THE COMPONENTS

The Fuji Xpc™ Spraygun

The Fuji Xpc™ spraygun features an exclusive side Pattern Control Knob to adjust the size of the Fan Pattern. The spraygun is also non-bleed. This means that air passes through the spraygun only when the trigger is pulled (because Fuji has incorporated a trigger air-valve). All newer Fuji turbines are designed and built with a bleed-off inside the turbine to allow use of any non-bleed spraygun.

The benefits of non-bleed include...

Less blowing around of shop dust and negligible turbulence in the spray area.
Less paint buildup on the tip of the fluid nozzle (especially with water-based coatings).
Spraygun noise (hiss of air) appears to be lessened, because now the hiss of air is intermittent.

The spraygun features a stay-cool nylon handle (fitted over a metal tube), stainless steel fluid passages and an external needle packing adjustment. The fan pattern is adjustable from 1/8” to 12”. You can obtain a professional finish with all known coatings. Fuji does not use O-Rings in any of its sprayguns.

The High-Efficiency™ Aircap

The standard Aircap set is the size number 4H which is .055" (1.4mm) for fine finishing with lacquers, enamels, polyurethanes, latex, water based coatings and more. The 'H' designates the aircap as High Efficiency. Fuji R & D utilized computer Fluid Dynamics programs that yielded data suggesting improvements could be made to the angles and hole sizes in the aircap. In testing, the aircaps exceeded all expectations. The High-Efficency Aircaps provide the user with a cleaner spray pattern that results in less overspray and mist in the air.

This recent addition from Fuji is a greatly improved aircap design. All 'H' stamped aircaps provide the user with a cleaner spray pattern which results in less overspray and mist in the air.

What Fuji has done is reduce the width of the actual fan pattern. If we take a vertical pattern, the height (let's say 9") stays exactly the same, but the width of the HE, compared to standard Aircaps is much less.

What is the advantage of a 'thinner-width' fan pattern? Well, as you know, when you spray across a board, as you come off the edge, particles are spraying into the air and adding to the overspray (mist) in the air. But you have to continue holding down the trigger until you finally pass over the edge of the board. You cannot stop at the edge of the board but must follow through past the board. The wider the width of the fan pattern, the longer it takes to pass off the edge of the board. It is this extra width of fan pattern that is adding to the number of airborne particles with each pass. It becomes even more significant when we realize how many times you pass over the edge of a board when spraying a cabinet or piece of furniture. The Fuji High-Efficiency™ Aircap is an exclusive feature from Fuji.

Four additional color-coded Aircap Sets are available. Please see the Guide to Aircap Selection.

With the Fuji spraygun, it's easy to make spray pattern changes. For a larger or smaller fan simply turn the Pattern Control Knob located on the left side of the front barrel. To change from a vertical to horizontal fan, loosen the front collar and turn the aircap to the desired position - then tighten the collar. By controlling the amount of paint and air, you can even use the Fuji gun like an airbrush for subtle shading or touch-up.

Try setting the smallest pattern and move as close as possible to the surface to be painted and you'll find you can paint with a pattern as small as 1/4". By turning the Pattern Control Knob and moving closer, any size fan pattern between 1/4" and 12" can be achieved. Moving the gun closer reduces overspray and bounceback, plus, it gives you much more control - so move in close when you can.

FUJI TURBINES

All Fuji turbines are industrial-rated. Fuji does not manufacture single or 2-stage systems because they are considered underpowered for many of today's types of water-based/borne coatings. The turbine motor is enclosed inside a durable, heavy-duty steel case. There is an easy-to-reach rocker switch and a separate push-button breaker at the rear. The case exterior is protected (inside and out) with a baked, commercial powder-coated finish. Fuji also manufactures HVLP turbines with different voltages and power cord/plugs for export. Rubber feet protect the floor and help insulate against vibration.

The Mini-Mite™3 Turbine

The Mini-Mite™3 Turbine System uses a powerful 3-stage turbine motor. This is the most powerful turbine motor in its class. Please note* the Model Number is shown on the base of the turbine.

The case is powder-coated heavy-duty steel to last a lifetime. Two washable filters, one coarse, one fine are installed. For years, experts have recommended that 3-stage is the minimum size turbine for spraying the newer water-based/borne coatings. These coatings are formulated using a higher solids content that demands more power. Fuji discontinued their 2-stage turbines years ago to avoid this problem. The MM3 is a professional, industrial-rated turbine. Don't let its size fool you - although amazingly portable, it is a very powerful system capable of spraying any type of coating.

