HDH-series microporpous diaphragm aerator could be applied to the aeration work of all kinds of sewage treatment.

1. made of imported EPDM, which is anti-aging, anti- corrosion and hasdurable service life 

2. Stair-stepping seal structure can prevent the diaphragm loosing off 

3. periphery of diaphragm is thickened to compensate the extension, the thickened part can protect the rubber diaphragm from tearing up by concentrated stress

4. double reflux valve design  can prevent sewage seeping into the pipeline system 

5. special once molding process forms fine micro pores on the diaphragm, makes the air bubbles diffusing evenly less resistance loss

6. diffusing air bubbles are fine and even, enhances the oxygen utilization and oxygenation  capacity

7. good self-cleaning and anti- clogging property

8. standard 3/4 inch screwed joint, 

9. can resist high temperature up 100°c and could work well deep pool aeration
