Low pressure screw air compressor directly outputs low pressure compressed air of suitable pressure to obtain the best exhaust capacity with less energy consumption. At the same time, the rotor clearance and the main engine shell are designed precisely, which changes the exhaust source and all the design of the main engine to meet the requirements of large flow and low pressure, such as to increase bearing seat. The low pressure screw air compressor also introduces part of the axial intake design, so that the effective length of the screw involved in compression can be fully used, while reducing the noise of the main engine, effectively reducing the radial unbalanced force, and prolonging the life of the main engine and bearing.

The inlet valve of low pressure screw air compressor avoids the shutdown air having reflux or injection. The design of large diameter and low pressure drop makes the inlet efficiency reach the optimal state, that is unloading without emptying, and thus effectively reduces energy consumption. The cooling area of oil-cooled and air-cooled coolers is increased by 50%, and the piezoresistivity of oil and air passages is reduced, so the energy consumption of the system is effectively reduced. The intelligent control system automatically adjusts the volume of exhaust according to the customer’s usage and reduces the waste of energy. For many brands of depressurization, they are energy saving, and in the meanwhile, they ensure that oil content is less than 1 ppm. Improve the yield of chemical fiber industry, keep the  gas source stable and clean, ensure that the sprayer nozzle does not take off the net, have solid mesh, good product quality and high price.
