42AAV48 Gas Boosters and System

5 to 1 Boost Ratio, 0-8 scfm Flowrate

This gas booster uses shop air to boost the pressure of an inert gas stream. The maximum discharge pressure is the sum of the gas inlet pressure plus 4 times the shop air pressure. The table below shows the maximum flowrate capability with 80 psi shop air and a typical range of inlet and discharge gas pressures.

Construction

The major components of the gas booster are anodized aluminum. The hardware components, check valves and piston rod are stainless steel. The air cylinder and gas cylinder are seperated by a distance piece which prevents cross contamination between the shop air and the gas. The boost cylinder has a cooling jacket which uses exhaust air from the drive cylinder as the cooling medium. 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 explosion proof.

Operation

Shop air is fed into the 4 inch diameter drive cylinder and the gas stream is fed into the 2 inch diameter boost cylinder inlet port. Both the gas flowrate and the gas discharge pressure can be controlled by throttling the shop air flowrate and/or regulating the shop air pressure. The air piston reciprocates automatically and drives the gas compressor piston. When there is no demand for high pressure gas, the boosters stall when the maximum discharge pressure is reached. When there is a need for high pressure gas, the pressure in the discharge line drops which causes the boosters to restart automatically. No shop air is consumed when the boosters is stalled.
