Contamination Control

HydroGuard

The patented Hydroguard™ Breather is the ideal solution for the management of lubricant in:

  • Frequent wash-down applications
  • Frequent cycle applications
  • Applications in which the breather bladder can maintain a sealed system
  • High humidity environments where there are increased incidences of gearbox and lubricant failure due to moisture ingress
  • Low-flow applications
  • High-humidity applications

HOW IT WORKS…

As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate and the color-indicating silica gel extracts moisture. The bladder on the Hydroguard™ breather provides an area for the air to expand and contract as a result of temperature variations during steady-state operations. When air is expelled from the equipment headspace, the bladder expands and the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere. Once the bladder is filled with air and the pressure exceeds that of the breather, the check valves will open and the excess pressure will be released. The hydrophilic agent is partially reactivated by the dry air passing back through.

HYDROGUARD™ MODELS

 The Hydroguard Breathers handle air volume caused by thermal expansion and contraction only. The threaded standpipe design can easily be adapted to any size reservoir opening. Please see below for details on all Hydroguard™ Breather models.
