Filtration Systems

Models FBS and FBF

  • Steam and Hot Water Applications
  • Sized from 50,000 to 100,000 grains capacity
  • Flow rates from 2 to 800 gpm
  • Tank sizes range from 9" to 72"
  • Compatible with all boiler applications

Filtration systems remove impurities.

Raw water analysis can easily determine the need for special filter equipment for removal of impurities.  The cost of these systems is quickly recovered by eliminating the need for frequent equipment cleaning and servicing, inefficient performance, damage to system components and premature equipment failure. 

FBS water filters feature carbon steel media tanks with NSF 61 epoxy tank lining. The exterior piping is steel with cast-iron fittings and control valves. It offers the same filtration capabilities as the FBF Series. 


  • Flow rates from 10 to 800 gpm
  • Pipe sizes available from 1" to 8"
  • NEMA 4X electrical enclosure
  • Optional ASME code-stamped tanks
  • Optional skid mounting, pre-piped, pre-wired systems
  • Optional PVC, CPVC, copper or stainless steel exterior face piping

The FBF Series provides the latest technology in fiberglass tanks with top-mounted control valves. Only the filter media needs to be changed to successfully treat a variety of water problems. Cleaver-Brooks Series FBF water filters can treat for sediment removal, iron, manganese, hydrogen sulfide removal, acid neutralization, and chlorine removal. 


  • Flow rates from 2 to 96 gpm
  • Pipe sizes available from 1", 1-1/2", 2" and 3"
  • Seamless non-metallic fiberglass tanks for maximum corrosion resistance
  • Top-mounted, fully adjustable, brass control valves
  • One-third the shipping weight of steel tanks
  • Single-, twin- and triplex systems available

Case Study

Properly Treat Boiler Water for Efficient Long-Term Operation

To ensure a boiler runs properly over the course of its lifetime, treating the water that circulates within the system is mandatory. If the water is not treated properly, the boiler will begin to have problems within the first year, and its useful life will be significantly shortened. Boiler symptoms resulting from untreated water include overheating, failure to produce hot water or steam, a drop in the boiler flow rate and an overall loss of efficiency.
