1. The rubber diaphragm adopts EPDM rubber, which has the characteristics of heat resistance, ozone resistance, acid and alkali resistance, and good chemical stability. Compared with the general rubber membrane, it can greatly improve its service life.

2. The aeration hole is a long straight hole, so that it has good stretchability and instantaneous closure to obtain a higher oxygen utilization rate

3. The support tube is made of ABS or PVC.

4. The air pipe is made of engineering plastic ABS material, which is hollow and filled with water, which greatly reduces the buoyancy of the aeration system in the water. It has good chemical stability, does not contain plasticizers, can maintain elasticity for a long time, is resistant to acids and alkalis, does not harden, does not embrittle, and does not age. The bubble diameter of the product is small, which can not only maintain a high oxygen conversion rate, but also achieve the effect of mixing and stirring. The self-closed cell structure is adopted, and the micropores are not blocked. Easy to install and disassemble. Reduce energy consumption.
