5 to 1 Boost Ratio

This gas booster compressor uses shop air to boost the pressure of a separate air stream. Shop air is fed to the 4 inch diameter drive cylinder and the 2 inch diameter boost cylinder. The air piston reciprocates automatically and drives the boost piston.

Between the air cylinder and the boost cylinder there is a distance piece with a vent port which prevents cross contamination between the shop air and the boost air. The boost cylinder has a cooling jacket which uses exhaust air from the drive cylinder as the cooling medium.

The booster is unlubricated, and uses filled Teflon piston seals and rod seals. It requires no electricity, cooling water, or air-line lubricator and is explosionproof.

The maximum discharge pressure is equal to 5 times the shop air pressure. The table above shows the maximum flowrate capability at various discharge pressures versus several shop air supply pressures.

The discharge flowrate and 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 is a need for high pressure gas, the pressure in the discharge line drops which causes the booster to restart automatically.
