Flowrite Tank Breather Filter

Flowrite “TB” Series

Flowrite “TB” Series Tank breather filters are fabricated from 304-Stainless Steel. They are designed for a maximum operating pressure of 100 kPa at80ºC, depending on cartridges fitted. The “TB” Series housings feature Flowrite’s well proven centre post and nut design. Cartridges are located by their own end seals and a securing plate to which is attached a perforated stainless steel shield which allows free passage for the entering and exiting air during tank emptying and filling cycles.

The cartridges have double ”O” rings which give a perfect seal between cartridges and housing, thus eliminating any possibility of bypass. The practical and sturdy design of these housings allows quick and convenient cartridge change out of the 9¾” modular length filter cartridges.

Flowrite “TB” Series filter housings are available in one, two, three & four cartridge configurations to minimize pressure drop, and thus protect the tank from differential pressures while emptying or filling. The inlet port can be threaded or flanged to your specifications, and the unit is supplied in electro polished finish suitable for most semi and non-sanitary applications.

The housing should be used in conjunction with hydrophobic cartridges with a micron rating to your specification, which are also available from Flowrite
