KT-926 Portable Air Duct Cleaning Machine 30 Meter Reach 50-800mm Ducts

The KT-926 rewrites the rules for large-scale duct maintenance without the large-scale footprint. At just 35 kg and with compact 440 mm × 240 mm × 320 mm dimensions, the unit slides into service elevators and through standard doorways, yet its 30 m working radius covers entire hospital wings or shopping-mall risers in a single setup. Four quick-lock brushes-ranging from 50 mm to 800 mm-snap onto the flexible shaft in seconds, allowing one technician to jump from office branch lines to main supply trunks without downtime.

A 550 W variable-speed motor drives the nylon head from 200 rpm for light dust to 1 400 rpm for carbonized kitchen grease, while a stepless dial on the pistol-grip remote lets operators feather torque in real time. The 15 m chemical-resistant hose can be extended to 30 m with optional couplers, reaching rooftop fans or basement returns without relocating the base unit. Oversized rear wheels and a front caster provide zero-turn agility around corners, and the onboard accessory tray keeps brushes and nozzles organized between jobs.

After cleaning, the quick-drain valve purges residual water in seconds, and the cable reel winds itself automatically, eliminating tangles and manual wrap-up. By combining ultra-long reach, tool-free adaptability, and true portability, the KT-926 slashes labor hours, improves indoor air quality, and helps facilities pass ASHRAE inspections with minimal disruption.
