I have a question regarding the one-way valve for the exhaust gas outlet pipe
Thread Content
To prevent backflow of exhaust gas when the exhaust gas discharge pipeline is connected to the main exhaust pipe, can a one-way valve for pipes be installed, or a regular one-way valve?
Regarding this issue, hehe~~~ If the air pressure is low, a fan with a check valve must be used； If the air pressure is high, a conventional check valve can be used ； It is recommended to use check valves for fans ；
