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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the hose diameter need to exactly match the extractor outlet?\u003c\/summary\u003e\n\u003cp\u003eYes — 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow long does a spiral hose last in professional use?\u003c\/summary\u003e\n\u003cp\u003eIn 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 at the joints.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the 6 m length sufficient for most systems?\u003c\/summary\u003e\n\u003cp\u003eFor machine-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 only for the final mobile section.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre spare parts available?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working days shipping.
