Domestically pioneered tubular rubber aerator. This product is a new type of tubular rubber aerator developed by our company. It utilizes a main air supply pipe and a pilot air groove to perform microporous aeration through the expandable pores of the rubber membrane. It features a simple structure, high oxygen utilization rate, reliable performance, non-clogging pores, no backflow of sewage, uniform circumferential stress, long service life, easy installation and maintenance, and low system cost. This product is a domestic innovation and reaches the level of international counterparts. It is currently one of the most economical and reasonable aerators available.

II. Product Structure
　 ● Tubular structure reduces the tension on the membrane compared to disc aerators;
　 ● Pilot air groove design eliminates buoyancy in the aeration components;
　 ● The rubber membrane uses natural rubber and an anti-aging formula, ensuring a long service life;
　 ● Uniform and numerous pores, with up to 6624×2 pores per group (ordinary aerator membrane Φ215 has 2000 pores);
　 ● Stainless steel connecting fasteners prevent air leakage at joints and allow easy disassembly.

III. Features
　 ● High oxygen utilization rate, uniform air distribution, and no clogging;
　 ● Long service life, no water accumulation in the air pipes, stable and reliable performance;
　 ● Simple installation structure, no buoyancy in the aeration tubes, and user-friendly design.
