Aeration diaphragmIt is made of composite, EPDM rubber and silicone rubber , which has heat resistance, acid and alkali resistance, good chemical stability, and has a longer service life than general rubber. The air pipe is made of engineering plastic ABS , which is hollow and filled with water, which greatly reduces the buoyancy of the aeration system in the water. The support tube is made of ABS or PVC . The tubular aerator is composed of three parts: aeration diaphragm, air pipe and support pipe.
