ABSTRACT:
A gas filtration system is provided for coolant systems for dynamoelectric machines which utilizes differential pressures within the machine to induce a gas flow through the system. Valves are provided to balance dual inlet flows and the filtration system utilizes an air filter, coalescing filters and gaseous containment filter in its preferred embodiment. The filtration avoids the need for additional pumping by disposing its filtering means between and in fluid communication with two or more zones having different gas pressures.
