Sections: Rotary Positive Compressors

Companies in this section manufacture compressors and vacuum pumps which operate on several different principles, although all employ positive displacement and rotary motion. Included among these products are rotary positive displacement compressors greater than 30 psig discharge pressure and vacuum pumps that develop vacuum over 28” Hg. Such compressors may be oil free, forced-feed lubricated, or liquid injected, including, but not limited to sliding vane, lobe-type, liquid piston and helical screw. These compressors are stationary type or transportable (as distinct from engine driven portable compressors). In single and multistage configurations, these compressors are used in a wide variety of applications.
