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.
