Donaldson Breathers

Breathers filter the air a reservoir or tank draws in. As fluid level rises and falls, or as the tank heats and cools, air moves in and out through the breather - and whatever that air carries goes with it. An open or failed breather is one of the most common routes for dust and moisture to enter an otherwise clean hydraulic system, which then puts the load back onto the system filters.

The range covers simple filler breathers, spin-on breathers and desiccant types that also remove moisture from incoming air. Selection depends on the reservoir fitting, the air flow the system needs and how humid or dusty the environment is. Search by Donaldson part number, or enter the number from the existing breather to match it against the cross-references we hold.
