Model Number 44AAV24 Gas Pressure Booster The Model 44AAV24 gas pressure booster system uses shop air to boost the pressure of an air or gas stream. The drive air piston reciprocates automatically and drives the gas compressor piston. The booster is non-lubricated and uses filled Teflon® piston seals and rod seals. It requires no electricity, cooling water, or air-line lubricator and is explosionproof. For air pressure boosting the maximum discharge pressure is equal to 2 times the shop air pressure. For gas pressure boosting, the maximum discharge pressure is equal to the gas supply pressure plus the drive air pressure. The graphs which follow show the maximum flowrate capability for a range of air and gas supply pressures and discharge pressures. The boosted gas flowrate and discharge pressure can be controlled by throttling the drive air flowrate and/or regulating the drive air pressure. When there is no demand for high pressure gas, the booster stalls when it reaches the maximum discharge pressure. When there W need 1-1/2" Square M I Dis aE S T for high pressure gas the pressure in the discharge line PRESSURE drops which causes the booster to restart automatically.
