8 Inch Silicone Membrane Fine Bubble Disc Diffuser Aerator In Blue
Product Description
Crown type aerator and support tray have unique spherical cap
structure. Structure and working principle: the spherical crown
microporous aerator is mainly composed of aeration diaphragm,
support tray, screw gland, threaded nozzle and other components. As
long as the rubber diaphragm is sheathed on the support tray, screw
gland can be used for tightening.

Product Features
1. The overall structure of the aerator is scientific and
reasonable, with advanced technology and novel design.
2. The aerator has excellent performance of anti blocking and
water-proof body backflow. Under the intermittent operation
condition, it is not easy to deposit sludge on the surface of the
aeration membrane, which has longer service life and higher oxygen
charging efficiency than the flat membrane microporous device, and
is also suitable for biological treatment of micro pollution of
source water. Features anti blocking and anti backflow.
3. The aerator is in the shape of a spherical crown. Even though
the water quality of the aerator is complex, it still operates
intermittently, and its surface is not easy to deposit mud. The
drilling technology of the diaphragm is unique and advanced, which
is inclined through the incision. In addition, a special seal ring
is set in the center of the top to effectively prevent the backflow
of water.
4. The diaphragm has strong tear resistance. The rubber diaphragm
is of spherical crown shape. When it works, the opening force of
the eyelet is uniform, the fatigue deformation degree is reduced,
the resilience is good, it is not easy to tear, and the service
life is long. Uniform air distribution, energy saving and high
efficiency. The working surface area of the spherical crown aerator
is relatively larger than that of the flat plate, with small
bubbles, uniform air distribution, high oxygen charging efficiency
and good treatment effect. Especially in the low gas work, it can
still play this feature, convenient operation and management.
Resistant to aging and corrosion.
5. The spherical cap aeration diaphragm is made of high-quality
rubber, and the supporting tray and threaded nozzle are all
engineering plastics. These materials have excellent physical and
mechanical properties. It has excellent aging resistance, acid,
alkali and chemical corrosion resistance. The resistance loss is
small.
6. Due to the unique anti blocking and waterproof backflow
performance of the aerator, the check valve attached to the flat
microporous aeration is omitted, thus reducing the resistance of
the aerator. Energy saving.
