Frequently Asked Questions - vFan Airbrush

The fan tip attachment is designed like a paint gun for painting cars. The tip is designed to give the user a better, more even result over large areas. It can be turned in any angle to give you the most control (up to 3 inches).

The standard tips are used for more precise control and to achieve very fine lines up to an inch.

It depends on how thin the paint is: Thinner paints use 30 PSI and thicker paints use up to 80 PSI.

Dry, calm areas are best. The more wind there is, the more overspray there will be and the harder it will be to control the paints path.

Yes, as long as it is a well-ventilated area. Using a mask is always recommended.

The best method is what we call the 30-3 rule. Use the vFan Airbrush for 30 seconds continuously and stop for 3 minutes so the 150 Feet of Energy does not get too cold. While waiting 3 minutes, shaking the can helps warm the propellant faster and keeps your PSI at a proper range of 15-65 PSI.

Almost anything (oils, liquids or paints) thinned to the manufacturers’ recommended thinning guidelines. With regards to viscosity, keep the liquid a bit thicker than milk.

Yes, when using the vFan Airbrush with a air compressor that has proper filtration. Most food additives are fda approved, so it is safe for spraying food as long as the product you are spraying is also safe. We don’t recommend using 150 Feet of Energy when spraying foods.

With the vFan Airbrush, you can expect up to a 2-3 inch fan spray pattern. With the standard tips you can expect hair thin lines and up to 1-inch round thick lines.

The 150 Feet of Energy power source is practically silent. The only sound that can be heard is the air coming out of the tip of the airbrush, which is a soft hiss.



Paint is not coming out of the vFan Airbrush consistently or not at all.

1) Tip may be clogged. Take the head assembly apart and spray it with 150 Feet of Energy to clean it. If that doesn’t work, clean with Q-tips®.

2) Dip tube is clogged. Take strainer off of dip tube and clean; spray 150 Feet of Energy through the dip tube.

3) Clean the vent at the top of the bottle with 150 Feet of Energy.

4) Email for more information.

Bubbles are going through the straw into the bottle.

1) Make sure head assembly is tightened with wrench.

2) Make sure O rings are in place.

3) Use wax or chopstick on tip threads to seal butter.

4) Make sure needle assembly matches with head. 

Example: Size 2 head needs to be with size 2 needle.

There is no pressure coming out of the vFan Airbrush. 

1) Check to make sure the regulator valve is sealed correctly and turned all the way down on 150 Feet of Energy.

2) Check to make sure the trigger is seated correctly.

3) Make sure hose has no kinks in it.

4) Disassemble the airbrush and reassemble, making sure all parts are in the proper place.


When I spray paint, the paint is coming out splattered or crooked.

1) Check the tip of the needle with a cotton ball to make sure the tip is not bent. The tip is fragile and can bend easily.

2) Check tip with cotton ball to make sure the tip is not cracked.

3) Clean entire airbrush thoroughly with 150 Feet of Energy. If there is paint that can’t be removed, you must soak the parts separately in solvents.


No. Each company uses very specific lengths and diameters on their tips and needles. They are not compatible with other airbrushes.

The power from the can is a liquid propellant from Dupont called 152a. When the propellant is being used the liquid state is turning into a gas. As this process occurs, the propellant begins to drop in temperature and begins to cool down the can.

The airbrush must be attached to an air source or power supply. In this system, we offer two cans of 150 Feet of Energy for portability and ease. We also recommend air compressors for larger projects. To use the vFan Airbrush, push down on the trigger to start the airflow. With the trigger pushed down, begin pulling back to spray the paint. The farther back you pull the trigger, the more paint will come out.

Any surface that can hold paint can be airbrushed. You must ensure what you are spraying is compatible with the surface you are spraying onto.

An airbrush is used when you want a softer more even look with no visible paintbrush strokes or roller marks.

Soaking the parts of the vFan airbrush that have paint on them in thinner is ok. But soaking the whole airbrush, you should only do this for a few minutes as the thinner will remove the lubrication that helps all the parts move smoothly. You are better off cleaning the airbrush with cleaning solution or with the paint thinner, using qtips and a cloth, before storing.

Get close to what you’re going to spray onto and use less paint. You can move faster as you spray.

Use the fan spray, use more paint (pull back at least halfway). Overlap your passes by 40% to 50%.

It’s a good idea to lubricant your airbrush regularly. Lubrication keeps the airbrush parts working smoothly. Only use airbrush lubrication, we will be coming out with some shortly so email us at DON’T USE WD-40!

Usually when paint isn’t sticking to a surface, it is because the paint has nothing to “grab” onto. Scuffing up the glossy finish with 1,000-grit sandpaper or lightly with an SOS pad will help. Adhesion promoter will also help. After scuffing, wipe the surface with a degreaser.

The patent application is focused around the functionality of the system. Because its only a patent pending we have to be careful discussing too much detail.

