The TJ-75 Hybrid Filter is one of the most innovative and advanced filters available for swimming pools.
The TJ-75 combines centrifugal cyclonic pre-filtration with tried-and-true cartridge filtration, creating an ultra compact and streamlined swimming pool filter system. The TJ75 installs directly on top of your pump, so you don't need any extra space on your equipment pad, and the 2 inch threaded couplings ensure free-flow operation on all pools.
How It Works: Using similar vortex technology found in modern cyclonic home vacuum cleaners, the centrifugal pre-filter removes most of the dirt from the water (up to 80%) before it even reaches the main cartridge filter. The pre-filter has sixteen independent centrifugal chambers that spin-away impurities from the water, working most effectively on dense debris (debris that sinks). Its clear chamber lets you see how effective it is, as the majority of sediment settles there, and it can be cleaned in moments just by briefly opening its purge valve. Then, the 75 sq. ft. cartridge filter captures the final micron-level impurities as the water returns to the pool. The pressure gauge indicates when the cartridge itself ultimately needs cleaning, which can be easily removed without tools and can be washed off with a garden hose.
In general terms, you’ll know it’s time to clean your filter when the Filter Pressure, as displayed on the pressure gauge, rises to the threshold recommended by the manufacturer - this is usually 7-10 lbs. above the “clean” pressure. Consequently, there are two key steps: 1) Confirm from your owner’s manual the pressure increase recommended for cleaning, and 2) Make note of your filter pressure when the filter is clean(ed) for reference purposes.
Estimates of filter cartridge lifespan vary widely from 1-2 years to 3-5 years and all points between. Where you might find yourself within those ranges can be influenced by your immediate environment, the square footage of filter media relative to pool size, and the extent to which your pool is subjected to body oils, lotions, hair products, etc. A great way to maximize filter cartridge life is to use a pre-filter which can intercept much of what otherwise reaches your filter cartridges.
The three main categories of pool filters are: DE Filters, Cartridge Filters, and Sand Filters which, respectively, can filter particles as small as 5, 10, and 20 microns. Cartridge Filters are removed from the filter and cleaned with running water and a cleaning solution, if necessary. DE and Sand Filters are subjected to “backwashing” pool water to clean debris from the filter media. This process can commonly take 2-300 gallons of water that will then need replaced, resalinated, and rebalanced. Cartridge Filters are the most water-efficient and are easiest to maintain, while DE filters give you the most effective filtration.
