Non Lubricated Compressors

where high pressure purity is required, as instrumentation air systems,non lubricated compressor should be used or consider.

The reciprocating compressor is available as a non lubricated model with carbon or Teflon rings.

new filtering problems may arise due to the type of oilless design used, such as carbon dust from worn carbon rings in the compressor.

also, multistaging may be required to attend a desired pressure due to temperature limitation.

Rotary liquid piston and centrifugal compressors eliminate the need for lubricating oil or oilless design since no internal lubrication is required on either type.

initial cost of the liquid piston compressor is higher but is offset by reduced maintenance cost.

 With water as a ceiling medium no after cooler is needed to remove the heat of compression or foreign matter which may be present in the incoming air.

This non lubricated Teflon ring allows reciprocating compressor to be operated without lubrication that presents filtering problem to instrumentation Air systems.

The  rotary liquid piston is another type oilless compressor. initially cost relatively high , but it is characterized by low maintenance cost.

the compressed air efficiently low and the  air delivered  to the dryers or distribution lines can be maintained about the dew point, thus eliminating moisture deposits in these lines.
