New Filter Element Design Gives You These Benefits:
- A quick wash restores the filter element to new condition
- Permanent elements quickly pay for themselves through savings
in replacement cartridge costs
- No inventory of replacement cartridges needed
- Eliminate the problem and expense of disposing of contaminated
filter cartridges
- Fit the permanent elements in your existing standard 10"
& 20" filter housings without modification, or order
from Keller's complete line of filter assemblies
Filter Water from Wells, Ponds, and Municipal Water Systems to Protect:
- Plant and laboratory water supplies
- Cooling water systems
- Boiler feedwater systems
- Water spray nozzles
- Drinking water and eye wash water supplies - All components
comply with FDA regulations
- Residential 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

The novel filter elements are constructed of thin plastic discs
with precisely-sized grooves, stacked on a central core. The large
internal filter surface provides long life between cleanings.
When cleaning is required, it is a simple job of a few minutes
- no tools needed.
The permanent filter elements fit in standard 10" cartridge
filter housing without modifications.

Keller supplies filter assemblies containing the permanent, washable
filter elements in line sizes from 3/8-inches to 2 inches (150
gallons per minute)
