With a 647 CFM airflow capacity, a totally enclosed fan cooled permanently lubricated 110 volt motor, and a 9-inch precision spin-balanced impeller, the 10-005 M1 is designed for continuous duty applications. The collector body is supported on 3 heavy-duty rods and mounted to a sturdy steel base with 4 swivel casters allowing complete mobility within the shop. Equipped with an ultra-fine 2 micron washable filter bag and a 20 gallon collector bag with see-through window to monitor dust accumulation, the 10-005 M1 is ideal for collecting fine general purpose wood dust and composite dust in shops where the unit must be mobile and positioned at the dust source. The front mount 4-inch hose inlet is equipped with an intake screen to prevent larger pieces from jamming in the impeller. The sound rating during operation is 75-80 decibels and its overall dimensions are 30-3/4 by 17 by 54-1/4 inches. Note: the 10-005 M1 is not recommended for use with planers or jointers. For effective results with planers and jointers consider instead 1000+ CFM models such as the 10-105 M1.
