Compared with other technologies, this series of vacuum pumps can save about 50% of energy consumption. It is one of the permanent magnet variable frequency screw vacuum pumps with the best energy efficiency performance on the market at present. In contrast, the mechanical equipment of oil-lubricated rotary vane pump, water ring pump and other technologies has low efficiency and high cost. In vacuum applications, approximately 90% of the electrical energy is converted to thermal energy. The integrated energy recovery system of all series of screw vacuum pumps can convert 75% of the electric energy input into heat energy without any impact on the equipment. Through the effective use of energy recovery system, you will save a lot of energy costs and get a high return on investment.

KLS series oil-free screw vacuum pump is a dry vacuum pump with advanced technology independently developed by our company. Because the screw vacuum pump does not need oil lubrication or water sealing, and the pump cavity is completely free of oil, the screw vacuum pump has incomparable advantages compared with the traditional water ring vacuum pump, the rotary vane vacuum pump, the rotary piston vacuum pump, the reciprocating vacuum pump and the water jet vacuum pump, and has the advantages of energy saving, emission reduction and low cost. Carbon environmental protection is a new trend in the development of vacuum industry. Suitable for packaging, papermaking, CNC, plastics, glass, leather, foam, printing and dyeing, PVC pipes, bottles, wood processing and meat packaging and other applications.

The oil-free screw blower is mainly composed of a chassis, a main machine, a motor, an air filter, a silencer, an oil pump, an oil tank, an oil filter and the like. Performance Advantages of Coles Oil-free Screw Blower High standard oil-free compressed air with oil content of grade 0; Lubricating oil is not involved in the compression process to ensure that the compressed air does not contain lubricating oil; Special seal design to prevent lubricating oil from entering the compression chamber; Motor frequency control, intelligent matching speed, to ensure stable exhaust pressure; The motor is controlled by permanent magnet frequency conversion to improve energy saving effect.
