Auto Extract Systems Ltd’s sliding balancer tracks system incorporate a hose that moves within an steel extruded track.
The hose is directly coupled to the exhaust pipe on the emergency vehicle via a suitably sized hose and grabber nozzle. This nozzle is secured to the exhaust via compressed air fed from a compressor via the hose and nozzle assembly. As the emergency vehicle starts up exhaust emissions are detected by pressure sensors mounted within the rail, this in turn activates extraction fan to run via a control panel for as long as it can sense exhaust gas flow and for 30 seconds after it has finished sensing flow.When the vehicle then starts to drive off through the bay it eventually gets to a dedicated position at high level where a simple air release switch automatically deflates the grabber nozzle and releases the vehicle. These rails would be utilised in conjunction with one of our extraction fans to vent exhaust extraction fumes to atmosphere.
