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

Des-Case HydroGuard® breathers uniquely feature an expansion chamber and internal check valves that create a nearly-sealed system. Designed specifically for steady-state operations with minimal temperature fluctuations, these breathers provide excellent protection in continuous duty applications.

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

As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate while the color-indicating silica gel extracts moisture. The diaphragm allows for expansion/contraction of the air within the casing as a result of temperature variations during steady-state operations. When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere.
