A device used as a combined scrubber and water droplet eliminator which may be employed in removing particulate from air, especially in conjunction with an underground mining machine. The scrubber is made of a fibrous bed material and is rotatable by a motor forming part of a bed assembly. Adjacent to the rotatable bed are water sprays directed to spray towards and on the bed as it rotates. A suitable air movement device, such as a fan, draws dust-laden and water drop-laden air to the rotating bed. The air goes through the bed and the dust and water particles impact the bed's rotating wetted fibers and are forced radially directly outward. The bed's rotation takes place against the inlet portion of a stationary bell mouth assembly. An air seal caused by the air pressure differential seals the rotating bed to the inside surface of the assembly. The rotating bed causes particles and water to be moved towards the bed's circumference where an open weave allows the particles and water to be dispersed in a continuous flushing action.
