All of our LGFD air screw compressors have special Drives and electrics system that is almost loss-free power transmission guarantees reliable, high-performance compressor operation. The regular maintenance requirement is reduced to lubrication of the motor.

The working process of the twin-screw compressor: the motor drives the main rotor through the coupling, the speed increasing gear or the belt. Since the two rotors mesh with each other, the main rotor directly drives the auxiliary rotor to rotate together.

Under the relative negative pressure, the air is sucked in. Under the action of the tooth peak and the tooth groove, the gas is transported and compressed, and when the rotor meshing surface is turned into communication with the exhaust port of the casing, the compressed gas begins to be discharged.

Shanghai Rotorcomp Screw Compressor Co., Ltd  founded in 1999, our company was a manufacturer of piston air compressors from 1985-1999. After 2000 our company headquarters moved to the international metropolis Shanghai and focused on screw air compressors, pressure vessel, refrigeration dryer, adsorption dryer and air filters with the support of Rotorcomp Verdichter Gmbh in German.

Shanghai Rotorcomp Screw Compressor Co. Ltd., Shanghai Ziqi Container Co.Ltd. have been cooperated with 2010 Beijing Nankou Railway Transit Machinery Co. Ltd., which belongs to China CNR Corporation Limited, as the strategic cooperation partner.

The Beijing Nankou company has processing equipment more than 100 sets, including large-scale precision equipment 90 sets and imported equipment 70 sets. Such as Hardinge double-ended grinder, Toshiba horizontal machining center, BW CNC vertical and horizontal machining center, Holroyd rotor profile grinder and Zeiss 3D measuring machine.

From 2017, we successfully develop the new generation oil-free air compressors with the ISO9001 certificate, ISO14001 certificate, energy-saving product certificate, OSHAS (Occupation Safety and Health management System) certificate, vonTUV certificate and CE Certificate. According to the Standard European Din40080, our air end and air compressors have won the praises of the customers over 45 countries worldwide.

Followed the principle and policy of " First-class Quality, First-class Service" Shanghai Rotorcomp insists on improving ourselves into a first-class supplier for the air compressor.
