gun for controlled coating application.

6

Dynastus 33 oz Siphon Feed Spray Gun: Best for oil-based and latex paint

9.0/10Our score

• 2.5mm nozzle
• 1000ml paint cup
• Separate fluid and fan controls
• Filtering and cleaning kits

Dynastus directly targets oil-based and latex paints for medium to large jobs. The 2.5mm nozzle and separate fluid and fan controls suit thicker coatings when your compressor meets its stated requirement.

See it on Amazon

Pros

• 1000ml cup
• 2.5mm nozzle
• Filter funnel included

Cons

• Requires at least 5.0 SCFM at 40 PSI
• Less suited to fine detail work

The Dynastus 33 oz Siphon Feed Spray Gun is the strongest pick for oil-based or latex paint. Its 2.5mm nozzle and 1000ml paint cup suit medium to large painting jobs in automotive, home and furniture applications.

Separate fluid and fan controls let you adjust the pattern and paint output independently. That helps when a surface needs a wider fan but the paint flow still needs to stay controlled.

Dynastus says the gun requires an air compressor that can deliver at least 5.0 SCFM at 40 PSI. Check that your compressor can meet that need before you plan a large job, or the spray pattern may suffer.

The package includes a filter funnel, extra spanner, wire brush, handle toothbrush, quick coupler plug and cleaning kits. Filtering matters because dried paint or other debris can clog internal passages.

For set up, strain the paint, fill the cup, then test the fan on scrap material. For care, clean the gun right after use because thicker paints can harden quickly in the nozzle and passages.

Choose Dynastus for thicker paint and larger surfaces. A 2.5mm nozzle is less natural for fine detail than the smaller nozzle options in this roundup.

7

AutoViteX 34 Ounce Siphon Feed Spray Gun: Best for adjustable automotive work

8.7/10Our score

• 2.0mm nozzle
• 1000ml aluminum cup
• Adjustable spray pattern and fluid control
• Brass 7-hole airflow cap

AutoViteX combines a 2.0mm nozzle with controls for spray pattern, fluid and air pressure. It suits automotive refinishing, furniture, walls and craft work where adjustment matters.

See it on Amazon

Pros

• 1000ml cup
• 2.0mm nozzle
• Adjustable controls

Cons

• Only one nozzle included
• The included-components field names only the nozzle

The AutoViteX 34 Ounce Siphon Feed Spray Gun suits buyers who want a full-size cup with adjustable spray controls. It uses a 2.0mm nozzle, 1000ml aluminum cup and brass 7-hole airflow cap.

The gun controls spray pattern, fluid flow and air pressure. Adjusting one control at a time makes it easier to see how the fan and paint output change on a test surface.

AutoViteX gives a suggested compressor setting of 50–70 PSI. It describes the gun for waterborne and solventborne paints, primers, varnishes, enamels and stains of all viscosities.

The stated uses include automotive repair, furniture refinishing, wall painting, art projects and crafts such as fabrics and ceramics. A 2.0mm nozzle sits in the middle range for general work, so it suits many coatings without being aimed only at fine detail.

Stir paint thoroughly before use and clean the gun immediately after each session to prevent clogs. The filter helps catch impurities before they reach the nozzle, and the aluminum cup seals tightly for spraying.

Pick AutoViteX when adjustment matters more than having several nozzle sizes. Its product data names the nozzle as the included component, so confirm the complete package before ordering if extra accessories matter to you.

8

ENDOZER Professional Siphon Feed Spray Gun: Best for lightweight finishing

8.3/10Our score

• 1.8mm stainless steel nozzle and needle
• 34 fluid ounce cup
• Brass 7-hole hood
• Aluminum construction

ENDOZER is a lightweight air-powered siphon gun with a 1.8mm nozzle and 34 fluid ounce cup. It fits finishing and detail work with low viscosity paint.

See it on Amazon

Pros

• Lightweight 0.99kg body
• Brass 7-hole hood
• 1.8mm stainless steel nozzle

Cons

• Low viscosity paint focus
• Only one nozzle included

The ENDOZER Professional Siphon Feed Spray Gun is a lightweight choice for finishing and detail work with low viscosity paint. It has a 1.8mm stainless steel nozzle and needle, a 34 fluid ounce cup and an aluminum body.

Its brass hood uses a 7-hole design for atomization. Holes around the cap help spread air around the paint stream, which supports a more even fan for finishing work.

The gun also has an exclusive air valve design and an easy trigger pivot. A lighter trigger pull can reduce fatigue when you make many short passes on furniture or craft pieces.

