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.
