Contamination control
October 1st 2007

In any enclosed reservoir containing fluids or semi-solids, air is breathed in and out as the fluid level changes or as thermal expansion and contraction occurs.

Contamination of fluids from the incoming air is the primary cause of wear and lubricant failure in industrial equipment. RW Greeff's new Air Sentry breathers replace the standard breather cap or vent tube on a tank or reservoir.They are said to be easy to install using one of several adapters designed for many different applications.

When the fluid in a system is lowered or pressure changes occur, air is drawn through the openings in the breather cap.Air first passes though a fine two micron solid particulate filter followed by a diffuser to ensure maximum effectiveness in the subsequent silica gel chamber that removes water vapour.

After being dried, the air passes through a second two micron solid particulate filter before entering the reservoir clean and dry.
