Des-Case Extreme Duty Breathers

The Des-Case Extreme Duty (XD) desiccant breather has excellent vibration and impact resistance, can withstand broad temperature ranges, has expansive chemical compatibility, and features quality check valve technology while still accommodating higher air flow. The Extreme Duty breather also has the best filter efficiency of any Des-Case breather―down to 0.3µ absolute (β0.3≥200).

• Excellent vibration and impact resistance
• Broad temperature range and chemical compatibility
• Quality check-valves isolate system while accommodating high air flow
• Filter efficiency down to 0.3μ (ß0.3≥200)
• Provides longer oil and filter life

Extreme Duty Breather Features

Quad Check Valves
Check-valves provide system pressurization, protecting system integrity and extending product life.

Filter Element
ePTFE filter removes airborne contamination to 0.3-micron absolute. Stops free water.

Water Vapor Adsorbent
Color-indicating silica gel adsorbs water from incoming air. Replace when color changes from blue to pink.

Filter Element
Second particulate filter element protects against migration of desiccant.

Visual Indicator
Windows on two sides of breather allow for easy monitoring of desiccant.

Rugged Housing
Constructed from a PC/PBT alloy that maximizes chemical compatibility at the surface and impact resistance at the core.

Foam Pad
Foam filter captures any oil mist and disperses incoming air evenly over filtration and drying areas.

Integrated Standpipe
Resilient construction provides durability and allows oil mist to coalesce and drain back into the reservoir.
