Wedge-LockTM is a modular system of diffusers and end sets that fit together to form a bank of up to 8 units. Capacity can be increased or decreased as your needs demand by simply changing the number of diffusers used for greater flexibility and minimal downtime. The cases are made of rugged thermoplastic and the streamlined wedge shape improves stability in tanks with water flow. 
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.

WEDGE-LOCK™ uses an ultra fine pore ceramic producing a high Absorption Efficiency (AE) allowing you to increase yield while controlling the cost of expensive gases.
