The CFM 3508 is a powerful 4kW three phase industrial vacuum cleaner, giving a higher vacuum than the CFM 3308 enabling faster removal of heavier rubble, solid materials and with the correct adapter kit, liquids. This model is ideal for use in a constant production system, which would be too demanding of traditional single phase motors with carbon brushes and armatures that wear. The Absolute filter, upstream safety filter, a manual filter-shaker, an accessories compartment and easy access to the motor compartment, are features of this model. * 3 Phase 4.3kW 415V induction motor * Sound level 72 dB(A) at one meter * Vacuum/Depression 4,600kPa * Airflow 85lit/sec * Main filter area 19,500cm² * Dust container capacity 100 litres * 70mm Inlet * Dimensions 157cm High x 65cm Wide x 125cm Long * Mass 210 Kg
