Compressed air drives large area end pistons and small area end gets high pressure gas output. Output pressure: up to 2690bar (269MPa), with oxygen up to 5000psi (34.5MPa). The gas booster pump series is the secondary booster pump, which can increase the extremely low pressure gas to a high pressure. The driving pressure is no more than 7bar. The pressure range of the gas input port is 0.5-10bar, and the maximum can be increased to 90Mpa. This series of pumps are the same as N series, the whole pump is made of aluminum alloy and stainless steel. In the gas-drive part of the pump, the series needs to be lubricated with a lubricating gas for sealing and other internal parts. The driving piston of the series pumps is 160mm in diameter.
