2.The diaphragm is made of high quality rubber raw material and installed on the chassis bracket.

Technical parameters

Working principle of Fine Bubble Diffuser

The chassis support is the support of the diaphragm, which is arched. The upper part of the chassis support is provided with eight air diversion grooves which are distributed around the center to ensure that the air is evenly distributed. The spiral cap joins the lower part of the chassis support to the chassis support. The diaphragm is fixed on the chassis support. The chassis support and the spiral cap are molded by quality ABS engineering plastics.
