Adding 3M™ PPS™ to Your HVLP Spray Gun

Fuji Spray HVLP spray guns are great, just the way they come. However, there are accessories to make them even better.

These include different air cap sets, remote controls, and my new favorite add-on… the 3M™ PPS™ disposable spray cup system.

The latest version, the 3M™ PPS™ 2.0 system, offers several variations to choose from. They are mainly divided into basic “lid and liner” or pressurized cups. Both options are compatible with their disposable cup liners and are available in various sizes.

Start with the basics

The standard lid and liner kits include a plastic cup to replace the metal or nylon cup in your Fuji Spray HVLP spray gun.

Each time you spray, you insert a thin, disposable liner into the cup. Luckily, the lids feature an integrated filter to strain every last drop of fluid before it enters the chamber of your gun. The filters are typically 200 micron (white lids) or 125 microns (blue lids). The black rings on these lids are threaded, and allow a simple twist-lock installation.

Plug and Store to Reduce Wasted Paint

A typical kit comes with a reusable plastic cup along with 50 disposable lids, 50 liners, and 32 plugs. The standard cup size is 22 ounces, while larger cups come in at 28 ounces. These plugs allow you to seal off any remaining paint or finish for future use.

I’ve always found Fuji Spray guns easy to clean, but this system makes it even quicker.

Invert to Store

Just remember to flip the cup upside down between spray sessions. This ensures that the integrated filter remains submerged in paint, preventing it from drying out.

Your thinned mixture of paint, lacquer, or waterborne topcoat can be stored like this for days.

Pressure Assist Port: Use it or Cap It Off

If you’re using the basic lid and liner system, you’ll need to cap off the pressure assist port on your spray gun.

This is a T70 bottom feed spray gun with the metal 1QT cup removed. When you remove the cup and pressure tube/check valve assembly, it leaves an unused port at the back of the spray gun. Cap off this port with a small vacuum seal cap to prevent any air leaks.

Pressure Cup Option

Another option available with the 3M™ PPS™ 2.0 system is the pressure cup.

This is a thicker plastic cup (shown in the 28oz size), that uses the same disposable lids and liners as the first option.  To use the pressure cup, simply insert a liner into the cup (accepts both 22oz and 28oz liners) and prepare the lid.  Remove the black ring on the lid and discard it. The black threaded ring is not needed for the pressure cup system.

Feel the Pressure Building

The pressure cup functions similarly to the original Fuji Spray cup, utilizing a pressure assist tube.

Included in the 3M™ PPS™ Pressure Cup kit is a flexible, rubbery pressure assist hose, which connects to a fitting located at the base of the hard plastic cup.

Trim as Needed

Since the 3M™ PPS™ pressure cup is designed to fit a variety of spray guns, you may need to trim the pressure assist hose to fit your model. Wire cutters work fine for this task.

Install the Pressure Assist Hose

Attach the flexible pressure assist hose to the port at the rear of the gun, just like the factory Fuji Spray setup.

Rotate the hose

If you rotate the hose around the front of the gun, it will have plenty of slack as you unscrew the cup. Plus, it keeps the pressure assist hose away from your hand as you spray!

A Little Help from an Adapter Kit

Both systems require an adapter to connect the Fuji Spray gun to the 3M™ PPS™ cup.

Use the long adapter #26054 (shown above) for the popular T70 bottom feed spray gun. For the T75G gravity feed spray gun, a shorter #26003 adapter is used.

These adapters let you easily install or remove the cups with a simple twist.

As pressure is supplied from the gun through the flexible hose, you’ll notice the paint liner collapsing. This is what makes the system so effective at maintaining constant positive pressure, mirroring the factory Fuji Spray setup.

The result is an uninterrupted spray pattern, for professional results spraying cabinets, trim, or fine furniture.

Spray Upside Down!

Using the pressure cup, you can now spray in a completely inverted position. This is extremely helpful when spraying inside cabinets and other confined spaces.

Only a Pressure Pot can Compete

Once you experience the ease and versatility of spraying in any position, including completely inverted, you realize what a benefit it is.

Here, a 2QT Fuji Spray pressure pot supplies urethane-modified paint to a T70 spray gun. Now you can add the 3M™ PPS™ pressure cup as another way to get this same advantage.

A Great Place to Start

If you’re just getting into the world of fine finishing, start with a turbine-style sprayer like this variable-speed Q5 PLATINUM system, and popular T70 pressure-assisted HVLP spray gun. From there you’ll be well-positioned to add great accessories like the 3M™ PPS™ 2.0 system.
