KT-928 Industrial Air Duct Cleaning Machine For Round And Square Vent Systems

The KT-928 turns labor-intensive duct maintenance into a one-person operation. Built around a rigid steel frame and mounted on a balanced cart with large rear wheels, the unit glides over thresholds and uneven floors, reaching rooftop or basement air handlers without extra manpower. Once positioned, the operator chooses from an interchangeable brush set-soft nylon for coated fiberglass, stiff polypropylene for galvanized steel-covering every diameter from 100 mm to 600 mm. A sealed variable-speed drive smoothly ramps rotation from 0 to 1 000 rpm, letting technicians feather light contact on thin liners or apply aggressive torque on baked-on debris.

Forward and reverse modes can be toggled from the pistol-grip handle or set to automatic oscillation, ensuring bristles reach every curve, elbow, and drop in complex duct layouts. The cart's telescopic mast doubles as a cable and hose boom, keeping 20 m of lightweight shaft off the floor and out of trip zones. After the job, quick-release couplings allow brushes to be swapped and rinsed in seconds, while the compact footprint rolls straight into a service van. By combining portability, tool-free adaptability, and robust construction, the KT-928 helps facility teams cut cleaning time, extend HVAC life, and meet indoor-air-quality standards with minimal downtime.
