Regenerative Sweepers

Schwarze manufactures 5 models of Regenerative air sweepers to meet your specific sweeping needs.

The Schwarze model A7000 street sweeper is a heavy-duty, chassis-mounted, regenerative air sweeper with an 8.4 cubic yard hopper.  As one of the largest, most powerful air sweepers in existence, the Schwarze A7000 sweeper is an ideal choice for use in a wide range of demanding road sweeping applications.

The A7000's blower system generates a high velocity air column, which is propelled into the top of the sweeping head through a 14-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. This 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 14-inch suction tube.

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 escape of fugitive dust.

In contrast to mechanical broom sweepers, the A7000 sweeper collects 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 they contribute to stormwater runoff. Using the regenerative air Schwarze A7000 sweeper results in a cleaner street and a cleaner environment.

We also offer the A-4000, A-8000, A-9000 and DXR.

The A-4000 is the little brother to the A-7000.  Its basic systems and principles are exactly the same, it is just downsized to fit a smaller (under CDL) chassis.  It features a 4.3 cubic yard debris hopper.  For more specific details, please click here.

The A-8000 is a cousin to the A-7000 and features a hopper that is designed to dump to the side at operator controlled heights between 36 and 118 inches.  For more specific details, please click here.

The A-9000 is the big brother of the A-7000.  It provides all the benefits of the A-7000 with a debris hopper capacity of an amazing 9.6 cubic yards.  For more specific details on the A-9000, please click here.

The DXR is the Worlds most advanced Regenerative air Sweeper.  By utilizing a system of cartridge filters to filter 100% of the sweepers airflow, the need to use water during the sweeping process is eliminated saving valuable natural resources and allowing the operator to stay on the route longer.  For more detailed info, please click here.
