They include 18’6” brush widths powered by 15 Liter 500 H.P. 6 cylinder diesel auxiliary engines providing over 5000 ft/lbs of torque to the broom at 540 RPM. They also incorporate high output high velocity dual airblast assemblies mounted mid-ship on the chassis. This powerful combination produces some of the strongest chassis mounted runway brooms ever produced. They were sold to Bangor International by HP Fairfield –
