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 aspirated and the necessary 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 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 outer spiral, reduction in diameter due to crushing, air leaks in the joints.
Is the 6 m length sufficient for most systems?
For machine-to-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.
