Donaldson T.R.A.P.™ Breathers – Clean, Dry Air for Your Storage Tanks
Contaminated air entering your bulk storage tanks can introduce moisture, dust, and airborne particulates, which degrade fluid quality and shorten equipment life. At Fleetcare, we offer Donaldson T.R.A.P.™ (Thermally Reactive Advanced Protection) Breathers—a smarter, dual-function solution that removes moisture and particulates from incoming air while expelling moisture vapor on the outbound air flow.
Whether you’re storing diesel, lubricants, or hydraulic oils, the T.R.A.P.™ breather keeps your fluids clean, dry, and ready for use.
Why Use Donaldson T.R.A.P.™ Breathers on Storage Tanks?
Traditional tank vents allow ambient air—often contaminated with humidity, dust, or exhaust particles—to enter your tanks during fluid drawdown. This introduces water and contaminants that:
-
- Accelerate fluid degradation
-
- Promote microbial growth in diesel
-
- Increase wear on machinery
-
- Lead to unplanned maintenance and downtime

- Lead to unplanned maintenance and downtime