You wont find another system like this in the market. key features:

  • Comes with fan aircap and detail aircap
  • No compressor is needed but works very well with them.
  • The aircaps are interchangeable by simply screwing off and on.
  • The portable power units are also registered dusters making for cleaning up sanding debris a breeze.
  • Made in the USA with easily replaceable parts when needed
  • Sprays latex, clear coat, urethane, water based,and solvent based paints and industrial coatings like no other
  • Perfect professional touch up spray system with 1/16th" to 3" fan.
  • Easy enough for a DIYer
  • Made of stainless steel and brass, innerpacking using solvent proof cpating
  • Packaging comes with built in display for retailers to use if they like, bilingual.
  • Priced below anything similar, see Iwata kustom airbrush as an example, of similar quality at a much, much higher price.

•    DO NOT work in direct sunlight

•    Remove rails, cleats, louvers, snaps, striping tape, etc. Remove seals from the edges of parts or fittings when doing a repair around that part or fitting.  Clean repair area and all tools with acetone prior to application. Spray acetone to clean out Sprayer and/or vFan Airbrush.

•    Duct tape off adjacent gunwale molding, and deck fittings you are unable to remove. Duct tape is recommended over masking tape because it provides better protection.

•    Gel coat should be applied in temperatures of 60ºF to 80ºF

•    Always use eye and hand protection. Read all warnings on product labels

•    SAND DAMAGED AREA  -The heavier fast-cut grits (40/80/100) are used to feather sand and ground out a routed area prior to filling. Also, they are used for the first sanding of gouges, dock dings, scratches, and blisters. When sanding areas that have been filled with putty we suggest using 40 or 80 grit sandpaper, depending on how large the repair is.

•    Once the fill area is level or contoured to the desired shape, sand with 100 grit paper to remove the course scratches from 40 or 80 grit. You should also feather the surrounding area of the gelcoat repair with 220/330.

•    When sanding flat areas use a rubber block. We recommend 3M Abrasives for best results.

•    CATALYZE  FRESH BATCH OF GELCOAT properly. Measure catalyst accurately. Under- or over-catalyzed gel coat will cure slower and look faded or chalky.

•    Do not add more than 15-20% by volume of Styrene Monomer

•    Pot life (amount of time for application of the product) shortens dramatically as you mix larger batch sizes. Keep in mind that you have a limited time to apply what you have mixed (usually between 5-15 minutes).

•    Gel coat will not fully cure without adding a surfacing agent or over spraying with PVA

•    Spraying Gelcoat Check color thoroughly before applying. Gelcoat will not darken or change colors when it dries. The color wet is the color when dry.

•    Generally mix 5oz batches. A good practice is to pour the mixed gel coat from the mixing container into Peval Product container used for application. This further assures that no uncatalyzed material is clinging to the sides of the pot. “Lay on” the gel coat in a heavy thickness (about 10 mils) using horizontal strokes, and working from top to bottom. Avoid brushing as this could remove the waxy surface additive. Remember to always lap wet.

•    Generally, one heavy coat is sufficient. However, if you have opacity problems two coats may be necessary with a light sanding between coats. Once the coating (gelcoat) has cured, it should be block sanded using a 250 wet grit paper to remove all brush marks and high spots. Following this, it should be wet sanded with 320,400 and 600 wet grit paper, buffed, polished and waxed.

•    If there is a trim color, you need to switch the fan aircap from the  vFan Portable Airbrush System and replace it with a standard aircap. Gel Coat requires the addition of fiberglass resin hardener or catalyst (MEKP) at 2% by volume (77ºF) Measure catalyst accurately. Measure catalyst properly as using too much or too little may effect curing and cause fading and chalking. Gelcoat will not fully cure without adding a surfacing agent or wax additive sanding aid. You can spray with PVA before gel coal reaches its gel stage (5-10 min.), or adding 1oz per quart of wax additive sanding aid.

•    Gelcoat may be thinned for use in a Portable Preval Sprayer with styrene monomer. The Sprayer is an amazing spray system however Acetone is NOT recommended except in clean up. Do not use more than 15% by volume of thinner, and always add thinner, tint, OPR metal flake first then add the Catalyst or Hardener and mix thoroughly. Over thinning will result in an inadequate thickness for full curing.  

•    For more detail and precision we recommend using vFan Portable Airbrush System which works with your compressor and is designed for portability, precision paint atomization and material dispensing; for professional touch-ups and surface repairs; surface preparation; and fast curing. The vFan Airbrush delivers a 3” fan and a 1/16” hairline spray pattern.  The dual action vFan is easy to control allowing the user to manage air volume and product output. This precision-based technology allows vFan Airbrush users to atomize product finish coatings, paints and chemicals with nano-sized droplets for ultra-thin layering to feather, blend and to speed up cure times. Initially spray a cover coat as smooth and evenly as you can to cover your repair. This coat should be mostly in the repair area, and may be repeated. Sanding between coats is not necessary unless a surfacing agent has been added to your gel coat. Once your repair is covered, feather a ‘flow’ or sanding coat on the masked-off area making layered passes to avoid a buildup of gel coat in any one area.

