Industrial compressor
A screw compressor consists of two helical rotors male and female rotating within a cylindrical housing. These rotors operate with a manufacturing precision of 10 microns and an air gap of 0.1 mm. Their typical compression ratio is between 7 and 15 with a volumetric flow from 100 to 20,000 liters per minute. Rotors are made from forged steel coated with PTFE or DLC to reduce friction. Operating speed typically ranges from 1500 to 3600 RPM with volumetric efficiency over 90%. A VSD Variable Speed Drive control system reduces energy consumption by up to 30%.
The compressor structure includes an intake filter, compression unit, oil separator, and cooler. In oil-injected models, dedicated ISO-VG 100 oil performs cooling, lubrication, and sealing. Operating temperature in oil-injected models is controlled between 70 and 90°C. Generated noise level at one meter distance is often below 70 dB. A multi-stage oil separation system reduces oil carry-over to less than 3 ppm. These compressors are ideal for continuous operation in manufacturing industries and large workshops.
