The gas booster packages compress breathing air, argon, helium, nitrogen, oxygen and all other dry non-corrosive gases up to 414 bar (oxygenis limited to 311 bar) from as low as 3.5 bar. They are suitable for maximizing the use of gas in storage cylinders which results in an increase in the number of complete fills per storage cylinder. Fill times are reduced by eliminating the need to cascade storage cylinders. Its two-stage design uses NO Belts or Pulleys, making it the quietest electrically operated booster in its class; only 60dB.
