Seal your hose properly — sized automatically to match the bore you selected. We’ve added 2 — one for each end of the hose. Adjust if you need more or fewer.
The Flamex B-F se is a flame-retardant polyurethane extraction hose, built for wood dust and chip extraction in busy workshops. Lightweight, highly flexible and crush-resistant, it links table saws, sanders, planers, thicknessers and CNC routers to your extractor or ducting run — and its clear wall lets you spot blockages and flow at a glance.
Because wood dust is combustible, the wall is flame-retardant to DIN 4102-B1 and the hose is approved to the German wood-trade standard Holz-BG (BGI 739-2). With the embedded steel spiral earthed, it also meets TRGS 727 for the aspirated transport of flammable dusts — the reassurance you want when moving fine timber dust around a workshop.
Constructed as a PU film hose with an embedded spring-steel support coil and a hard-wearing polyester-polyurethane wall (approx. 0.5 mm between the spirals), it runs from -40 °C to +90 °C (short peaks to 125 °C) and compresses roughly 1:4 for easy storage. Available in bore sizes from 38 mm to 400 mm in 10 m and 15 m coils.
Note: ATEX / explosion-zone suitability must always be assessed for your specific installation by the operator.

Light enough to reposition all day, flexible enough for tight machine hook-ups, and rated for the fine, combustible dust that timber, MDF and plywood throw off. It connects to most woodworking machines — including table saws, bandsaws, planer-thicknessers, spindle moulders, drum and belt sanders, CNC routers and downdraft benches — or runs as flexible extraction ducting between machines and a central extractor or dust collector. The abrasion-resistant wall shrugs off the shavings and grit that wear out cheaper hose, and earthing the spiral keeps static under control on fine-dust runs.
