T.R.A.P.™ Breathers


Donaldson™ breathers will collect and expel the moisture out of reservoirs. This means you won’t have to change the breather due to water saturation… unlike desiccant filters which will require frequent change-out.

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

Superior Moisture Blocking

Advanced Particulate Filtration and Oil Mist Control

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

Water has a way of entering into your hydraulic circuits. Unless you have a Donaldson T.R.A.P. breather standing guard over your system, this process will be not be avoidable.

Moisture is blocked by Donaldson’s T.R.A.P. breather. In fact, the moisture removed is relative to humidity levels as low as 15%. The unique T.R.A.P. filtration technology will react instantly to changes in thermal conditions. This ensures that moisture is blocked out.

T.R.A.P. breathers will strip moisture vapor from intake air. This moisture is then released back into the atmosphere from the outflow cycle. The filter will continuously regenerate its water holding capacity. T.R.A.P. breathers will expel the moisture back out. Therefore, eliminating the requirement to change the breather due to water saturation … unlike desiccant filters that will require frequent change-out. T.R.A.P. breathers will not only protect against moisture, but will also provide advanced particulate filtration.

Allow your hydraulic and lube oil reservoirs to breathe by using the TRAP water method, whilst ensuring air flow is not restricted.
