Compressor Airend
A standard C-Face mounted motor ensures that the motor and compressor will be properly aligned when the compressor leaves our factory… and stays that way.
The integrated mounting flange allows access for coupling maintenance. The flexible dropout coupling can be replaced without removing the motor!
A cartridge-style, triple-lip seal arrangement ensures the oil stays in and contaminants stay out.
Designed to be direct driven
with no gears or belts involved. 3 1 4 2
