8 Inch Crown Type Fine Bubble Disc Diffuser Aerator with ABS Support Part
Product Description
The disc diffuser aerator is a kind of aerator developed in 1980s. It has the advantages of small aeration bubble, large gas-liquid area, uniform bubble diffusion, no hole blockage and corrosion resistance. ABS engineering plastic is used as the main body, and EPDM rubber is used as the diaphragm. The diaphragm opening is made by machining. The numerical control opening is used to ensure the quality and accuracy of the hole. When the aerator is aerated with oxygen, four air supply tanks are designed on the main panel, so that the incoming air can be buffered by the check valve and directly sent to the center of the aerator head, so as 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 keep the diaphragm from falling off. When air enters, the micropores on the air distribution membrane expand by themselves to make air pass through.

Product Features
1. EPDM Rubber diaphragm
Select imported high-quality rubber raw materials, according to the requirements of aeration conditions, customize the material composition and proportion, excellent physical and chemical properties, effectively prevent the diaphragm from shrinking, hardening and aging, and extend the product life.
2. ABS Plastic support plate
Polypropylene and glass fiber are used, and anti aging additives are also provided. The product has excellent toughness while retaining enough strength. The product is resistant to oxidation, UV, impact, creep and corrosion, with stable and stable performance, strong and durable.
3. Process technology, professional and reliable
(1) Professional membrane surface treatment technology, special drilling technology, to ensure smooth surface, small pores, products are not easy to scale, small bubbles, uniform air distribution, effectively reduce the shear damage of bubbles to activated sludge particles, and improve the biochemical activity of the system.
(2) The rubber diaphragm production adopts the molding process to ensure the uniform specific gravity of the diaphragm, multi-directional tear resistance and high tear strength.
(3) Mechanical assembly production line, with hot-melt welding instead of adhesive process, to ensure adequate supply, product quality uniformity, stability and reliability, highly repeatable.
(4) Dust free production workshop, to ensure that the goods are free of impurities, to ensure that the product is stable and reliable.
