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.
The diffuser's streamlined wedge shape improves stability in tanks with high water flow and offers less resistance in self-cleaning tank systems.
Single base (unassembled) diffusers measure 5.4" x 6.6" x 1.25". Recommended flow 1.6 cfh (.75 Lpm). Recommended operating pressure is 22–35 psi, maximum pressure is 50 psi*. Inlet is 1/4" barb fitting (only included with end set). One-year warranty.
Features and Benefits
• Flexible, modular design lets you easily add or subtract diffusers to match your changing needs.
• Simple "twist and lock" installation—diffuser modules and hose connect in minutes without the use of tools.
• Rugged thermoplastic build is corrosion-free and UV-resistant.
• Streamlined wedge shape improves stability in tanks with high water velocity.
*Above 50 psi (3.4 bars) the diffuser can break.
