Donaldson Hydraulic T.R.A.P.
Breathers
Keep moisture and dirt OUT of your hydraulic reservoir with
Donaldson’s innovative new technology, the Thermally
Reactive Advanced Protection (T.R.A.P.™) breather! It
senses moisture and begins working faster and lasts longer
than desiccant breathers. This is an entirely new technology
that provides better protection for your oil or hydraulic
fluid.
T.R.A.P. Breather Technology from Donaldson®
- Reacts faster—Senses and begins removing moisture
at low 15% RELATIVE HUMIDITY. This
better accommodates the short cycles of hydraulic circuits.
- Lasts longer—Exhales moisture with every flow cycle,
regenerating its water-holding capacity.
- Signals change out—Indicates need for change out
with flashing red light
- Installs easily—Lightweight; simply hand tighten
- Adapts—Suits both mobile and industrial applications
Patented T.R.A.P. media regenerates its water-holding capacity,
which leads to longer service life.
Competitive testing revealed that T.R.A.P. breathers continued
performing beyond 3,000 cycles while silica gel breathers
significantly declined in efficiency at less than 2,000 cycles.

T.R.A.P. Breather … Moisture meets its match.
WATER MEENS TROUBLE and it has a way of sneaking into your
hydraulic circuits. Unless you have a Donaldson TRAP Breather
standing guard over your system.
NO moisture slips by Donaldson’s Thermally Reactive
Advanced Protection (T.R.A.P.). In fact, it removes moisture
at relative humidity levels as low as 15%! TRAP filtration
technology reacts instantly to thermal conditions, blocking
moisture completely.
T.R.A.P. Breathers from Donaldson are the ONLY breathers
on the market that literally strip moisture vapor from intake
air and exhale the moisture back to the atmosphere on the
outflow cycle. The filter continuously regenerates its water
holding capacity!