The Mini-Mite™4 Turbine

The Mini-Mite™4 Turbine System uses a powerful 4-stage turbine motor type #119292. This is the same 4-stage turbine installed in most 4-stage systems on the market. We recommend the 4-stage for heavier paints - although you still have to thin. For more information on thinning, please check the FAQ Technical Page.

The Fuji Q-GOLD™ Series QUIET Turbines

The most desirable feature for any turbine is to have it as quiet as possible. Except for the noise level, the HVLP turbines from all makers are essentially the same (but the sprayguns are very different). A standard turbine sounds like a very loud vacuum cleaner. The noise level of a standard turbine is so loud, that over time, it contributes to hearing loss. Many woodworkers use ear protection so the standard noisy turbine is not a problem, but if you have a smaller shop and do not use ear protection (or have employees working in the same shop) we recommend choosing a model from the Q-Series.

Fuji has reduced turbine noise levels by over 50% without causing any unwanted side effects such as overheating or air restriction. No... Fuji does not simply surround the turbine motor with soundproofing foam - this would cause overheating. The method used by Fuji allows the turbine motor to sit in an all-metal enclosure in exactly the same way as in all standard turbines. The Fuji Q-PRO Series™ Quiet turbines have computer-designed airflow configurations that completely eliminate the ‘Direct Sound Paths’ found on ALL low to mid-priced HVLP turbine systems available today. Direct sound paths are responsible for the noise factor. Noise is reduced to less than 50% of previous levels. In fact, when the Fuji Q-Turbine is placed across the room, the low hiss of air passing through the spray gun is more noticeable than the turbine. Fuji Quiet turbines are protected by US Patent No.6644913

If excessive noise is a problem for you, please consider spending a little more for a Q-PRO Series™ Turbine. There is no quieter turbine on the market today.

The Super3 GOLD ™ QUIET Turbine

Fuji has recently introduced two new Quiet turbines to their lineup. The Super3 GOLD™ has the same 3-stage turbine motor installed as the MM3 and Q3 GOLD models. Although not as quiet as the Q-Series, the difference between a standard, noisy turbine and the Super Model is impressive. This is done by using an adaptation of the Fuji patented sound-proofing method. The Super3 GOLD™ models are more economical in price offering the exact same features as the Q-Series.

The Super4 GOLD ™ QUIET Turbine

The second of two new Quiet turbines to the Fuji lineup. The Super4 GOLD™ has the same 4-stage turbine motor installed as the MM4 and Q4 GOLD models. Although not as quiet as the Q-Series, you will appreciate the noise relief on these models. This is done by using an adaptation of the patented sound-proofing method. The Super4™ GOLD models are more economical in price offering the exact same features as the Q-Series.

The Q3 PRO™ QUIET Turbine

The Q3 PRO™ turbine is identical to the Mini-Mite 3 turbine but with the added benefit of noise reduction. The Patented Quiet turbine has only one large washable filter (easily removed and replaced in seconds).

The Q4 PRO™ QUIET Turbine

The Q4 PRO™ turbine is identical to the Q3 PRO™ but with a more powerful 4-stage turbine motor type installed. Recommended for Painters and Decorators spraying latex house paint most of the time. Extra pressure allows for less thinning.

The Fuji HI-FLEX™ Hose

The Fuji Hi-Flex™hose is standard with all 3 systems shown. The solid plastic hoses typical with most HVLP turbine systems are hard and stiff making the spraygun difficult to maneuver. The Hi-Flex™ Hose is not only flexible at different temperatures, it will stay flexible over the years (unlike the plastic hoses that become stiffer with age due to the emission of plasticizers).

The Air Control Valve

Fuji installs the Air Control Valve right where it should be - at your fingertips. Use it to instantly reduce overspray and bounceback.

When would you use the Air Control Valve? Well, for instance, when you have thinned the product properly (so that it levels on its own) you can then turn down the amount of air a little at a time until it starts to affect the finish. Once it affects the finish, you have gone too far. Simply tweak it back to where the coating levels out and looks good. This is the point where there is the least overspray possible with any type of spraygun. Don't worry if the atomized particles are larger - is doesn't matter so long as the finish levels nicely. Usually you would set the Air Control Valve and then leave it set for whole project. But if you are spraying a cabinet or shelf with the back already installed, you may need to adjust to a smaller pattern size and turn the air down even more to reduce 'bounceback'. This can be done mid way through the spray job.

With the air control conveniently located at the gun, there is no need to walk 20ft over to the turbine to turn down the air. With less pressure, there is less velocity, so the spray will not be bouncing back into your face as it would be if you were trying to do the same job with a high pressure gun. Please learn to use the Air Control Valve - it is a great tool for reducing excessive overspray.
