How it Separates Oil and Water from Compressed Air System Drains

The Posi-Zorb is designed specifically to ensure uninterrupted service and to extend the life of the filter module. The filter module contains proprietary media that selectively removes emulsified oils and may hold up to four times the amount of oil compared to standard activated carbon. The unit continues to function even in the event of upset conditions. The system only operates when the level of condensate rises. The unit also enables easy disposal. Once the filter media is saturated, the modules are simple to replace and there are no messy bags to handle. The modules are entirely self-contained and permit ease of installation and replacement.

*The maximum CFM capacity is based on polyglycol. Ratings listed may be increased by 25% if a refrigerated air dryer is not used. 
Not recommended for silicone-based lubricants. 
A PZM Filter Module could last 12 months in a Rotary Screw application. However, filter life may be less due to lubricant, compressor type, and maintenance.
