Easy installation and even gas distribution. The super elasticity of the TPU material makes the aeration aperture variable with the size of the air supply; With the excellent strength of TPU material, the thickness of pipe wall can be made to 25% of that of rubber and PVC aerator, which can greatly reduce the aeration resistance loss and achieve the purpose of energy saving; Long-term operation, low operation cost; TPU material, better performance than other types of aerators, stable operation, longer service life; Excellent high pressure resistance, oil resistance, weather resistance, corrosion resistance, and quorao resistance, light weight, soft and convenient to use, special ultra-micro hole way to increase the oxygen utilization rate to more than 30%. Due to the characteristics of bending resistance, the package volume is small and the transportation is more convenient.
