This economically priced gun weighing a mere 2.4 lbs (1.1 kg) is one of the lightest and smallest plural component spray guns on the market today. The Chamber, PCT, Screen Screw Parts, Coupling Block and Check Valves are the same parts used in the proven PMC AP-2 Air Purge Gun.
The AP-3 has fewer parts than the leading competitor. The traditional spool valve method of providing air to move the cylinder has been replaced with a one piece replaceable Cartridge Valve, eliminating the need for multiple O-rings. The short trigger stroke reduces operator fatigue, especially in high triggering applications such as residential insulation. The short trigger stroke also allows precise detail shots that cause competitive guns to struggle. Check valves not only protect against cross-over to the hoses, but PMC has also incorporated a separate check valve to protect the air passages of the gun.
The Advanced Pattern Development and Mixing is accomplished with the unique Chamber/PCT design which provides a multitude of spray pattern and mixing combinations. Chambers are available in all common and half sizes. The hardened PCT’s are available in Round, Flat, Blaster and Pour Configurations. Simple assembly and disassembly is accomplished by having fewer parts and requiring fewer tools to work on this gun. PMC offers the AP-3 with an optional Steel Gun Block.
