A compressor is a mechanical device that increases the pressure of air by reducing its volume. It takes air from one end, compresses this air to high pressure and then delivers it at the other end for various applications or mechanical work. Industrial air compressors are used in various industries including general industrial, chemicals, food and beverage, oil and gas, power generation and life science.

The different compressor types are rotary, reciprocating and centrifugal. Rotary compressors constitute almost 60% of the overall market.


The compressor market is changing with new requirements requiring lip seal life of over 45,000 hours. Additionally, new operating pressure has increased two to three times the previous normal operating pressure. Leakage can no longer be tolerated.

Omniseal® 80 Rotary Lip Seal


Omniseal Solutions™ designed its first lip seal in the 1980s and was one of the first businesses to support industrial compressor customers. In the past 50 years, we have manufactured over a million lip seals. These sealing solutions offer tight leakage control and the ability to run at 1,000 to 6,000 RPM with many types of lubricants and over extended periods (15,000 hours) to reduce warranty claims. We can produce shaft seals ranging from 0.500 inch to 6.000 inch (13 mm to 150 mm) in diameter for this industry.

Lip seals are widely used in rotary screw compressors to prevent leakage of lubricating oil and working medium, i.e., air. The shaft seal leakage / failure to seal can increase energy consumption of the compressor, resulting in downtime. To help customers stay competitive, we made major changes in the lip seal design and can now offer several special designs that provide compressor manufacturers an expected 45,000 hours of life without replacement.

In the past 50 years, we have manufactured over a million lip seals ... each one saving cost, keeping maintenance low and reducing downtime.
