Features
♦ Good effect on saving in power, and low operating cost
Because of the high oxygen transmission efficiency, a low powered blower can satisfy the oxygen volume required by the aeration process. As a result, power is saved, operating cost is decreased, and the cost is reduced.
♦ Excellent counterflow prevention function
The backstops are all equipped with valves to avoid counterflow when the air transmission is broken off, enabling the pores to shut smoothly and applicable to intermittent operation. It's unique and even air vents can lead the airflow effectively and can prevent sewage water from flowing into the aerator pipeline effectively.
♦ Long guaranteed life
The EPDM membrane is a special elastomeric polymer with high non-deformability and anti-tearing index. The membrane is made at even thickness with small pressure. Special processing technology is used to overspread 6000 micro-pores on the surface of the membrane. Under running condition the air bubbles rise with spiral whirlpool, giving self-purification ability to the membrane. The life of the membrane under normal use is guaranteed for 5 years, but usually, it is necessary to use it together with the water removal system.
♦ Unique ring seal
The aeration head tightening ring provides a tight-sealing effect between the aeration head base and the membrane washer -- the higher the air pressure, the better the sealing effect.
♦ Easy installation
PVC soft connector can be installed directly without any other auxiliary tools. The operation is easy and convenient.
