Several common classification of oil-free air compressor

General oil-free air compressor is roughly divided into: water lubrication type, dry grinding type, reciprocating type, these three.

1. Water-lubricated air compressor

because the oil-free air compressor uses stainless steel and porcelain composite motor rotor, its driving force rolling bearing is completely oil-free. And because sprinkling water can reduce the speed ratio of machinery and equipment, the volumetric capacity of water lubrication without oil is high.

2. Dry grinding air compressor

when the dry grinding oil-free air compressor is in operation, its screw motor rotor compresses the gas by rapidly rising. The screw of the dry grinding oil-free air compressor is sprayed with resin components to maintain the screw from damage during rapid friction.

3. Reciprocating air compressor

small reciprocating oil-free air compressor motor single-axis drive, symmetry throughout the mechanical system. The double-shaft and two-cylinder structure of the reciprocating oil-free air compressor can make the air flow speed of the equipment within the rated range, which is twice that of a single cylinder, thus solving the vibration and noise of the double-cylinder refrigeration compressor.

Oil-free air compressor is a good performance of the air compressor, its classification as above. Naturally, the demand for oil-free air compressors in different fields will also vary, which can be selected according to the production and manufacturing situation.
