Auto Extract Systems Ltd’s vertical sliding rails system are designed for upward facing exhaust stacks on emergency vehicles.
A flexible rail is installed at a fixed height just above the bay area. Guide springs allow the track to move left and right up to 600mm and this operation collects the moving vehicle as it approaches the canopy and guides itself into the rail assembly. The exhaust emissions are detected automatically within the rail by small 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. Benefits of this system include that no person has to touch the vehicle either on entry or exit. These rails would be utilised in conjunction with one of our extraction fans to vent exhaust extraction fumes to atmosphere.
