Diaphragm Compressors

Complete gas tightness, Oil-free operation as the diaphragm itself requires no lubrication
Dryness of the gas is not a concern as there are no piston rings, Pressure ratio of 1:20 is achievable in a single stage, as temperature rise is low since the compressor does not operate close to isentropic adiabatic compression, allowing a greater variation in suction and discharge pressures, Two stages , duplex or special design, Ability to handle radioactive, toxic, explosive and corrosive gases, To achieve higher flow an oil free screw compressor can be offered as a feeder
Capacity control is achieved by inlet pressure variation, by-pass, variable frequency drive or combination
