The Ultimate Cordless Solution for High-Access Cleaning
The Numatic RSB140 (RucSac Battery) eliminates the biggest frustration for HVAC cleaning technicians. This is none other than trailing cables. The cordless backpack vacuum combines professional suction power with complete freedom of movement. This allows your team to work on ladders, scissor lifts, and in confined ceiling voids. After all, it eliminates the trip hazard of a mains tether.
Designed for agility, the RSB140 is the industry-standard for fire damper testing and cleaning. It allows engineers to move between multiple access doors across a site.
Why Choose the RSB140 for Ductwork?
- Safety at Height: Perfect for cleaning high-level extract grilles, pipework, and lighting rails. Without a trailing lead, operators can climb and manoeuvre without risking cable snags.
- Powerful 36V Lithium-Ion Battery: Delivers over 35 minutes of continuous runtime on full power (or 60 minutes on low). This provides ample time to clean multiple fire dampers or AHU chambers on a single charge.
- Lightweight and Ergonomic: Weighing 7.3kg, the machine features a breathable, ergonomically adjusted harness. This distributes weight across the hips and shoulders. The weight distribution reduces operator fatigue during long shifts.
- Commercial Grade Suction: Despite being battery-powered, the 250W motor delivers consistent airflow (20L/sec). This ensures that heavy dust and debris found in ventilation systems are captured.
Smart Features for Professional Use
- Hand-Control Module: An integrated switch on the harness allows operators to turn the unit on/off without reaching behind them. This saves battery life between dampers.
- Off-Board Charging: Batteries can be swapped out in seconds. (We recommend carrying a spare battery for all-day operation.)
- 6L Capacity: A generous dust capacity that balances runtime with weight. It uses easy-to-change HepaFlo bags for clean disposal.
