Permanent Washable Water Filters

Keller provides a range of washable water filters as a solution to filter and clean even the dirtiest water. They are both cost effective and easy to use. The unique designs produced and supplied by Keller allows the filter components to be removed for cleaning, and then reused – significantly reducing operating costs associated with purchasing disposable water filter cartridges.

About Washable Water Filters

Keller offers superior water filtration with a wide range of permanent water filters. Our water filter systems can be used for a multitude of filtering requirements, from low level “coarse” filtering, to removal of visible solids down to 50 microns. Keller permanent water filter cartridges successfully filter both slimy solids and granular solids such sand. Our permanent, cleanable water filters provide exceptional water filtration with excellent additional benefits, including:

  • Washable water filter cartridges can be fitted to existing standard 5”, 10″, and 20″ filter housings without modification, or can be ordered as complete units from Keller’s full line of filter assemblies.
  • Water filter cartridges are simple to remove and quickly wash, to restore the filter element to new condition.
  • Permanent cartridges are an investment that end up “paying for themselves”, providing long term savings by eliminating the need for replacement filters.
  • Washable water filters save time as well as space, as no inventory of replacement cartridges is needed.  

Keller’s washable water filter system is a unique and cost-effective design, constructed of thin plastic discs that include precisely-sized grooves, and are stacked on a central core. The large internal filter surface provides long life between cleanings. When cleaning of water filter cartridges is required, this is a hassle free job that can be completed in a few minutes, with no specialized tools needed.  Keller also offers economical screen filters for less demanding applications.

Keller’s washable filters are ideal to filter dirty water from wells, ponds and municipal water systems to ensure a clean supply of water to:

  • Plant and laboratory water supplies
  • Cooling water systems
  • Boiler feed water systems
  • Water spray nozzles
  • Industrial water supplies

Filter Assemblies from 3/8″ to 2″ Lines Sizes Provide:

  • Filtration as fine as 300 mesh (50 micron)
  • Long life between washings because of the depth-filter characteristics of the unique stacked-disc design
  • Excellent performance with slimy solids and algae, as well as with granular solids
  • Flow rate to 150 gpm
  • Immediate shipment from stock

To Select the Filter Grade:

  • Use the 40 mesh or 80 mesh (200 micron) grade when heavy solids loading is expected, or when only relatively coarse filtration is required – for example, in cooling water loops
  • Use the 130 mesh (100 micron) grade to remove essentially all visible solids from the liquid – for example, for residential water supply and drinking water
  • Use the 300 mesh (50 micron) grade to protect finer disposable filters or carbon cartridges

Keller supplies filter systems for line sizes from 3/8″ to 2″, with flow capacities to 150 gallons per minute. To select the correct size Keller filter assembly, specify the filter assembly with port size equal to the size of the line on which it will be installed. The flow rate in the line will likely be less than the rated flow of the filter at 2 psi pressure drop (see chart below), and therefore the initial pressure drop will likely be less than 2 psi.
