Donaldson P565857 - TRAP Breather

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.

• 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.
