High Oxygen Transfer Disc Diffuser |
|
 |
Main functions & structure: |
Made up of low resistance materials, the device has a membrane surface composed of high polymer, hydrophobic long fibers. The specially gloss-treated surface is designed with more than 6000/㎝² pores to generate radiating fine air bubbles with less than 200mmAq (Aqua) wind pressure.
The check valve located at the diffuse membrane and the air opening is installed with a corresponding inverted cone, an upward diffuse membrane, and a downward sealed air valve.
The high polymer long fibers, combining with tensile resistance strength of more than 10kg/25mm, and an elongation rate of less than 20%, make our diffuser more suitable for aeration function in deeper water.

Features: |
High strength, high thermal resistance of up to 150°C, good functionality (long durability under environment of 90°C), aging resistant, anti-ultraviolet rays, high stability and light-weight, super ventilation, anti-erosion, anti-acid, strong basicity, and low wind pressure loss. |
High oxygen transfer efficiency: |
When air passing through more than 6000/㎝² pores distributed evenly across the membrane of the disc diffuser, it continuously generates fine bubbles with a grain diameter of 0.5 ~ 3mm, which can increase air-water contact area to a great extent. SAME Disc Diffuser has been scientifically proven to have an oxygen transfer rate of over 26% by the Energy and Environment Research Laboratories of Industrial Technology Research Institute. |
