Balanced air pressure
In ZUM, fans are used for both air intaking and outtaking to keep the air pressure from the outside.
Centrifugal fan
The fan noise becomes apparent when it is quiet in the booth. We use centrifugal fans for air intake to achieve smoother airflow at lower speeds, creating less noise.
Automatic refresh
Every 30 minutes, the fan will start to ventilate the air automatically for 5 minutes, which keeps the duct and booth dry, smelling fresh, and ready for the following user.
