Pentair Aquatic Eco-Systems Point Four™ WEDGE-LOCK™ Diffusers
WEDGE-LOCK™ is a modular system of diffusers and end sets that fit together to form a bank of up to eight units. Oxygenation capacity can be increased (or decreased) as your needs demand by simply changing the number of diffusers used for greater flexibility and minimal downtime.
Designed for total ease of use, WEDGE-LOCK™ modules "twist and lock" together to form an airtight seal without the use of tools. Hose with push-in fittings connects the diffuser banks to the gas supply, significantly reducing set-up time and effort.
Manufactured from tough plastic, WEDGE-LOCK™ will not corrode and is resistant to the sun's ultraviolet rays. The diffuser's streamlined wedge shape improves stability in tanks with high water flow and offers less resistance in self-cleaning tank systems.
The streamlined wedge shape is more stable in tanks with high water flow. Single base (unassembled) diffusers measure 5.4" x 6.6" x 1.25" and weigh 1.8 lbs. Recommended flow 1.6 cfh (.75 Lpm), maximum flow 3.4 cfh (1.6 Lpm). Recommended operating pressure is 22–35 psi, maximum pressure is 50 psi*. UV-resistant plastic. Inlet is 1/4" barb fitting. One-year warranty.
