Bernardo Spiral Suction Hose PU Ø100 mm (10 m) with Steel Spiral
The Bernardo Spiral Suction Hose PU Ø100 mm (10 m) is a professional flexible duct, designed for industrial applications and chip, dust, and processing residue extraction systems. Made of high-resistance transparent polyurethane (PU), with a galvanized steel reinforcement spiral, it offers an ideal combination of strength, flexibility, and durability. Resistant to crushing, abrasion, and torsion, it ensures a constant airflow and optimal performance even over long sections. The transparent material allows for easy monitoring of the suction flow, improving system safety and maintenance. Perfectly compatible with Bernardo extractors and systems, this hose is suitable for woodworking shops, workshops, and industrial environments that require professional quality and reliability.

Frequently Asked Questions
What is the difference between PVC, spiral PU, and spiral PA hoses?
Rigid PVC hose: economical, suitable for fixed installations with little flexibility. Spiral PU (polyurethane) hose: flexible and abrasion-resistant — suitable for mobile use with coarse chips and metallic dust. Spiral PA (polyamide) 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 a 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 the intensity of use. PU is the most abrasion-resistant. Signs of wear are: visible abrasion of the outer spiral, reduction in diameter due to crushing, air leaks in the 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 only for the final mobile section.