ENDOZER describes it for cars, walls, furniture repair, art, crafts, ceramic resin and clothing spray maps. The product data lists stainless steel, brass and aluminum as its materials, which suit normal paint use and cleaning.

For set up, keep paint to the low viscosity range it targets and test the pattern before starting. For care, flush the gun after use and check the needle and nozzle for residue that can disturb the fan.

Choose ENDOZER if handling weight and a low viscosity paint focus matter. The single 1.8mm nozzle gives you less setup flexibility than the Throohills set.

9

AP Astro Pneumatic Tool 4008 Spray Gun: Best for primer and heavy coatings

8.1/10Our score

• 1.8mm nozzle
• 1 quart dripless cup
• Adjustable wide fan pattern
• 50–60 PSI operation

The Astro Pneumatic 4008 uses a 1.8mm nozzle and 1 quart cup for primers, heavy coatings and glues. Its stated 50–60 PSI operation and 7–12 CFM average air use need a suitable compressor.

See it on Amazon

Pros

• 1 quart cup
• Wide fan control
• Replacement cup included

Cons

• Requires a 3 HP compressor
• Heavier 2.5 lb body

The AP Astro Pneumatic Tool 4008 Spray Gun is a practical choice for primers, heavy coatings and glues. It uses a 1.8mm nozzle, a 1 quart aluminum dripless cup and an adjustable wide fan pattern.

Astro Pneumatic lists operation pressure at 50–60 PSI and average air consumption at 7–12 CFM. It also lists a required 3 HP compressor, so check your compressor output before choosing this gun.

Those air needs are the main planning point for this model. A compressor that cannot keep up will make wide passes harder to keep even, especially with primers and heavier coatings.

The package includes the spray gun, dripless cup and replacement cup. A replacement cup can save time when you switch coatings or need to clean one cup while the other is in use.

The maximum pattern at 8 inches is 11 inches, which gives you a stated reference for broad passes. Keeping a steady distance and moving at an even speed helps you use that fan width without heavy edges.

Choose Astro Pneumatic when its primer-focused design and 1 quart cup fit your work. It is a heavier 2.5 lb gun and needs more compressor planning than some smaller setups.

What cup size should a siphon feed spray gun have?

A 1000cc or 1000ml cup is a strong starting point for larger paint batches, while a 34 fluid ounce or 1 quart cup also gives useful capacity. Choose the largest cup you can hold comfortably without making the gun tiring during long passes.

Larger cups reduce refill stops, but a full cup adds weight below the gun. Weight also changes as paint is used, so plan work in sections and keep the gun moving at a steady distance.

The Throohills and AutoViteX models use 1000cc or 1000ml cups. Dynastus also uses a 1000ml cup, while Astro Pneumatic uses a 1 quart cup.

ENDOZER uses a 34 fluid ounce cup, which still gives useful capacity for finishing work. The right size depends on the surface you paint and how often you are willing to stop and refill.

For detail work, a smaller cup can be easier to control and wastes less paint at the end. For walls, fences and large furniture, a larger cup usually saves time.

Cup material also matters in daily use. Aluminum cups are listed for several models here, and they should be cleaned after use so paint does not harden inside.

For a fence project, compressor sizing matters as much as cup size. Use our guide to fencing paint spray gun cfm before you choose a gun for long outdoor passes.

If you plan long passes outdoors, check the air supply before you fill the cup. A large cup cannot fix a compressor that drops pressure mid job.

Which nozzle size is best for siphon feed paint?

The best nozzle depends on the coating and finish you need. Smaller openings such as 1.4mm suit more controlled work, while 1.8mm and 2.0mm cover many general tasks and Dynastus uses 2.5mm for oil-based or latex paint.

A smaller opening usually helps control, while a larger one moves more paint for broad surfaces. Paint preparation, air pressure and your passes still decide whether the finish looks even.

The Throohills set is the easiest choice when you are unsure because it includes 1.4, 1.7 and 2.0mm nozzles. You can start with one size, test it, then switch if the coating needs more or less flow.

ENDOZER and Astro Pneumatic use 1.8mm nozzles, while AutoViteX uses 2.0mm. Those middle sizes fit many jobs, but they give only one fixed opening.

Hotorda includes 0.8mm and 1.4mm guns for smaller work, and VONFORN includes 1.0, 1.5, 2.0 and 3.0mm nozzles. The range shows how nozzle choice follows the task, not just the brand.

For automotive basecoats and clearcoats, a smaller Throohills nozzle can suit finer coats, while a larger one can help on bigger panels. For furniture and walls, 1.8mm or 2.0mm is a common starting point.

Always strain paint before it enters the cup, then adjust fluid and air controls gradually on a test surface. Many spray problems come from paint too thick for the nozzle, so check thinning and filtering first.

