AquaGuard® Desiccant Breathers

Specifically designed for gearbox and pump applications where air flow is at a minimum, AquaGuard® desiccant breathers attack high humidity, keeping lube systems clean and dry. + MORE INFORMATION

  • Prevents pressure and temperature build-up
    • Overpressure bladder design
    • Unique dual check-valve system
  • Blocks the introduction of raw moisture during clean-up and wash-down operations
  • Suitable for 1 cfm applications
In addition, AquaGuard® desiccant breathers:
  • Hybrid technology breather for low-flow applications
  • Ideal for washdowns and high humidity areas
  • Desiccant, particulate filtration ensure incoming air is clean and dry
  • Expansion chamber system isolates lubes from extreme ambiant humidity
  • Check valves ensure no excess pressure/vacuum builds
Features:
  • Foam Pad
  • Patented Polyester Filter
  • Silica Gel/Desiccant
  • Expansion Chamber
  • Four Check Valves
  • Rugged polycarbonate body and nylon standpipe
  • Threaded inlet tube with o-ring
Applications:
  • Thermal expansion/ contraction only
  • High humidity
  • Gearboxes and other low flow applications
  • Pumps
  • Bearing houses
  • Storage drums, Totes
  • Washdown applications
  • Closed loop systems
