Spray Foam Guns from SprayWorks

Plural Component Spray Guns with Quick-Change Pattern Control Tips

Graco PMC logos

Ranging from Graco Fusion spray guns, to PMC AP-3 and AP-2, we carry a full line of spray foam guns and polyurea spray guns with dynamic features for application.

The technologies in these spray guns combine rapid trigger response, superior atomization, and quick-change spray pattern size to output combination allowing for longer duration for spraying.

Types of Spray Foam Guns

Air Purge Spray Guns

PMC AP3 Spray Gun

The Graco and PMC AP series spray guns provide the operator with easy to operate and maintain spray guns that can be used in a variety of applications. These air purge guns provide the operator with simple output changes by simply removing and replacing the appropriate size chamber right from the front of the gun with no gun disassembly required.

The design of these guns allows the applicator to leave the gun connected to the hose set at the end of the day by simply pumping a small amount of grease into the mixing area.

Some of these gun’s features include a revolutionary 360-degree rotational head allowing hoses to be connected to the top or the bottom of the gun, a quick-change mixing chamber that allows for removal from front of the gun without having to disassemble two different air connection locations, and one piece machined mixing chambers and new air cap designed to protect mixing chamber tip.

Mechanical Purge Spray Guns

Fusion MP

Graco Mechanical Purge Spray Gun provides the applicator with a spray gun that has been designed to reduce operator fatigue and facilitate application control. With this aim, a new ergonomic gun handle has been developed and placed at the center of balance to equalize weight distribution and provide enhanced stability during the application.

All models include a tool kit with the necessary tools for proper adjustment and maintenance of the gun. Some of this gun’s features include superior mixing, while the mechanical cleaning minimizes reacted material inside the mixing camber. Easy spray pattern tip change out without having to change the mixing chamber and a powerful air cylinder to facilitate rapid valving reaction.

Spray Foam Guns We Carry

The AP-3 Polyurethane Spray Gun – Designed for the Ultimate Spray Application Performance

PMC AP3 Spray Gun

The AP-3 polyurethane spray gun is ergonomically designed for a firm ultra-light fitting (2.4 lbs W/O coupling block). Within its trigger and air cylinders, straight forward air ports and short trigger stroke allow for a very powerful and rapid response ensuring a full spray pattern with every shot.

Polyurethane Machinery Corporation’s two-piece combination mixing chambers and quick-change Pattern Control Tips (PCT) are precision drilled to uniquely and uniformly blend your product mix, creating superior atomization while maintaining your spray pattern in full.

The option to quickly change the PCT provides the spray mechanic a choice to change spray tip and size without disassembly of the spray gun, allowing more time spent spraying and perfecting skills for consistency and aesthetically pleasing profiles resulting in top quality applications.

In product testing for military and marine applications, the products meet and exceeded chemical manufactures expected physicals property requirements. Flow back check valve separates the fluid portion from the dry side of the gun eliminating material cross contamination into the air passages of the air cylinder and trigger handle assembly!

Mixing chamber ball and socket connection makes for fast change out and eliminates the screw type assemblies. Right out of the box, you can have it spraying in no time at all.

The AP-3 is simple to operate, easy to service, and does not require end of day disassembly which makes for end of day shut down take just seconds!

Unique Features
  • Design – Simplified heavy-duty design components have longer a lifespan and are inexpensive to replace, providing the best value over other designs
  • Rapid Trigger Response – Easy to access, straight forward air ports and short trigger stroke allows for a very powerful and accelerated rapid trigger response action, ensuring immediate spray pattern development
  • Crossover Protection Design – Purge air check valve eliminates cross over material in the air cylinder and trigger handle assembly
  • PCT Precision Air Flow Design – Reduces rapped build up in front of the spray tip orifice

  • Universal Manual Valves – Manual Valve assembly adapts to existing types of coupling block assemblies
  • Manufacturer’s 1-Year Warranty – PMC proudly stands behind their product lines and provides the industry’s best service and support
  • Newly Designed Mixing Chambers – Ball and socket connection makes for fast change out and elements set screw assemblies
  • Quick-change PCT (Pattern Control Tip) – Allows the contractor to change spray pattern size without disassembly of the spray gun, giving the spray applicator more precise application combinations
  • Mixing Chamber and PCT Combination – Advanced design for pattern development and mixing provides superior atomization
  • Fluid Block – Easy access fluid block makes the mixing chamber change out a breeze
  • Easy Access A & B Filters – Easy-to-clean filters with multiple size screen mesh options allow for more consistent material flow for different types of material viscosities
  • Universal Coupling Block – Quickly adapts to existing types of coupling block assemblies and easily adapts to other types of spray foam and polyurea equipment
  • Made in the USA!

Graco Fusion Spray Gun

Graco Fusion AP

The Graco Fusion Spray Gun features and easy air-blast tip cleaning which helps reduce build-up and tip clogging. The spray gun’s long-lasting side seals means less downtime for maintenance, and applicators enjoy a quick-release fluid housing – which allows for you to easily change the mixing chambers without the use of tools.

If you need to remove the front cap, it can be easily removed or replaced by the hand-tightened front cap – no tools are needed for cleaning of the spray gun, and it maintains the seal and mix chamber.
