- The closed-loop REGENERATIVE AIR SYSTEM uses the force of a high velocity controlled jet of air created by the powerful blower wheel.
- This jet of air blasts down and across the pick-up head onto the pavement and into the cracks forcing up into the air stream packed-on heavy debris as well as fine dust particles.
- The debris-ladened air stream is pulled into the large hopper, where the air loses velocity and the larger debris falls to the bottom. A screen at the top of the hopper prevents items such as leaves, paper, cans and rocks from leaving the hopper and entering the centrifugal dust separator.
- The patented centrifugal dust separator spins the air along the curved wall of the chamber until the micron-size dust particles are skimmed off into the hopper. Only clean air is returned to the blower to start the Regenerative Air cycle again. This closed-loop system means no dirty air is exhausted into the environment only to settle on the surface again.
