KT928 Rotary Brush Air Duct Cleaning Machine For Circular And Rectangular HVAC Ducts

The KT928 Rotary Brush Air Duct Cleaner redefines versatility in HVAC maintenance by uniting professional-grade suction, multidirectional brushing, and user-centric ergonomics in one lightweight system. At only 9.8 kg, the unit can be lifted, positioned, and guided by a single technician, yet its compact frame conceals a robust motor that drives the brush head from 200 to 1,400 rpm. This stepless speed control lets operators match aggressiveness to contamination: soft nylon bristles for delicate aluminum flex duct, stiff polypropylene filaments for stubborn grease, or stainless-steel coils for mineral scale in commercial kitchen risers.

A 360° rotating joint enables the brush to sweep forward, reverse, and side-to-side without repositioning the machine, ensuring every seam, elbow, and blind corner is reached on the first pass. The integrated 5-meter anti-static hose stretches over obstacles and coils neatly onto the integrated reel for transport, while the ergonomic, vibration-dampened handle reduces wrist fatigue during extended sessions. A quick-lock collar allows brush heads to be swapped in under 15 seconds, so crews can move from 100 mm residential branches to 600 mm industrial mains without downtime.

Whether you are a facility manager restoring airflow in a hospital, a fire-safety contractor degreasing restaurant exhausts, or an energy auditor preparing ducts for thermographic inspection, the KT928 delivers laboratory-grade cleanliness with the portability and simplicity demanded by on-site professionals.
