Bernardo Spiral Suction Hose Ø160 mm (6 m) with Steel Spiral
The Bernardo Spiral Suction Hose Ø160 mm (6 m) is a professional duct for industrial and woodworking dust extraction systems, designed for operational efficiency and long life. Constructed from professional-grade transparent plastic material, it allows for immediate visual inspection of chip and dust flow. The galvanized steel spiral integrated into the structure offers high resistance to crushing, twisting, and abrasion, while maintaining excellent flexibility. With its 160 mm diameter and 6-meter length, it is suitable for connecting Bernardo machinery, fittings, and joints, ensuring constant airflow and stable suction. Suitable for workshops, laboratories, and professional extraction systems, this hose combines robustness, transparency, and ease of use in a single professional-grade component.

Frequently Asked Questions
What is the difference between PVC, PU spiral, and PA spiral hoses?
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 being extracted and the required mobility.
Does the hose diameter need to exactly match the extractor outlet?
Yes — or use an adapter. A reduction in diameter causes a loss of flow and can cause the circuit to 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 the intensity of use. PU is the most abrasion-resistant. Signs of wear include: visible abrasion of the outer spiral, diameter reduction due to crushing, air leaks at joints.
Is the 6 m length sufficient for most systems?
For machine-to-extractor connections in standard laboratories (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 used only for the final movable section.
Are spare parts available?
Original spare parts available with 3–5 business days shipping. Customer support in Italian available.
