Fine Bubble Disc Diffuser:

Plate series aerators are composed of chassis, air distribution disc, synthetic rubber diaphragm, compression ring, air guide plate, connecting base and connecting pipe connection piece. The base is made of ABS plastic, and EPDM rubber diaphragm covers the air flow plate. Under the action of the fixed ring, no air leakage can be ensured around the diaphragm. A large number of evenly distributed holes are distributed on the rubber diaphragm. This kind of rubber diaphragm is made of multi-channel special processing technology, with stable performance and resistance to medium concentration of acid, alkali, oil and other media. It is an aerator put into engineering operation earlier.







Product features:

The flat type microporous aerator has a unique check function to effectively prevent pollution from entering the air distribution pipeline when it stop running.Easy to install, can be flexibly applied to a variety of processes in the sewage treatment system, is a mature and efficient aeration equipment.
