Easy access clamp assembly
Cleans pools fast -- removes even the smallest particles the first time through
Uses D.E. (diatomaceous earth) filter powder -- the most efficient dirt remover known for swimming pool filtration
Patented Flex-Tube™ system efficiently reuses D.E. powder and dirt mixture to form fresh cleaning surfaces
Exclusive bump handle activates the Flex-Tubes, causing them to instantly purge themselves of dirt and powder
Uniquely designed to expel any air that may be present in the system through the filtered water returning to the pool
Combination diffuser and lower mixing chamber specifically designed to produce a uniformed coating of D.E. on the Flex-Tubes
D.E. Required: 4lbs
The EC40AC is most efficient on Above ground pools 12x24 to 18x33 oval, 10' to 28' round, or 2,000 to 18,000 gallons.
The Perflex EC-40AC uses diatomaceous earth filter powder which will remove particles as small as two to five microns, including dust and pollen.
Unfiltered water enters through the bottom connection in the filter tank, flows upward through the Flex-Tubes and returns to the pool via the outlet in the filter head.
When the filter is initially started, diatomite filter powder is fed into the system.
As water passes through the Flex-tubes, the filter powder is automatically deposited on the outside of the Flex-tubes, forming the working "filter surface."
Eventually, the accumulated dirt causes the filter pressure to rise and flow to diminish.
Simply activate the Perflex "Bump" handle and within a minute, flow and pressure are back to normal.
Diatomaceous earth is a porous powder with microscopic openings that when magnified look like tiny sponges. Clear water can pass through these openings, but particles, as small as two to five microns, are trapped during the first pass through the media. D.E. filters have internal elements that become coated with D.E. It is this 'filter cake' that strains dirt, dust and algae from the water.
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 through the skimmer while your pump is running. For sparkling, clean pools; step up to Hayward D.E. filters.
