A riding sweeper (10) having a dumpable hopper (24) divided into a debris chamber (44) and a clean air chamber (56) includes a filter (58) disposed between the two. A continuous dust back flushing control system (64) is disposed in the clean air chamber (56) for periodically back flush cleaning. The air compressor (66) that supplies the air manifold (70) is located in the clean air chamber (56) as well as the motor (68) for driving the compressor (66). A pressure switch (94) measures the air pressure within the air manifold (70) and valves (96A, 96B, 96C) trigger the back flushing nozzles (76, 78, 80) when the air pressure in the air manifold (70) reaches a predetermined level. A 12 VDC electronic sequencer (92) chooses the valve and thus the nozzle to fire. The machine power source drives the compressor motor (68) and the sequencer (92). |
