In the case of very high dust volumes, as is the case when working with surface-restoration millers and diamond grinders, for example, the CTM 36 AC HD is in its element. The AUTOCLEAN (AC) automatic main filter cleaning regularly rinses the high-performance main filter clean and guarantees a constantly high suction power. The extremely robust design with large wheels, steel axis and pivoting castor wheels provides stability on any surface – together with a high degree of mobility. The large container geometry of the CTM 36 AC HD offers a large 36 l container volume. The flat filter fully integrated in the suction head ensures the full volume is utilised: This means that the gross and net container volumes are virtually identical. The extremely compact high-performance turbine provides the right suction power. A 3900 l/min volume flow means that nothing remains except clean air. Approved for dusts in dust class M.
