Description
The AS Series Powerex Simplex Air Compressors have been
designed, broken-in and tested to meet the most demanding
specifi cations in the pneumatic climate control industry for
low oil carryover and long life.
All Powerex air compressors have reliable operation and
feature high quality construction and components. An
unloading feature is included on all compressors to provide
loadless starting. Oil entrainment is minimized by the use of
lap joint piston rings, low compressor speeds and a special
lubricating oil with a high fl ash point and low carbon
content.
Powerex compressor motors are NEMA Class B design. Single-
phase motors have built-in overload protection and a DPST
disconnect switch. Three-phase motors require a manual or
magnetic starter and three overload heater coils which may
be ordered as a factory mounted and wired option.
