Description
GENERAL
Powerex utilizes cutting-edge compressor technology
to provide the most advanced oilless reciprocating air
compressor in the industry. The Powerex reciprocating
compressor is available in single and two stage models.
Continuously lubricated, sealed bearings provide oil-free
compressed air and long compressor life. The onboard fan,
finned flywheel and temperature reducing composite piston
create lower operating temperatures.
DRY TYPE INLET FILTER
The inlet filter on the oilless compressor assures 99% of
particulate free air, down to 10 micron, is admitted to the
unit. Change every 2500 hours or more often in dirty locations
(See Figure 5).
PISTON AND PISTON RINGS
The Powerex oilless reciprocating compressor pistons are
made of a high-strength, self-lubricating composite using the
most advanced technology available. These heat reducing
pistons eliminate the effect of excessive grease leakage at
the wrist pin bearing. PTFE rings reduce wear and provide
self lubrication. Piston rings should be replaced every 10,000
hours of operation (See Figure 12).
BEARING REGREASE
The wrist pin bearings of the OPS and OPT oilless compressors
are needle bearings protected by two outer lip seals. This
needle bearing becomes impacted and requires regreasing at
5,000 hours (See Figure 15).
BEARING SEALS
The wrist pin bearing lip seals prevent the lubricating grease
from leaking from the bearing area. The two lip seals on each
connecting rod require replacement every 10,000 hours (See
Figure 16-22 or page 9).
