DDI SuperFlex products

SuperFlex disc diffuser units are available with premium quality EPDM membranes. The diffusers incorporate an external triple-check valve design to prevent intrusion of liquid or solids into the diffuser or air piping under normal on/off operating conditions.

The DDI SuperFlex T-Series Aeration Tube Diffusers are engineered to enhance oxygen transfer efficiency and achieve optimum mixing performance in various applications. These diffusers utilize a fine pore, flexible membrane design, which is pivotal for optimal air dispersion in industrial and non-standard domestic settings. The standard unit incorporates a 3/4-inch stainless steel nipple, with optional configurations such as loose shipping or thru-mount connections for square tubing installations. The T-Series offers versatility with threaded units compatible with saddle mount styles, suitable for customized applications. Diffuser membranes typically include EPDM and PU materials, though alternatives like silicone and PTFE are available, along with polyurethane and specialty polymers for unique environments. Durability is ensured through 304 SS clamps, with 316 SS and nonmetallic options available. These units accommodate variable airflow rates, and a triple-check valve system is integrated to prevent liquid ingress and maintain system integrity under regular operational conditions.

The DDI SuperFlex Bubble Diffuser Mounts are engineered from glass-filled UV polypropylene, making them suitable for high-temperature and cold-weather applications in deep tanks. These mounts come in a range of sizes, accommodating 3-inch to 4-inch diameter pipes for the 9-inch unit and 3-inch for the 12-inch disc. The use of advanced membrane materials, including EPDM and specialized polymers, enhances performance and durability. The mounts feature a triple-check valve design that limits the intrusion of liquids and solids, minimizing maintenance needs. Additionally, the integral saddle mount simplifies both installation and maintenance processes. The high-capacity membrane option ensures optimal airflow and minimal operating pressure. A Universal Diffuser Mount (UDM) is available, designed for both fine and coarse bubble disc diffusers with specific NPT connections, adaptable to various PVC or metal pipe sizes. Special installation instructions cater to different piping materials and conditions.
