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.\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 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 external spiral, reduction of diameter due to crushing, air leaks at 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 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 only used for the final mobile section.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eSpare parts available?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 business days shipping.
