42AAV48 Air Boosters and System

5 to 1 Boost Ratio, 0-8 scfm Flowrate

This shop air pressure booster uses shop air to boost the pressure of a separate air stream. The maximum discharge pressure is 5 times the shop air pressure. The table below shows the maximum flowrate capability at various discharge pressures versus several shop air supply pressures.

Construction

The major components of the air booster are anodized aluminum. The hardware components, check valves and piston rod are stainless steel. The drive cylinder and boost cylinder are seperated by 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 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 2 inch diameter boost cylinder. The drive piston reciprocates automatically, driving the boost piston. The discharge flowrate and pressure can be controlled by throttling the shop air flowrate and/or regulating the shop air pressure. When there is no demand for high pressure air, the booster stalls when it reaches the maximum discharge pressure. When there is a need for high pressure air, the pressure in the discharge line drops which causes the booster to restart automatically. No shop air is consumed when the booster is stalled.
