DN350mm Silicone Membrane Reinforced PP Support Part Disc Aerator
Diffuser
Product Description
350mm Disc Aerator Diffuser has 6 stiffeners plus circular stiffeners, the product is solid
and durable. The device has small aeration bubble, large gas-liquid
area, uniform bubble diffusion, no hole blockage and strong
corrosion resistance. When the aerator is aerated with oxygen,
several air supply tanks are designed on the main panel, so that
the incoming air can be buffered by the check valve and then
directly sent to the center of the aerator head to ensure that the
diaphragm can be opened easily at one time with low resistance.
The diaphragm is mechanically assembled with rib anti lock to
ensure that the diaphragm is not easy to fall off. During air
intake, the micropores on the air distribution membrane expand by
themselves to ensure air passing through. When the aeration is
stopped, the variable micropores on the gas distribution membrane
are closed. Because the variable micropores on the gas distribution
membrane expand and contract by themselves, the micropores passing
through the aerator are not blocked. Secondly, the bottom plate of
the aerator is provided with a check valve device to prevent the
mixed liquid from entering the gas distribution branch pipe when
the gas supply of the pipeline system is stopped, so as to prevent
the mixed liquid from entering the branch pipe and being blocked.
The air entering does not need special filtration, and the
intermittent aeration is not blocked. A great technical improvement
has been made to the phenomenon that the air distribution membrane
is easy to blow and tear, and the membrane cannot be opened or
blocked.