•    Each of these coats of gelcoat may involve several passes. Be even and consistent in your Sprayer or vFan movement, overlapping each previous pass slightly and not hesitating on the ends. When spraying to a radius, flow the gelcoat to the tape. In open flat areas, layer passes. Final thickness should be 12-15 mils minimum or the gelcoat may not fully cure. As soon as you are done spraying, clean your sprayer fully with acetone. Most re-sprayed gel coat will cure in 2-4 hours, although overnight cures are ideal. Begin wet sanding with the finest grit that will remove orange peel in the re-sprayed area. This will avoid unnecessary sanding scratches. Usually 320 or 400 grit wet paper is sufficient for the initial sanding. Wet sand to a 600 finish and buff with 3M Finesse-It Marine Compound and polish with Scotchgard Marine Liquid Wax.

•    Store gel coat in a cool, dry place.

The dual action vFan Airbrush allows for the user to control air flow and product output.  This precision based vFan Airbrush is capable of atomizing coatings, paints, chemicals at nano size droplets giving ultra thin coatings or dispensing thicker coatings at a 1/16th" pin pattern to a 3" fan pattern.  Further the vFan works with compressors as well as being portable using pressurized gas which is necessary for certain Industrial, automotive and other industries

The vFan will absolutely be the best option.  For larger projects like this we recommend using the vFan with a standard plug in compressor.  Otherwise our 150 feet of ENERGY will work fine but because the portable units are more designed for "on-the-fly touch-ups" you should buy an additional 2-3 units to interchange throughout the job.

Yes . The Preval vFan air hose  is built with 1/4" NPT female compressor fitting for our vFan regulator for both our 150 feet of ENERGY  and our Ultralight compressors. Typically fitting sizes are 1/4" - 1/2" we just happen to work with the 1/4" size.

If your compressor has a fitting that is larger they can go to Home Depot or any other similar retailer and purchase an adapter to pair a different size.  Typical cost is a few dollars.

You will need a minimum of 20 PSI @ .5 CFM or 1/6th hp for a compressor.

1. Attach the one end of the air hose to the pressure regulator valve which is secured onto the 150 feet of energy.

2. Feed the other end of the air hose through the bottom of the EDU lid and Screw into the bottom of the airbrush.

3. Control air flow pressure by turning the pressure regulator valve clockwise.  Test spray vFan.  Adjust pressure regulator to meet the needs of atomizing the paint

4. Once adjusted, add room temperature water into the edu, 75% full of 750 ml, and submerge the 150 feet of energy into the EDU and secure the lid.

5. Edu will keep the 150 feet of energy from freezing up, for long lasting continuous spray.  After 5 minutes or so, or if you notice any inconsistencies with spray performance check the 150 feet of Energy can as it may be getting close to bring empty, evacuated.

The Sprayer and vFan Portable Airbrush System fills a void in all of the Coatings Industries from Industrial, Contractor; and Consumer Users. By simply connecting an aerosol can to our Delivery system any Coating User can professionally deliver unadulterated, fine finishes, touch-ups and coatings for small surfaces.

What industry experts are telling us is Iwata's Kustom TH is a competing touch up Airbrush which also features a fan spray pattern.  The main differences include:

  • vFan comes with a .9mm (tip, needle and cap) and is adjustable to .66mm and .38 mm heads Whearas the Iwata Kustom is stnadard with a .5mm  - therefore vFan sprays thicker viscosity products, metallics, and more product flow.
  • vFan can go portable with our cans of 150 Feet of ENERGY and can work off of any electric compressor airsource using  only .5 CFM where the Iwata requires 1.2CFM and must be used with an electric compressor only therefore the vFan is much more versatile
  • vFan Portable Airbrush System has a MSRP of $199.95 and the system includes an airhose, an additional needle , 3 product containers, tools, extra dip tubes, a regulator, and 2 cans of 150 Feet of ENERGY compressors and more, whereas the Iwata Kustom TH retails for around $400 and only comes with the airbrush therefore the vFan Portable Airbrush System is far less expensive.
  • vFan is a siphon fed system allowing for greater control of spraying most paints and coatings design for touch ups whereas the Iwata Kustom TH is a gravity fed unit with limited product control and mostly engineered for the crafting.
  • vFan is made in the USA - Iwata is made in Japan

Here is the link to the EDU How To Guide

The vFan system is adjustable no matter which size you use as its dual action system; so you can adjust the size of the spray pattern by following 2 steps:
1) pulling the trigger back increases paint volume
2) the closer or further you bring the vFan to the surface your spraying will naturally adjust pattern size

Yes.  Particularly works well with our standard .9mm fan cap - Our vFan is ideal for spraying PVA.

 The key is testing it first by thinning it with water and based on those results you'll know of less or more water is needed.

Afterwards, make sure you clean the vFan with warm soapy water.

If you have large surfaces that need PVA spraying you should also buy our EDU-.
