Positive displacement roots blower, from Climate Energy Sdn Bhd, is designed specially for methane gas with CORRGARD coating.
Two specially designed figure-eight impellers turn in opposite directions within a machined housing, transferring a constant volume of air or gas from the inlet to the discharge with every rotation of the blower drive shaft. No lubrication within the cylinder is required as the rotating components are held in close tolerance to each other and do not make contact. The impeller positioning is maintained by precision timing gears affixed to each impeller shaft. All essential gear and bearing lubrication occurs externally to the cylinder assuring clean, oil-free gas delivery under all operating conditions. Compression occurs after the gas leaves the blower and encounters system resistance in performing its intended work.
