• Continuous Bending Capability: This air duct sweeping and vacuuming machine can pass through three consecutive right angle bends, shuttle freely inside the air duct, and clean without dead corners. Equipped with a 49.2ft/15m flexible shaft, dust suction filtration system and clean control system can be controlled separately, convenient for independent use.
• Multi Functional Design: This fresh air pipe duct cleaning machine adopts a sweeping and suction integrated design, which sucks the cleaned dust into the machine while sweeping, improving cleaning efficiency. The dust is sucked into a dedicated dust collection box, simultaneously perform dusting and suction to improve efficiency. Newly added dust blowing function, with strong wind and fast speed.
• Forward & Reverse Operations: Stepless speed regulation: 0-1400 RPM, suitable for various working conditions. According to the homework requirements, it can be adjusted in both forward and reverse directions to achieve 360 ° thorough cleaning without dead angles.
• High Quality Materials: EVA foam sealing with high sealing performance, suitable for pipe diameters of 1.97"-7.87" (50-200mm), effective sealing, and efficient dust suction. Selected aviation aluminum material joint, waterproof, rust proof, tensile and anti-fracture.
• Versatile Applications: Widely used for cleaning ventilation pipes in commercial and household fresh air systems. The pushcart design facilitates movement and makes machine handling easier.
