T.R.A.P. (Thermally Reactive Advanced Protection) breathers provide fast-acting protection against airborne moisture and particulate contamination. T.R.A.P technology strips moisture vapor from intake air and expels the moisture back to the atmosphere. Moisture is prevented from entering and is actually "pumped" out with each flow cycle. The media regenerates its water-holding capacity, which leads to longer service life – 3 to 4 times the life of conventional desiccant breathers.
