The AS-XXX Series Powerex Simplex Air
Compressors have been designed, bro-
ken-in and tested to meet the most
demanding specifications in the pneu-
matic climate control industry for low
oil carryover and long life.
All Powerex air compressors have reli-
able operation and feature high quality
construction and components. An
unloading feature is included on all
compressors to provide loadless start-
ing. Oil entrainment is minimized by
the use of lap joint piston rings, low
compressor speeds and a special lubri-
cating oil with a high flash point and
low carbon content.
All 1/2 through 10 hp models are also
equipped with an auxiliary cooling fan
and air control shroud to achieve low
head temperatures and further mini-
mize oil carryover.
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.
