General Information
What You Should Know About Filler Breathers!

Sizing is based on the reservoir air exchange requirements, NOT the pump output.  Magnaloy Filler Breather Assemblies are sized for a maximum pressure drop of .45 in. Hg.

Hydraulic users rarely change the breather filter, which can contribute to pump cavitation.  A routine of regularly changing or cleaning the air filter should be developed.  A vacuum indicator can be very helpful.

 

The NFPA standard calls for TWO filler openings, each of which should pass a minimum of 5 GPM.  They should be located on opposite sides or ends of the reservoir.

The maximum air filtration allowed is 40 micron.  All of Magnaloy's Filler Breather Cap are 10 micron.

The filler screen should be at least 30 mesh and should have an internal metal guard to prevent the spill spout from puncturing the screen.  All Magnaloy's screens are 30 mesh and we offer a screen guard as an option.
