The Moisture Minder® I piston drain is pneumatically operated and requires no electricity. It does not waste expensive compressed air like solenoid drains, float drains, or diaphragm drains. This drain is operated by an air pilot or pressure signal from the compressor unloader. The Moisture Minder® cycles each time the compressor starts and stops, using the unloader to operate the drain. It will handle compressors up to 30 HP, although it can be used in compressors up to 200 Hp when used with a DrainMinder® controller.

How does the Moisture Minder® work

As the piston moves forward, it closes the intermediate chamber and opens the ball valve. When the ball valve is open the condensed moisture and oil rush into the intermediate chamber and the excess into the reservoir, compressing the atmospheric air contained in the reservoir. As the piston returns, the ball valve closes and opens the exhaust port. The condensation is then expelled automatically out of the drain. Construction: Anodized aircraft aluminum Stainless steel ball, piston rod, springs, & strainer, retainer, and screen Teflon™ and Viton™ seals Absolutely unbeatable in applications where oil is an issue.
