✔️ OD 110 mm (4 1/3 in) spans 0 9 to 1 8 meters with valve

This sturdy extraction tube is a handy ventilator designed to snag dust, workshop smoke, and lab fumes before they drift into shared airspace. Shop owners and lab techs mount it above soldering benches or drying racks to keep breathing air clean without messy framing. The built in three step throttle flips between closed open and mid range so you dial in suction exactly where your crew works. You pick your preferred run length upfront and the self supporting sleeve locks into position without extra clips or tension wires.

✅ Corrugated polymer shell stands up to workshop scrapes
✅ Integrated louver stops reverse drafts when units power down
✅ Rigid inner coil holds diameter flat across sharp turns
✅ Stainless connector ring mates with 160 mm vacuum inlets

💡 Why does a flexible exhaust hose retain suction efficiency when routed through narrow ceiling cavities? A continuous helical support wire runs through the core to keep the tube open under negative pressure while the smooth outer jacket slides quietly past framing. - Heat resistant weave keeps wall rigidity intact during prolonged weld fume drawing - Anti collapse geometry preserves full airflow diameter across every steering angle - Snap fit flange locks tightly to prevent rattling when fans cycle on and off - Lightweight tube reduces mounting hardware load on suspended grid tracks
