Allied Witan – Porous Metal Breather – Vent Filter Spec

TOUGH, INEXPENSIVE AND LOW-PROFILE

A suitable alternative for spaces too small to accommodate standard Porous Metal Filter-Mufflers
Compact unit in standard porous bronze in 90 Micron is most often used as a breather-vent-filter for cylinders, gearboxes, crankcases, storage cases, storage tanks, and other vessels where pressure equalization is required
Modifications are available using Stainless Steel, Brass, other microns, or highly porous screen media to allow for unrestricted flow while limiting the infiltration of unwanted objects
Recommended for pressures up to 125 psi (8.6 Bar)
