5-15 HP Two-Stage Reciprocating Compressorsr

The two stage oil-free reciprocating compressors are Elgi's solutions to the increasing need by industries and research institutions for higher purity in compressed air applications.

"No oil in compressor is equal to no oil in output air from the compressor" Elgi oil-free compressors are engineered on this principle. Elgi has adapted a dry crankcase that is totally devoid of oil. The internal moving and friction parts of the compressor have been designed suitably to overcome the absence of lubricating oil. Sealed bearings have been used for crankshaft and connecting rods. Poly Tetra Fluoro Ethylene (PTFE) coated pistons and PTFE rings have been used to provide wear resistance.

Designed for industrial duty, the compressor is a perfect solution for applications where oil carried in air can affect the end product or downstream components through which air flows after the compressor. To the customer this means less expenditure on maintenance —elimination of expensive oil removal filters, frequent stoppages for oil top and oil fills in the crankcase.
