10 to 1 Boost Ratio
This air 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 1.25 inch diameter boost cylinder. The air piston reciprocates automatically and drives the boost piston.The maximum discharge pressure is equal to ten times the shop air pressure. The table below 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 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.
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 TeflonŽ piston seals and rod seals. It requires no electricity, cooling water, or air-line lubricator and is explosionproof.
