The global demand for rotary scroll compressor is expected to cross $14 Billion by 2026. In the past 10 years, they have become a major player in compressed air, previously dominated by reciprocating screw compressors. The compressors are used in variety of applications including chemical, pharmaceutical, food & beverage, laboratory, and medical, and provides benefits such as improved efficiency, fewer moving parts, smooth and quiet operation, and a smaller and cleaner work space. 

A scroll compressor works in a circular motion as opposed to an up-and-down piston action. Its design uses two interleaving scrolls (one part that moves in a circle while the other is stationary) to pump, compress or pressurize fluids such as liquids and gases.

Scroll compressors have two leakage paths, i.e., axial and radial leakage. Of these leakage paths, axial leakage is quite serious since it affects the efficiency of the compressor. To prevent this axial leakage, scroll compressor manufacturers use tip seals that are placed into grooves on the tips of both spirals.

For oil-free scroll compressors, they face a unique challenge as they cannot use any type of lubrication. Due to this non-lubrication environment, temperature, friction and wear of the tip seal increases, which lowers the efficiency of the compressor.

Omniseal Solutions™ has developed Rulon^® fluoropolymer compounds especially for oil-free scroll compressors. Trials have revealed that the material wear in our compounds is approximately one half (1/2) compared to existing materials available in the market. Due to this lower wear and less friction, the life of the tip seal is significantly enhanced thereby increasing time between change over. 

• Low material wear, less friction, high life

• Custom designed, reliable solution

• Low maintenance costs
