Since 1981, Air System Products, Inc. has been manufacturing efficient, reliable, cost effective products and systems. Our valued reputation has evolved with the continuous introduction of reliable and innovative products such as the Posi-Drain and the Posi-Zorb.

Our customers have known for years the rugged
reliability of the Posi-Drains proprietary "Posi-Valve";
without question the best timer drain in the industry.
The Posi-Zorb is our latest product introduction and,
again, the best in its class of Oil Water Separators.
The Posi-Zorb can handle multiple lubricant applications
and was developed specifically for the hard to separate Poly-Glycol's.
