Before this pressuriser system was installed, the evaporator coil would get wet, then dusty, and couldn’t be cleaned, filling up the cab with dust. The driver was actually struggling to even get a clear view out the front window!
Craig has blocked off all the original air inlets on the system, and fitted a pressuriser and filter system to pressurise the cab so it doesn’t fill up with dust and brings in filtered, clean air. A very neat result with a Highgate Air filter and pressuriser, tubing with stainless steel pipe and the heavy duty rubber 90 degree bends. This solution comes in 12V and 24V kits ready to go.
