share:

The STC/4 unit provides sterile air venting in both flow modes to atmospheric rated vessels. It is designed specifically for large vessels & tanks in the food, beverage, pharmaceutical, Oil and Gas industries. The STC/4 filter system is an easy to fit solution that can be terminated with any fitting or flange from 5″ upto 8″.

With an efficiency of 99.999%, the high flow rate of 1000m3/hr (277L/sec) at an initial pressure drop of 120Pa means the Foramaflow STC/4 is extremely efficient at a very low resistance. The filter system can be subjected to a range of harsh conditions. The maximum operating temperature of 120 Deg C and Hydrophobic Microglass water repellent paper to BS 2823 used allows the filter to operate during elevated temperatures, humidity, CIP procedures, vessel steaming and chemical attack. The provision of inner and outer grids ensures that filter integrity is maintained under reverse flow conditions during filling and emptying cycles.

The STC/4 HEPA Filter is manufactured under a patented process and has been engineered to provide absolute microbiological protection with an even higher flow rate against a low pressure drop.

The STC/4 Filter is certified in accordance with BS EN 1822 (H14) and tested against BS 3928.
