Heavy Duty Applications

Typical Applications

  • Heavy Duty Off-Road Equipment
  • Mobile Heavy Equipment
  • High Temperatures
  • Corrosive Chemicals

M-Series breathers are designed from heavy-duty materials capable of handling the requirements of the most severe environments. They replace the standard breather cap or vent tube on fuel tanks and fluid reservoirs. Pipe threads on the bottom standpipe make the units easy to install in moments.

All M-Series designs have 2 micron pleated filters and silica gel bags that are easily replaced. They also feature the proprietary Splash Sentry™, which prevents foaming or splashing fluids from entering the breather during normal operating conditions.
