MagnaRail designed for two or more emergency vehicles parked in tandem. A single vertical hose, an electromagnet and nozzle affix to the vehicle. Hose is connected to suction carriages running through the overhead exhaust rail. The nozzle slips off smoothly when the electromagnet is automatically switched off, as the vehicle passes through the door.

The auto-disconnect exhaust system is a 24-volt electromagnetic release type that captures 100% of the exhaust emissions directly from the tail pipe and discharges those emissions to a specific location by means of an exhaust fan. Upon emergency dispatch of the vehicle, the exhaust fan will automatically start prior to the engine being energized. The exhaust fan will remain in the “on” position for as long as any engine is running. Upon vehicle exit, the hose assembly remains connected
to the tail pipe and automatically disconnects at a specified distance outside the door by de-energizing the electromagnet. The nozzle and hose assembly will smoothly separate from the vehicle and safely retract to the stored position ready to connect to the vehicle upon reentry. Upon disconnection, the hose assembly is designed to stop the apparatus from swinging wide or coming in contact with the floor, avoiding the possiblity of endangering personnel or equipment. The hose will remain at the door, ready for reconnection. Once the apparatus has left the building, the fan will automatically shut down after a preset time interval. Upon return, the fan is automatically activated prior to vehicle entry and the nozzle is connected to the tail pipe in a standing position. Bending over to connect the exhaust system and expose the operator to harmful exhaust fumes is not an issue. There is no positive locking device or moving parts that will be connected to the tail pipe. After the vehicle has been turned off, the fan can continues to operate for a preset time interval, normally two minutes.
