KT-916 Commercial HVAC Negative Air Machine Portable High Suction Duct Cleaning Vacuum 50 Meters Reach

Specification

Discover the KT-916, an ultra-compact negative air machine purpose-built for professionals who demand hospital-grade air scrubbing in a footprint small enough for passenger elevators. At its heart sits a precision-balanced 2,200-watt turbine that generates 3,200 Pa of sustained suction, pulling drywall dust, sawdust, mold spores and even fine textile lint through an 80 mm lightweight suction hose that stretches up to 50 metres without kinking.

The entire chassis tips the scale at just 82 kg and rides on non-marking stair-climbing wheels, so one technician can roll it from basement mechanical rooms to penthouse air handlers without extra crew. A quick-lock drum holds three disposable 3-layer micro-fiber bags rated to 99 % efficiency at 1 µm, while a transparent inspection window lets operators see fill levels at a glance.

Smart electronics include soft-start circuitry to prevent breaker trips, an integrated hour-meter for accurate job costing, and a color-coded filter alarm that flashes before airflow drops below OSHA guidelines. Dual voltage 110–240 V auto-switching means you can plug into any outlet worldwide without rewiring. Whether you are clearing post-renovation debris, prepping ducts for hygienic food-grade certification, or maintaining negative pressure during asbestos abatement, the KT-916 delivers industrial performance with the agility of a shop-vac.
