This is an air valve that protects stable water flow in pipes with high quality born from the pursuit of functionality and rationality!

"Aeris Neo" is a non-freezing type that utilizes the flowing water energy of the main pipe, and it is an air valve that maintains a stable water flow within the piping. We have now published a video for maintenance! It adopts the "rotating slide method," which is a major feature of Aeris Neo. This method does not require special tools, making maintenance easier and allowing for safe work by simultaneously sealing the side and bottom holes. We have created a "Maintenance Guide" detailing maintenance precautions and procedures! For more information, please download the materials or feel free to contact us if you have any questions. [Aeris Neo Features] ■ Easy maintenance with the rotating slide method that does not require special tools ■ Optional parts are also available separately ■ Special structure with a sub-valve function and non-freezing design *For more details, please refer to the catalog or feel free to contact us.
