Description:
The Dura- Disc diffuser features several patented design elements which provide total flexibility in design, operation and installation. The fine bubble diffuser is built to provide the highest oxygen transfer performance obtainable over a wide range of air flows. The tapered, high quality EPDM membrane assures consistent air flow patterns important to optimum oxygen transfer efficiency. The unique mounting system allows great flexibility in the choice of pipe material and size and also provides automatic expansion capabilities. Also the Dura-Disc diffusers are designed to require minimal maintenance and the quality construction assures years of uniterrupted operation.
These diffusers feature permanently locked EPDM membranes for positive sealing and long life. Non-tearing I-shaped slits provide uniform bubble diameter and pattern. Glass-reinforced nylon base features a 3/4" NPT(M) connection and no metal attachment parts. The Posi Seal membrane is tested to 30 cfm and 8 psi.
