Page 6: Section 3: How It Works
Preface: The H220 uses an integral power amplifier piston together with two diaphragms to yield a pressure ratio of 3:1 [e .g ., 6 .9 bar (100 psig) air inlet will develop liquid discharge pressures up to 20 .7 bar (300 psig)] . In the H220, air is simultaneously directed behind the amplifier piston a well as one of the diaphragms via specialized air manifold porting. -
