Auto Extract Systems Ltd’s magnetic sliding rails system incorporate a trolley that moves within an aluminium extruded rail.
The trolley is directly coupled to the exhaust pipe on the emergency vehicle via suitable sized hose and magnetic nozzle. This nozzle is secured to the exhaust via an bespoke series of permanent magnets. 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 this pulls at a certain break strength. The nozzle is released from the vehicle. These rails would be utilised in conjunction with one of our extraction fans to vent exhaust extraction fumes to atmosphere.
