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

COAX™ Melt Blown filter cartridge

Two Stage Depth filter cartridge

The COAX Depth Filter cartridge is an integral two stage depth filter. The first stage of the filter cartridge is made of non-woven melt blown polypropylene to trap coarser articles.

The second stage inner core is composed of a bi-component polypropylene and polyethylene fibre to provide fine particle retention. This unique design provides a true graded density filter cartridge that offers a marked increase in useful life and dirt capacity.

In addition, the rigid nature means there is no flexing of the cartridge and greatly reducing media migration and particle unloading.

High Flow Series Filter Cartridges

Large Geometry Pleated Filters for High Flow

Graver High Flow Series filters feature a larger geometry to handle higher flows with fewer filter elements. The result is much faster, easier filter changeouts. In addition, the inside to outside flow allows for excellent dirt holding capacity, extending the time between filter changeouts.

Filter housings are also available and because of the filters high flow and dirt holding capacity, smaller systems are possible, reducing upfront capital costs.

High Flow Series Features – Benefits

  • 6” diameter, large geometry for high flows
  • Absolute retention ratings from 1 to 100 microns
  • Capable of flow rates up to 500 GPM in a single 60” element
  • FDA listed materials of construction
  • Inside-out flow retains contaminant even during change-out
