KT 928 Long Reach Duct Cleaning Machine 45m Hose Adjustable Brush

Meet the KT-928 Long-Reach Duct Cleaning Machine-the mobile powerhouse built for commercial, industrial and high-rise projects where distance, height and tight bends are the daily norm. A 45 m crush-proof, anti-static hose stretches from rooftop HVAC units to basement fan rooms without extra extensions, while its lightweight yet durable outer jacket glides smoothly over metal edges, insulation and fire dampers.

The heart of the system is a reversible, variable-speed drive that spins interchangeable nylon or brass brushes from 0 to 1 000 RPM. Choose soft brushes for delicate flex-duct or aggressive bristles for welded steel mains-four diameters (300, 400, 500 and 600 mm) are included and swap in seconds with tool-free twist locks. Forward and reverse rotation dislodges debris from both directions, preventing clogs and ensuring complete particulate removal.

Four quick-connect nozzles further expand versatility: a dust-extraction head pairs with negative-air machines, a high-velocity air knife blows light debris forward, a misting tip injects sanitizer, and a scraping cone tackles stubborn grease. All attachments click onto the same quick-coupler, so one technician can adapt on the fly without returning to the truck.

The compact 12 kg main unit rolls on oversized wheels, climbs stairs effortlessly and stores upright in a service van. Contractors report cutting large-duct cleaning time by 50 % and winning repeat business thanks to the visible, measurable airflow improvements they can document immediately after service.
