Descriptions

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 tempera- tures.

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.

Teflon® 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).

Installation

INSTALLATION SITE

1.The oilless compressor must be locat- ed in a clean, well lit and well venti- lated area.

2.The area should be free of excessive dust, toxic or flammable gases and moisture.

3.Never install the compressor where the ambient temperature is higher than 105o F or where humidity is high.

!DANGER

Breathable Air Warning

This compressor/pump is NOT equipped and should NOT be used “as is” to supply breathing quality air. For any application of air for human consumption, you must fit the compressor/pump with suitable in-line safety and alarm equipment. This additional equipment is necessary to properly filter and purify the air to meet minimal specifications for Grade D breathing as described in Compressed Gas Association Commodity Specification G 7.1 - 1966, OSHA 29 CFR 1910. 134, and/or Canadian Standards Associations (CSA).

DISCLAIMER OF WARRANTIES

In the event the compressor/pump is used for the purpose of breathing air application and proper in-line safety and alarm equipment is not simultaneously used, existing warranties are void, and Powerex disclaims any liability whatsoever for any loss, personal injury or damage.
