This is adjustable and can be placed in the aspiration or exhaust channel. A filtering bag can be fitted at the end of the flow of pulsed, dust carrying air. A sound absorber fixed to or above the dividing knife can either be straight or half round. The channel roof can either be opened or removable for cleaning.</p> |
