Sterling SGM-250A 1-4BFS Series Bag Filters, 1-5SWF Series Full Flow Stainless Steel Filters

Note: Centrifugal separation systems must not be used for closed- loop or chilled water systems; back flushing eliminates chemicals added to the system.

1-4 BFS Series Bag Filters

BFS Series bag filters can be used for full flow or bypass applications. BFS Series filters feature single cell 25-micron polyester filter bags, and include pressure gauges. BFS bag filters are available for tower systems up to 150 tons and chiller systems up to 200 tons.

1-5 SWF Series Full Flow Stainless Steel Filters

SWF Series full flow stainless steel filters feature 304 stainless steel construction of filter housings, strainer baskets, and flanges. Maximum working pressure is 100 psi (689.5 kPa/6.9 bars); 150 psi (1,034.5 kPa/10.3 bars) is available. Maximum operating temperature is 110ºF (43ºC); consult the factory for higher operating temperatures. 80-mesh screen size is standard for the stainless steel strainer basket; 40 mesh can be used for cooling tower water applications. Options include ΔP pressure alarm and automatic purge valve with timer.

Note: Valving and bypass are not included with SWF Series filters.

BFS Series and SWF Series full flow filters must be installed with bypass piping so that plugging of the filter or temporary shutdown required for back-washing does not hinder process operation.
