Extraction rail with pneumatic connection and automatic disconnection
A fast and easy-to-use solution for fire departments
Reliable Exhaust Nozzle Release—A Hallmark of NORFI’s System for Fire Stations
In emergencies, every second counts. That’s why we’ve developed an automatic nozzle disconnection system—designed for convenience, reliability, and efficiency. With NORFI, you no longer need to worry about manually disconnecting the exhaust extractor before departure.
How It Works:
1. The nozzle inlet is securely attached to the end of the exhaust pipe using air cushions mounted inside the nozzle.
2. The cushions are inflated manually by activating a valve, ensuring a firm grip on the exhaust pipe.
3. As the vehicle leaves the garage, it pulls the nozzle and the movable extraction trolley until it automatically disconnects.
Automatic Disconnection for Safety and Efficiency:
• Disconnection occurs precisely at a designated point to guarantee safety and smooth operation.
• The process is triggered by releasing air through a limit valve.
• The pneumatic clamping system requires a continuous supply of compressed air to function optimally.

Fan start settings in exhaust gas extraction systems for fire stations
The automatic fan start system uses an external control signal to initiate the fan start. This signal can be an alarm bell, an alarm light or an exit gate opening signal. Fan shutdown can be synchronized with the control signal fading or controlled by a time switch.
The radio fan start system initiates the fan simultaneously with the vehicle start engine. A radio transmitter installed in the car transmits a signal to the control box. The system is “tuned” so that a specific vehicle starts a particular fan.
The most straightforward fan-switching system is through a wall switch. The manual system can be equipped with a timer that will switch the fan off after a pre-set operating time. The manual switching system can also be installed at the control station so that the employee on duty can independently decide to switch the fan on and off.
