The aeration work components are mainly composed of valves, ventilation pipes and diaphragm tube microporous aerators. Diaphragm tubular microporous aerators are made of rubber material with tiny self-closing holes on the membrane. When working, the micropores of the aeration tube will automatically open under air pressure, and the air will enter the pool for oxygenation, and if the pressure disappears, the micropores of the aeration tube will automatically close to prevent water from backing up into the micropores.
