DBE Desiccant Air Breather

The DBE Desiccant Air Breather is tested using the latest ISO and NFPA test procedures.It is subjected to cyclic pressure to verify rated fatigue and burst pressures per NFPA Standard T2.6.1. Statistically sampled elements are tested to ensure fabrication integrity in the manufacturing process. It is also tested for efficiency and dirt-holding capacity in a multi-pass test stand, equipped with in-line particle counting capabilities, which are calibrated to ISO standards.

Application Example:

Problem: Difficult to access hydraulic tanks are located in damp environments and present significant challenges to access and change breathers.

Solution: The DBE has 4 check valves so only air entering passes over the dual-stage desiccant, effectively increasing moisture capacity of the breather in the same space. The DBE also has a 2 micron element to eliminate particulate ingression into the system.
