The Schwarze A4000 Street Sweeper is a chassis-mounted, regenerative air sweeper with a 4.3 cubic yard capacity. The basic design of the A4000 street sweeper has had many years of successful operation throughout the United States and around the world. Because of its relatively compact size, the Schwarze A4000 street sweeper requires no Commercial Driver's License for operation and offers great maneuverability. With its sweeping power and environmentally-friendly regenerative air design, the A4000 is an ideal choice for use in a wide range of demanding road sweeping applications.

The A4000 sweeper's blower system generates a high velocity air column which is propelled into the top of its sweeping head through a 12-inch blast tube. The air is first pressurized in the upper chamber of the sweeping head, then expelled into the head's lower chamber through what is called a "blast orifice". This is a slot in the sweeping head that forces the air against the pavement at an angle, creating a "peeling" or "knifing" effect. The high volume air blast loosens the debris from the pavement surface, then transports it across the width of the sweeping head and lifts it into the containment hopper via a 12-inch suction tube. The blast and suction on the A4000 sweeper is generated by the Schwarze-exclusive WhisperWheel^sm fan system.

This is a highly efficient system which ensures that even hard-to-reach particles hidden within pavement cracks and irregularities are removed, including the "PM-10 fines" known to contain a high percentage of heavy metals, phosphates and other pollutants. Double-belted curtains on the front and rear of the sweeping head contain the circulating air flow to assure debris transfer with minimal fugitive dust particles.

In contrast to mechanical broom sweepers, the Schwarze A4000 sweeper collects and retains the micron-sized contaminants that accumulate on roads and streets. Recent studies emphasize the importance of removing these "PM-10 fines" due to the non-point source pollutants that contribute to the stormwater runoff stream. Using the regenerative air Schwarze A4000 sweeper results in a cleaner street and a cleaner environment.
