Air driven gas booster Rugged, efficient Pressure range:1.6~80mpa Seven pressure ratios available Best price, high quality Air driven gas boosters are high pressure reciprocating pumps used for gases boosting, driven of compressed shop air. Sta series boosters are single acting, single air head driven type.(except model sta02 and sta05.They are double acting models).They have to be prepressurized at the inlet port so as to meet with the outlet pressure requirements, which value will be variable based on the permitted maximum outlet pressure. Sta series gas boosters are suitable for the oil free compression of air and industrial gases like nitrogen, helium as well as flammable and risk gases like hydrogen , oxygen and natural gas.Air drive pressure from 1bar(14.5psi.) to 8bar(116psi.). Provide for operating pressures up to 80mpa. As per buyer's requirment
