Vent Tube

Vent tube or mine ventilation duct can be manufactured for the ventilation (supply or exhaust) of mines, tunnels and portal shafts and can be used as a temporary vent line during construction or as a movable permanent installation. Vent tubing is available in round or oval configuration and has a 4 ply folded lockseam construction with a very smooth and airflow efficient interior surface. The tubing is corrugated to resist collapse from negative pressures in an exhaust application and is normally manufactured from a galvabond coated mild steel strip.
