The curved face of the rotors engaged fully, thus contributing to
the formation of a hydrodynamic lubrication film, reducing the
contact zone of the lateral leakage, improve compressor efficiency;
as well as to improve the processing, test performance of the
rotor.
Oil separation system
LGCD Direct-driven Screw compressor up to 132 kW are equipped with external separators that can be changed in a simple spin-off/spin-on process. Larger units have an internal separator cartridge. Due to the excellent separation efficiency of the system as a whole, the compressors can be used in the pressure range of 5.0 to 15.0 bar. Special pressures on request.
The frequency converter minimises idle times and optimises supply with fluctuating compressed air requirements. Start-up peaks are avoided and the compressor’s delivery rate is controlled continuously – that saves electricity costs! The total costs for your compressed air supply are significantly reduced and investment costs are amortised in the shortest possible time.

Shanghai Rotorcomp Screw Compressor Co., Ltd
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.
