Product Details

Active waste exhaust devices are adopted for urban rail transit vehicles with a speed of 120 km/h and below. Such devices function to give pressure protection instructions through the network system when vehicles pass through tunnel portals and section air shafts in the tunnel, and close fresh air valves and waste exhaust valves in advance, so as to inhibit external pressure fluctuation from being transmitted to the interior of passenger room.
