A facility, which pressurizing the air in a smoke control zone in order to ensure the safety of evacuees from harmful smoke generated in the event of a fire, we called it a smoke control system. If air is supplied excessively, the door to the Pressurized Smoke Control Zone may not open because the door to the Pressurized Smoke Control Zone is higher than the external pressure. If the air is insufficiently supplied, smoke may flow into the Pressurized Smoke Control Zone when the door is opened. Therefore, technology to keep the pressure inside the Pressurized Smoke Control Zone at an appropriate level is the core of the smoke control system.

The Variable Air Volume System for Smoke Control is an innovative device that efficiently controls the amount of air supplied to maintain the pressure in the Pressurized Smoke Control Zone at the pressure level set by the user, by controlling the motor speed of the blower with an inverter.
