Accuspray: Spray Gun Systems Built Around Replaceable Atomizing Heads

Accuspray is a line of HVLP spray equipment sold under the 3M umbrella and designed for automotive refinishing and industrial coating work. Rather than asking painters to rebuild and maintain a traditional gun, Accuspray takes a different approach: a lightweight, one-piece composite gun body paired with replaceable atomizing heads, so each new head restores the performance of a fresh gun.

What Makes the Accuspray Approach Different

A conventional spray gun needs regular teardown, cleaning and maintenance kits. The Accuspray ONE gun body is described by the manufacturer as simple to maintain, and its see-through atomizing heads can be reused several times before being swapped out. That design shortens downtime between jobs and helps keep spray patterns consistent from the first panel to the last.

The guns are built to work with the PPS Paint Preparation System, a closed system of reusable cups with disposable lids and liners. Paint is measured, mixed, filtered and sprayed from the same container, which cuts cleanup solvent use and prep time. Because the liner is sealed, the gun can also be used at nearly any angle, including upside down, which is handy for rocker panels, wheel wells and other awkward areas.

Atomizing Heads and Refill Packs

Atomizing heads are color-coded by size to match coating viscosity. Smaller heads suit thin waterborne and solvent basecoats, mid-range sizes handle primers and clear coats, and larger 1.8 mm and 2.0 mm heads are used with the HGP gravity-pressurized gun for thick materials such as high-build primers, adhesives, undercoatings and gel coats. Refill packs and multi-pack replacement kits make it easy to keep a full range of head sizes on hand for different stages of a repair.

Systems, Valves and Accessories

• Complete spray gun systems: kits such as the Accuspray ONE with standard PPS or PPS Series 2.0 bundle the gun, cup, lids, liners and multiple head sizes.
• HGP system: a pressure-fed configuration aimed at high-volume, high-viscosity coatings in collision repair.
• Air flow control valves and regulators: let painters fine-tune inlet pressure for HVLP performance.
• Refill packs: color-coded heads in 1.2 mm, 1.4 mm, 2.0 mm and other sizes for PPS-compatible guns.

Choosing the Right Accuspray Components

Start with the coating you plan to spray, since viscosity determines head size. Check whether your setup uses the original PPS or PPS Series 2.0 cups, and confirm compatibility before ordering refill packs. If you regularly shoot heavy-bodied materials, the HGP system and its larger heads are worth a look; for general primer-to-clear work, the ONE gun system covers the widest range from a single tool.

Note that some Accuspray equipment is marketed for industrial and occupational use, so review the product details to make sure a given item fits your application.
