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 use an adapter. A reduction in diameter causes a loss of flow and can cause the circuit to 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 the intensity of use. PU is the most abrasion-resistant. Signs of wear include: visible abrasion of the outer spiral, diameter reduction 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-to-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 is used only for the final movable 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 business days shipping.
