The Super RBS Brush & Air Wash System features the RBS-1500 rotary brush system, which has a redesigned cleaning tool. The redesign includes a new guide system that lets the user adjust the height of the brush from 3 inches up to 11 inches off the bottom of the duct, in 1-inch increments. The brush package now comes with four brushes instead of two. The brushes include two 24-inch brushes (one nylon and one silica carbide). The buyer gets to select the other two brushes, with a choice of 8-, 12-, or 18-inch brushes with either nylon or silica carbide media. The duct cleaning system can be used for ductwork that is 4 to 22 inches high.
