Bernardo PU Spiral Suction Hose dia. 120 mm – length 6 m
The Bernardo PU Spiral Suction Hose Ø120 mm (6 m) is a professional flexible hose made of transparent polyurethane (PU) with a galvanized steel reinforcement spiral, designed for maximum strength and durability in industrial dust extraction systems. Suitable for conveying chips, dust, and lightweight materials, it ensures smooth airflow and a long operational life even under intensive working conditions. Its flexible and crush-proof structure allows for easy installation on Bernardo machinery and fittings, maintaining high stability even on curved paths. The transparent material also allows for visual inspection of the flow, improving system safety and maintenance. Suitable for woodworking shops, workshops, and professional dust extraction systems, it combines strength, efficiency, and flexibility in a single, professional-quality product.

Frequently asked questions
What is the difference between PVC, PU spiral, and PA spiral hose?
Rigid PVC hose: economical, suitable for fixed installations with little flexibility. PU (polyurethane) spiral hose: flexible and abrasion-resistant — suitable for mobile use with coarse chips and metallic dust. PA (polyamide) spiral hose: more rigid than PU but resistant to higher temperatures and oils/solvents. The choice depends on the type of dust extracted and the required mobility.
Does the hose diameter need to exactly match the extractor outlet?
Yes — or an adapter is used. A reduction in diameter causes loss of flow rate and can make the circuit whistle. An increase in diameter requires a conical adapter. To maximize performance, use the same diameter as the extractor outlet for the entire length of the main hose.
How long does a spiral hose last in professional use?
In professional use with abrasive chips (metal, MDF, stone): 1–3 years depending on intensity of use. PU is the most abrasion-resistant. Signs of wear are: visible abrasion of the external spiral, reduction of diameter due to crushing, air leaks at joints.
Is the 6 m length sufficient for most systems?
For machine-extractor connections in standard workshops (machine 2–4 m from the extractor), yes. For longer distances or centralized systems, rigid PVC sections are used for the fixed path and the flexible hose is only used for the final mobile section.
