AP-3 Air Purge Gun
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.
