BT Breathers with
T.R.A.P.® Technology
T.R.A.P.® Technology
Self-regenerating desiccant breathers with integrated 3 µm[C] particulate filtration. T.R.A.P.® (Thermally Reactive Advanced Protection) media uses your system's own heat cycles to regenerate moisture-adsorption capacity.
BT Breather with T.R.A.P.® Technology
Product Overview
BT Breathers combine moisture protection and particulate filtration in a single unit. The T.R.A.P.® (Thermally Reactive Advanced Protection) desiccant media regenerates its moisture-adsorption capacity using normal system heat cycles, extending service life beyond what traditional silica-gel breathers can deliver.
- T.R.A.P.® media regenerates moisture-adsorption capacity using system heat cycles
- Integrated 3 µm[C] particulate filtration at 97% capture efficiency
- Multiple sizes covering 3 cfm to 45 cfm airflow ranges
- NPT, BSPT, and SAE connection options for global fitment
- Optional electric LED saturation indicator on -DX models
- Replacement indicator kits available for field upgrades
