Breathe better with T.R.A.P Technology

Moisture meets its match with Donaldson’s T.R.A.P breather technology.

Donaldson T.R.A.P Breathers collect and eject moisture from your holding tank which means you wont need to change your breather as often due to water saturation unlike other desiccant filters.

How it works

T.R.A.P breathers from Donaldson can strip the moisture from intake air and remove it back into the atmosphere on the outflow cycle. This ultimately regenerates your breathers water holding capacity.

1. The circuit breaths in air containing moisture.
   
   

2. The breather then strips any moisture and particulate coming in, allowing only clean and dry air to enter the circuit.
   
   

3. During the exhalation cycle, the breather allows unrestricted airflow outwards.
   
   

4. The outflow of dry air picks up the moisture collected by breather and removes it, ultimately regenerating your breathers water holding capacity.

Thermally Reactive Advanced Protection (T.R.A.P.™)

Water always finds a way in to your hydraulic circuits and that’s why Donaldson developed T.R.A.P Breather technology, to stand guard over your systems.

Stop water before it gets in without restricting air flow and let your hydraulic / oil tanks breathe.

The benefits

Long lasting – extended life with moisture being released back out to the air with each cycle.

Effectiveness – Superior moisture blocking and particulate filtration.

Rugged design – robust housing protects filter media and withstands vibration, T.R.A.P is suitable for both stationary and mobile applications.

Maintenance Cost - increased service hours.
