Giant Tank Breathers
These over-sized units stop airborne dirt from entering tanks as liquid is removed. They provide clean, filtered air fast to replace liquids going out at high rates - up to hundreds of gallons per minute
Giant tank breathers screw into NPT ports up to 3 inches in size. The threaded base is of nylon, which is strong, lightweight, and seals well against metal. (4-inch models with steel bases are also available.) The strong, steel cover protects the filter elements.
A wide selection of filter elements is offered. They are pleated to increase surface area and dirt holding capacity, and are supported by coarse wire mesh. Elements rated 40 micron and finer are made of synthetic or cellulose (paper) material. Those rated 74 and 149 microns are of stainless steel wire mesh. Elements are easily replaced and replacements are always available.
Select the style number and the element micron-rating you want and combine them.
Example: Style BF-2017 plus element 10C would be ordered as BF-2017-10C
BF-2018, 9, & 20
