RL400S Air Booster and Systems

4 to 1 Boost Ratio, 0-1.3 scfm flowrate

Our line of compact, air-driven, air pressure booster systems require no cooling water, lubrication or electricity. These boosters can deliver flowrates from zero to the values shown in the table below and provide pressure boost ratios from zero to 4:1. The integral pressure regulator is used to set the maximum discharge pressure desired. The booster will maintain this pressure regardless of fluctuations in supply pressure. When there is no demand for high pressure air, the booster stalls and consumes no energy. It restarts automatically when there is demand.
