DONALDSON | TRAP Breather LED DN25 (1") P564669

The Thermally Reactive Advanced Protection (TRAP) Breather assembly protects the fluids in your storage tank from airborne particulate moisture contamination and ambient moisture. 

It combines a high capacity 3-micron air filter with a deliquescent breather than regenerates itself when air is expelled from the tank. This self-regenerating capability of the TRAP enables extended life and functionality. 

Keep your fluids clean and dry with a Donaldson TRAP Breather.
