Why Filter Compressed Air and Gases

 

Submicronic contaminants in compressed air systems can:

1.  plug orifices of sensitive

2.  pneumatic instrumentation

3.  wear out seals

4.  erode system components

5.  reduce the absorptive capacity of

6.  desiccant air/gas dehydrators

7.  foul heat transfer surfaces

8.  reduce air tool efficiency

 

The results include:

1.  product rejects

2.  lost production time

3.  increased maintenance costs

 

For example, trace amounts of submicronic oil can cause serious fish eye blemishing in automotive finishing operations. Water left in air lines can freeze during exposure to cold, blocking flow or rupturing pipes. Compressor lubricant not captured in a coalescing filter will eventually collect in pneumatic components, causing premature component repair or replacement. Environmental concerns will be raised if oily, compressed air is continually discharged into the atmosphere through a pneumatic muffler.

 

This filter housing cutaway depicts the coalescing process. Air enters the housing and flows through the filter media passing from the inside element surface to the outside.

 

In filter compresd air and gas systems, coalesced liquid collects in the housing where it is drained and clean air exits the housing through the outlet port.
