Passat (‘G’) Series Compressor/Boosters have been engineered with a gastight crankcase (‘special’ double crankshaft seals and jointing) to prevent gas leakage, and are oil-lubricated, single acting reciprocating compressors with air-cooling. The ‘G’ series compressor/boosters are similar in performance to the ‘H’ series but are designed for noble gases such as Helium and Argon, and hazardous gases such as Carbon Monoxide and Natural Gas. Oil pressure fed to the crankshaft bearings and oil splash for compression, combined with Sauer regulated oil injection system for the final piston plunger design, ensures high reliability. The ability to handle elevated suction pressure for both noble or hazardous gases, gives enhanced performance to final pressures between 290 – 580 PSI reliably in three stages and from 1450 – 5075 PSI in four stages within the gas flow rate range of 5.9 – 236 SCFM. Models Available in ATEX Version: WP156L, WP276L, WP316L