Keep notes on the nozzle, pressure and paint mix that worked. Clean the nozzle after each session so dried paint does not narrow the opening.

How do you set up a siphon feed spray gun?

Start by choosing the nozzle for the coating, straining the paint and filling the cup without overloading it. Connect the air hose, set the pressure within the gun's stated range and test the pattern on cardboard or scrap material.

Keep the gun moving before you pull the trigger fully, and overlap each pass evenly. Adjust fluid, fan and air controls in small steps so one change does not hide the effect of another.

Wear suitable eye and respiratory protection for the coating and work in a well-ventilated area. Cover nearby surfaces because spray can travel beyond the target.

If your compressor is the limiting factor, compare it with our guide to the best air compressor for spray gun. For automotive projects, read can you use an air compressor to spray paint a car before you plan the job.

How do you clean a siphon feed spray gun?

Clean the gun immediately after spraying by emptying the cup, flushing the paint path with the appropriate cleaning liquid and brushing residue from the nozzle and passages. Delayed cleaning can leave paint inside and cause clogs.

Use the cleaning items included with the model when they fit the job. Throohills sets include cleaning kits, Dynastus includes brushes and cleaning kits, VONFORN includes a cleaning brush and nozzle needle, and Hotorda includes a brush cleaning kit.

Fresh paint is easier to remove than paint that has dried. Do not leave paint sitting in the cup during a break, because it can skin over and make the next pass uneven.

Remove the nozzle and other serviceable parts only as the instructions allow. Extra force can damage small parts and spoil the fan pattern on the next job.

Brush gently around the needle and nozzle tip to clear residue. Strong picks or rough tools can scratch soft metal and change how paint flows.

Flush until the cleaning liquid runs clear from the gun. That check helps you know whether paint is still trapped inside.

Clean the cup and lid as well as the gun body. Paint can hide around the cup rim and feed tube even when the outside looks clean.

Let the gun dry before storage, with parts stored as the instructions allow. Keep strainers, brushes and wrenches with the gun so cleaning is easy next time.

Siphon feed spray gun verdict

The Throohills HVLP Siphon Feed Spray Gun Set is the best siphon feed spray gun for most buyers who want a 1000cc cup and 3 nozzle sizes. Its 1.4, 1.7 and 2.0mm stainless steel nozzles cover more setups than a single fixed nozzle.

Choose Dynastus for oil-based or latex paint, AutoViteX for adjustable controls, and Astro Pneumatic for primers and heavy coatings. Match the gun to the paint first, because each solves a more specific job.

Dynastus uses a 2.5mm nozzle and needs at least 5.0 SCFM at 40 PSI. AutoViteX uses a 2.0mm nozzle with a suggested 50-70 PSI setting, while Astro Pneumatic lists 50-60 PSI and a required 3 HP compressor.

ENDOZER is the lighter 1.8mm option for finishing and detail work with low viscosity paint. The single-nozzle Throohills model also uses 1.8mm and suits a simple setup with a 1000cc cup.

Choose Hotorda when gravity feed and two smaller cup sizes fit better, since its 0.8mm and 1.4mm guns suit smaller batches but it is not a siphon gun. Pick VONFORN for an AC handheld sprayer and Milton for liquid cleaning rather than paint application.

For most paint jobs, start with the Throohills set and test each nozzle on scrap material. Strain the paint, set the pressure, then clean the gun right after use.

Frequently asked questions

What is the best siphon feed spray gun for large paint jobs?

The Throohills HVLP Siphon Feed Spray Gun Set is the strongest match for large paint jobs because it combines a 1000cc aluminum cup with 1.4, 1.7 and 2.0mm nozzles. Dynastus and Astro Pneumatic also suit larger work, but each uses one main nozzle size.

What is the difference between siphon feed and gravity feed spray guns?

A siphon feed gun draws paint from a cup below the gun, while a gravity feed gun lets paint move down from a cup above it. Siphon feed models can suit larger batches, while gravity feed guns often make sense for smaller amounts and detail work.

How much compressor power does a siphon feed spray gun need?

The requirement depends on the gun. Dynastus needs at least 5.0 SCFM at 40 PSI, while Astro Pneumatic lists 7–12 CFM average air use and a required 3 HP compressor.

Match the compressor's delivered air to the gun before spraying.

Is a Husky siphon feed spray gun included here?

No Husky siphon feed spray gun is included in this comparison. The picks are the supplied products, including Throohills, Dynastus, AutoViteX, ENDOZER and Astro Pneumatic, plus alternatives such as Hotorda and VONFORN.
