Super Energy Saving 55kw 75HP Oil Free Screw Type Air Compressor Manufacturer

Product Description

     Water lubricated oil-free screw air compressor has achieved the advantages of low-temperature compression, low speed operation, simply structure and convenient maintenance, so the manitenance costs are greatly reduced.

      Our company provides 100% oil free water lubricated screw air compressors, as we use the water as the lubricant in the air system, so oil free water lubricated screw air compressors are friendly to the environment, without any harmful emissions. Widely used in industrial production such as pharmaceuticals, electronics, chemicals, microbial fermentation, blow molding, etc
Product Features
        In pharmaceutical, electronic, chemical, microbial fermentation, blow moulding, pressure detection and other industrial production, there are many medium-pressure compressed air to be used to 1.6-4.0 MPa in power plants, naval ships, national defense facilities. At present, piston air compressors are mostly used at home and abroad, while piston air compressors are characterized by large vibration, high noise, large leakage and short service life, so their efficiency is very low and the same work is done. The medium pressure oil-free screw machine has compact structure, high working efficiency, low noise, low vibration, easy maintenance, low operating cost and good air quality. At the same time, the series of machines are controlled by micro-computer system. The whole machine has multiple protective performance of pressure, temperature and overload energy.
1.Constant pressure control: high-precision constant pressure control with a pressure fluctuation range within0.01MPa.
2. Variable frequency soft start: remove peak current during starting, avoid the power grid impact, prevent the current impact through gradual speed regulation and improve flexibility; 
3.No idling: prevent idling of the compressor during running and reduce invalid energy consumption;
3.High performance vector control: low-frequency starting provides a large torque and a low running current, ensuring to get a reasonable torque to drive the air compressor to run stably with the minimum temperature rise of the motor within a wide speed range;

Water-lubricated Oil-free Compressor Airend The water lubricated screw air end adopts PEEK (ultra high strength and wear-resistant molecular material) door rotor, aerospace grade all stainless steel rotor, and a new production process, demanding perfection.

Main Rotor Structure The main rotor adopts a single screw structure, and the screw meshes with the left and right star wheels to compress to ensure the mechanical balance and achieve the effects of low vibration and low noise under pressure.

Direct Drive Electric Motor The main airend is connected with the output shaft of electric motor through an elastic coupling, making the transmission loss almost zero.

Only Need Water to lubricate Water lubricated oil-free screw compressors use water as a sealing medium and lubrication, with low operating speed and temperature. There is no lubricating oil in the system, which can ensure that the compressed air discharged is 100% clean and oil-free.

Simple system process The entire system consists of stainless steel components and control components that meet food grade standards, including corrosion-resistant material components such as the compressor air end, separation tank, connectors, filtering components, water level controller, etc., with less maintenance consumables and a simple design
