Bernardo PU Spiral Suction Hose Ø100 mm (6 m) with Steel Spiral
The Bernardo PU Spiral Suction Hose Ø100 mm (6 m) is a heavy-duty professional duct suitable for industrial dust collection systems and chip evacuation systems. Made of transparent polyurethane (PU) with an integrated steel reinforcing spiral, it combines excellent flexibility and robustness, ensuring a long service life even under intensive use conditions. Its flexible and crush-proof structure allows for easy installation even on curved paths, maintaining a constant and powerful airflow. The transparent material allows for visual inspection of chips and dust passing through, facilitating maintenance. Suitable for use with Bernardo dust collectors and systems, this hose is the right choice for woodworking shops, workshops, and industrial laboratories that require efficiency, durability, and maximum operational safety.

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 necessary mobility.
Does the hose diameter need to exactly match the dust collector outlet?
Yes — or use an adapter. 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 dust collector 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-to-collector connections in standard workshops (machine 2–4 m from the collector), 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 business days shipping. Customer support available in Italian.
