I will put these units head to head with any other air compressor built , I feel we have the best unit out there.  Give me A call let’s talk.

 Units are extremely quiet, run very cool even in the nastiest environments. 

  If you are having problems keeping your air compressor from overheating and shutting down give one of these A try.

Large low speed airend, ( not high speed encapsulated airends used by others, this is much cheaper way, short life)

Premium efficient  Motors are Totally enclosed fan cooled  

 (Not open motor used by others, short life cheaper way)

Large drop in air oil separator for long life less maintenance cost  ( not small spin on separators used by others cheaper way short life )

Separate oil sump for the large oil capacity

All air and oil lines are stainless steel and coated lines  (not hose, used by others, cheaper up front, costly to replace. Hose will fail and leak)
