Sterling SGM-250A User Manual

Note: Centrifugal 

separation 

systems 

must not be used for closed-

loop or chilled water systems; back flushing eliminates 
chemicals added to the system. 

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. 

 

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.
