Maximator US Gas Boosters

Maximator US Gas Boosters are the gold standard of air driven compressors. Suitable for oil free compression of air, industrial gases like Argon, Helium, Hydrogen and Nitrogen. Air driven boosters are an efficient alternative instead of electrically driven compressors and can be used in explosion proof areas.

How they work 

The Maximator US boosters’ operating principle is similar to a pressure intensifier. A large air piston is charged with low pressure (air piston (3)) and works on a small area with high pressure (hp piston (2)). Continuous operation is achieved by a pilot operated 4/2 way valve (spool (4)). The spool leads the drive air alternately on the upper and bottom surface of the air piston.

Applications

With many pressure rations and options available we can match the optimum booster for different applications. Single Stage, Double Acting, Two Stage or a combination of models can be used to achieve different operating pressure and flow rates. Contact our team of engineers today to help with your application.

  • Pressure test with gas
  • Gas transfer
  • Gas recovery
  • Charging of nitrogen accumulators
  • Supply for isolating gas systems
  • Gas assisted injection moulding
  • CO2 foaming
  • Transfer of oxygen cylinders
  • Charging of breathing air bottles
  • Leak test

The spool is piloted through two 2/2 way valves (pilot valves (7)) which are mechanically actuated through the air piston in its end positions. The pilot valves charge and discharge the spool chamber. The hp piston supported by the check valves (inlet check valve and outlet check valve (1)) delivers the flow.

The outlet pressure is directly related to the set air drive pressure. According to the formulas indicated in the table with technical features of the boosters, the static end pressure can be calculated. At this pressure a force balance between drive section and gas section is achieved. The booster stalls when this end pressure is reached, and does not consume any further air.

A pressure drop at the high pressure side or a pressure increase at the drive side starts the booster automatically until the force balance is achieved again. Additionally the MAXIMATOR boosters can be switched on and off automatically through MAXIMATOR air pilot switches, contact gauges or external control devices
