STA Series Air Driven Gas Booster
STA series air driven gas boosters are single acting model with single air drive head (except STA02 and STA05). For air drive pressure from 1 bar (14.5 psi) to 8 bar (116 psi). They should be prepressurized at inlet port so as to obtain required outlet pressure, which value will be variable for different requirement.
These boosters are ideal for increasing gas pressure, transferring high pressure gas, charging cylinders and scavenging. Key features include:
l Air driven - no electricity required
l No airline lubricator required
l Hydrocarbon free - separation between air and gas sections
l Pressures to 80Mpa (11,600 psi)
l Wide range of models with different ratios
l Built-in-cooling on most models
l Easy to install, operate and maintain
l Best price / performance ratio
l No heat, flame or spark risk and explosion proof
l Pump head fitted with exhaust cooling devices.
l All parts in contact with the gas are made of aluminium or stainless steel.
The boosters can be used for not only air or nitrogen, but also flammable and risk gases like hydrogen, oxygen and natural gas.
Air driven boosters are an efficient alternative instead of electrically driven products and can be used in explosion- proof areas.
Diameter of air drive plunger is 160mm, the drive air pressure is 3-8 bar.
