SSI AFD Disc Diffuser System combines engineering excellence, superior component quality, and a technically advanced product design, Proven highly durable and efficient in thousands of municipal and industrial installations around the world, this advanced system has reliability built into every stage of performance. SSI's AFD comes in several membrane materials including our patented PTFE membrane, designed to use less energy and require minimal maintenance. Industry stand and size and shape are inter changable with other manufacturers. The diffuser base is molded with virgin polypropeline for extended performance, and is highly efficient with airflow performance of 1.5-2.5 SCFM.

Single mold tichnology to reduce costs.

Availabe in 4 versions:7",9",12" and 20".

3/4" M NPT connection.

High efficiencies(SOTE) and lowpressure dropstested according to ASCE standards.

High resistance environmentally friendly polypropylend body(100℃).

Membrane with low plasticzer content to minimize the phenomena of loss of elasticity and shrinkage
