Sterling FILTRATION AND SEPARATION SYSTEMS SGM-250A - Manual (Page 7)

Water Management Systems and Products Page 7
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.
