Ventguard Breather Filter 1" Multi-Fit (NPT, BSPT, NPSM)

Des-Case VentGuard™ breathers have check-valve technology that isolates the system and only ‘breathes’ when necessary, making them an ideal solution that protect low-flow applications with intermittent operations. Check valves provide slight system pressurization that allows for controlled breathing without excessive pressure build-up. The system breathes only when pressured to do so, and then the air is cleaned and dried before it is introduced into the system, ensuring a clean, dry headspace. This control mechanism also prevents premature saturation of the silica gel and extends breather life, a problem not as easily tackled by standard desiccant breathers exposed to extreme moisture.

Benefits

• Removes moisture in the headspace of equipment
• Eliminates rust-forming condensation
• Prevents sludge deposits and water-contaminated oil
• Prevents contamination ingress
• Provides longer lubricant life
• Reduces wear and tear on equipment, prolongs life

How it works
Check-valves on the bottom of the unit isolate the system until equipment needs to breathe. As air is drawn into equipment through the breather, the layered filter elements remove particulate while the desiccant beads strip harmful moisture. While in service or during shutdown, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.
