Steel Tank-Vent Filter Holders

I am interested in Steel Tank-Vent Filter Holders Please call me back

Tank-Vent Filter housings are used for breather filters. Breather filters are designed to prevent penetration of environmental microbiology into the vessel when it is discharged and to prevent contamination of the vessel content during storage. In addition, breather filters protect fermenting and beer storage tanks against vacuuming. Tank-Vent Filter holders are designed to incorporate filter cartridges of 65 mm, 125 mm and 250 mm height.

Breather filters are available in three modifications: DS-FD-65, DS-FD-125, DS-FD-250.

Materials of tank-vent filter holders

AISI 304 (12X18H10T) stainless steel

Configuration and operation principle

Breather filter consists of a base, cover, hydrophobic fluoroplastic (EPM.F4) membrane filter cartridge and a collar for welding. When discharging the vessel, the air incoming from the atmosphere passes through the element where it is purified and 

gets into the vessel. When the vessel is filled, vapors pass through the element and are discharged into the atmosphere.

Preparation for operation

After the collar is welded, the vessel is disinfected, then the base, filter and protecting cover (cap) are installed. The base and the cover, the collar and the base are connected to each other using clamps (TRI-CLAMP quick release couplings).
