Pool Filters Types

      The pool filter is an indispensable part of your pool.  That is the part that traps all dust particles, small debris, and of course the bacteria and algae previously killed by the sanitizer in the water and keeps it there until it gets permanently discarded through a backwash or cartridge wash. No matter how much chemicals you pour into the pool without a properly functioning filter the water will never look good and your pool will lose its appeal.
There are three main types of filters they all differ by size, ease of maintenance and operation and quality of filtration.

Sand Filters

Diatomaceous Earth is a porous powder with microscopic openings, that, when magnified, look like tiny sponges. Clearwater can pass through these openings, but particles, as small as one to three microns, are trapped during the first pass through the media D.E. filter have internal elements that become coated with D.E. is this "filter Cake" that strains dirt, dust, algae and some form of bacteria from the water.

1. Automatic Air Relief purge any trapped air during filter operation.

2. Integral Lift Handles and Uniform Low Tank Base make removal of grid nest fast and simple.

3.High-Strength Filter Tank molded of PermaGlass XL provides extra durability for dependable, corrosion-free performance.

4.  High Impact Grid Elements designed for up-flow filtration and top-down backwashing for maximum efficiency.

5. Heavy-Duty Tamper-Proof Bolted Center Flange Clamp securely fastens tank top and bottom together. Allows quick access to all internal components without disturbing piping or connections.

6. Union Locknuts make disassembly and reassembly of the filter from piping fast and easy.

7. Norly Bulkhead Fittings for extra strength and heat resistance.

8. Inlet- Diffuser Elbow distributes the flow of incoming unfiltered water upward and evenly to all filter elements. Parabolic tank design provides for even distribution of D.E. to the grid.

9. Full-Size 1.5" Integral Drain provide fast 100% clean out and easier flushing of the tank.

10. Convenient Valve and Plumbing Options allow for customized control. 2" internal piping and plumbing for maximum flow performance.

Similar to sand filters, when D.E. filters become dirty, they are cleaned either by backwashing or regenerating and draining the clogged D.E. to the 'waste' line. To restore filtration, a fresh 'charge' of D.E. is added to the filter.

Cartridge Filters
