Bernardo PU Suction Hose Ø150 mm (6 m) with Steel Spiral
The Bernardo PU Suction Hose Ø150 mm (6 m) is a professional-grade flexible duct suitable for industrial extraction systems and woodworking. Made from transparent polyurethane (PU), a material extremely resistant to abrasion and bending, it features a galvanized steel spiral that ensures robustness and structural stability. Thanks to its high flexibility and crush-proof structure, the hose ensures a constant and regular airflow, even in complex installations or around curves. The transparency of the material allows for easy monitoring of chip and dust passage, facilitating maintenance. Perfectly compatible with Bernardo extractors and systems, it is the ideal choice for joineries, workshops, and industrial laboratories that demand reliability and long-lasting performance.

Frequently Asked Questions
What is the difference between PVC hose, PU spiral, and PA spiral?
Rigid PVC hose: economical, suitable for fixed installations with limited 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 should be 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 include: visible abrasion of the outer spiral, reduction in 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 used only for the final mobile section.
Are spare parts available?
Original spare parts available with 3–5 working days shipping. Customer support available in Italian.
