Pneumatic Airless Paint Sprayers

The Pneumatic Airless Sprayers use dual acting pump and piston airless sprayers although it’s driven by an air motor.

Those air driven motors are reciprocating motors that usually works with basic compressed air pressure resistance in motor than the pressure of fluid pump.

The pneumatic airless sprayers have different pressure ratio from 10:1, 15:1, 20:1, 30:1, 45:1, 63:1, 68:1, to 73:1.

Different ratio pumps generate different spraying pressure, and different spraying capacity.
