Electronic Indicator

Actuated by pressure differential, flashes red to indicate change out is needed. Indicator setting, 1 psid (6.9kPa). Indicator power source: 3V lithium battery CR2032.

Moisture Meets It's Match

Donaldson T.R.A.P.™ breathers collect and expel moisture out of tanks and reservoirs. This means you won’t need to change the breather due to water saturation, unlike desiccant filters which require frequent change-out.

Donaldson TRAP water and particulate before it gets in without restricting air flow − letting your reservoirs breathe easy.

How It Works

T.R.A.P.™ breathers from Donaldson are the only breathers on the market that literally strip moisture vapour from intake air and expel the moisture back to the atmosphere on the outflow cycle. The filter continuously regenerates its water holding capacity!

1. The circuit “breathes in” air containing moisture vapour.
2. The T.R.A.P. breather strips moisture and particulate from the incoming air, allowing only clean, dry air to enter the circuit.
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 by the T.R.A.P breather during intake, and “blows it back out” – fully regenerating the T.R.A.P breather’s water-holding capacity.

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

Water has a way of sneaking into your storage tanks / hydraulic circuits − unless you have a Donaldson T.R.A.P. breather standing guard over your system.

Donaldson’s T.R.A.P. breather removes moisture at relative humidity levels as low as 15%. T.R.A.P. filtration technology reacts instantly to changes in thermal conditions − blocking moisture.

T.R.A.P. breathers strip moisture vapour from intake air and release it back into the atmosphere on the outflow cycle. The filter continuously regenerates its water holding capacity. T.R.A.P. breathers expel the moisture back out, eliminating the need to change the breather due to water saturation - unlike desiccant filters that require frequent change-out. T.R.A.P. breathers not only protect against moisture but also provide advanced particulate filtration.

TRAP water before it gets in without restricting air flow, letting your hydraulic and lube oil reservoirs BREATHE.
