Volumetric air compressor energy efficiency rating released by national standards

Recently, the China National Standardization Administration (SAC) issued the national standard "Limited value of energy efficiency and energy efficiency rating of positive displacement air compressors".

This standard specifies the energy efficiency limit value of the volumetric air compressor, target energy efficiency limit value, energy conservation evaluation value, test method and inspection rules.

This standard applies to direct-coupled portable reciprocating piston air compressors, miniature reciprocating piston air compressors, all-oil-free reciprocating piston air compressors, commonly used fixed reciprocating piston air compressors, general oil-injected screw air compressors, general Single-screw air compressor with oil injection and general air-slide vane air compressor.
