High Vibration Applications

Typical Applications

  • Cranes
  • Railroad Maintenance of
    Way Equipment
  • Farm Implements
  • Construction Vehicles
  • Off-Road Trucks

Most heavy equipment - productive and on the move - is outfitted with hydraulic fluid tanks or reservoirs which breathe in the dirty outside air.

R-Series breathers are ideal for these high vibration, mobile applications, including off-road, construction and farm vehicles. R-Series desiccant breathers are easily mounted in place of standard breather caps via rugged steel pipe threads and a reusable metal base.

When the gold silica gel cartridge turns dark green, simply install a new replacement cartridge to keep things moving!
