Technology #### **Self-Regenerating Moisture and Particulate Breathers** Protect your uptime, critical hydraulic & lube assets and fluid life. Donaldson Hy-Pro Thermally Reactive Advanced Protection (T.R.A.P) breathers are critical in Donaldson Hy-Pro’s Total System Cleanliness approach as a barrier preventing airborne particles and water from entering reservoirs and gearboxes. Unlike traditional dessicant breathers, T.R.A.P breathers can self-regenerate their water-holding capacity, extending the life of the breather and lowering the total cost of ownership. ![T.R.A.P.
