Breathers

Des-Case hygroscopic breather elements are state-of-the-art in design and function, and are industry’s best choice for assuring maximum machine performance. Des-Case offers these cost-saving benefits:

• Elimination of water-contaminated oil which leads to additive stripping
• Elimination of rust-forming condensation
• Elimination of sludge deposits
• Less abrasive particles to prolong machine operating life
• Longer oil and oil filter life

Resilient Construction

Moisture and particulate accumulation are major factors of oil contamination in industrial equipment. Neglected, these detriments restrict equipment efficiency, causing machine downtime and significant expense in replacement oil, parts and repair labor.
Des-Case breathers incorporate a proven, field-tested design. They prevent water and contaminants from entering fluid reservoirs as differential pressures occur through thermal expansion and contraction of the fluid, or during the filling or emptying process.
Des-Case breathers utilize the entire area of the patented polyester filter media to remove solid particulate material as small as 3-microns. Accompanying water vapor is then removed by the desiccant agent. A final filter ensures that only clean dry air enters the system.

Unique Filtration Process

Every Des-Case desiccant breather is manufactured in a durable, shock-absorbing clear plastic casing with resilient qualities to withstand the customary abuse associated with heavy manufacturing equipment. The units are disposable, and are manufactured entirely of environmentally safe components.
Des-Case standard desiccant breathers are manufactured in three sizes, DC-2, DC-3, and DC-4 to accommodate different mounting space requirements. All three models are rated for 16 cfm of air in and out of the tank or reservoir (the equivalent of 120 gpm fluid level change in the tank).

Models, Accessories & Installation Methods

Des-Case standard disposable breathers retain particulate as small as 0.5-micron (73.5% efficiency) or 3-micron absolute, are rated for 16 cfm and feature a 1" threaded standpipe.

Des-Case desiccant breathers are designed for installation on most equipment regardless of location. For installation in difficult areas, Des-Case offers accessories enabling breather placement to be several feet away from an oil reservoir or gearbox.

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.
