Donaldson Trap Filter
Bulk Tank Breather & Moisture Prevention – Donaldson DFF0078
Filter Breather TRAP 1.5” BSP Male
TRAP Breathers reduce dirt and air-borne moisture (humidity) from entering hydraulic and other fluid reservoirs. With models available for both stationary and mobile applications, they provide faster acting protection and greater capacity than silica gel breathers.
The dual protection TRAP has a self-regenerative outer media that reduces airborne moisture down to 15% relative humidity, while the high capacity inner media is 97% efficient on particles down to 3µm.

How a T.R.A.P. Breather works:
Intake Cycle (Inhalation)
1. The circuit “breathes in” air containing moisture vapor.
2. The T.R.A.P. breather strips moisture and particulate from the incoming air, allowing only clean, dry air to enter the circuit.
Outflow Cycle (Exhalation)
3. During the “exhalation” cycle, the T.R.A.P. breather allows unrestricted airflow outward.
4. The outflow of dry air picks up the moisture collected and dries the media.
