About Airfin ®

Airfin ® diffuser consists of porous membrane made of EPDM or SILICON rubber. Each diffuser is fully –supported over the length and circumference with a PVC pipe. The diffuser is retained in place by two hose clamps. It is fitted to the lateral by a PVC heavy duty ‘T’ arrangement or SS-304- 3/4”BSP nipple. The Laterals are connected to a pipe header. For floating type laterals, the diffuser unit is fitted on concrete block with PP rope arrangement hence easy to maintain. The wetted parts of system are made of non-corrosive material. In the absence of air, the membrane contracts and covered around the support pipe to prevent any Backflow.

Advanced Designed Diffuser from EPDM, Silicone, Styrene butadiene rubber or specially engineered materials are available. Highly engineered pores on membrane for maximum efficiency with back flow prevention.

The properties of material are tested by CIPET – a reputed testing laboratory.
