DONALDSON Filter TRAP Breather - DN20 (3/4") BSP Male

FILTER DONALDSON TRAP Breather DN20 (3/4") BSP Male

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.

Applications

• Designed for both mobile and stationary reservoir breather applications.

• Provide fast-acting protection for hydraulic reservoirs against airborne moisture and particulate contamination
• Moisture is prevented from entering and is actually “pumped" out with each flow cycle
• Regenerates its water-holding capacity, which leads to longer service life – 3 to 4 times the life of conventional desiccant breathers
• Electronic Indicator actuated by pressure differential, flashes red to indicate changeout is needed
• Mechanical indicator kits: highly visible, bright red band shows when restriction limit is reached
• Oil splash and mist containment keeps oil inside reservoir
• Easy to install, simply hand tighten
• Lightweight
• Rugged, durable design
• Robust housing protects media
• Withstands high vibration, suitable for stationary and mobile applications
