Over the past three years, a number of air screw compressors have been created with a capacity of 4 to 40 m3 / min and an overpressure of discharge of 0.7 ... 0.9 MPa. These compressors use a new profile of the rotor teeth, designed by OAO VNIIholodmash-Holding, taking into account modern trends.</p>screw and scroll compressorsrotorreciprocating compressorsвинтовые и спиральные компрессорыроторпоршневые компрессоры
