MINE VENTILATION DUCTING
When it comes to mine ventilation ducting and tunnel ventilation, it is imperative that the underground ventilation system is of the highest quality to guarantee maximum effectiveness and safety. Unreliable and inadequate ventilation puts workers in danger – it’s not worth taking the risk. With Plascorp, you can rest assured that our mine ventilation solutions are some of the best in Australia.
Plascorp mining ventilation products are made from polyethylene woven coated fabric or polyester coated PVC to handle rock walls, faces and ceilings. Our manufacturing process incorporates our patented stitchweld process. This innovation gives vastly reduced air loss by way of top and bottom welded seams and has demonstrated a longer lifespan compared to others in the market.

TUNNEL VENTILATION DUCTING
Plascorp tunnel ventilation products are made of PVC coating reinforced with a polyester yarn that provides a high tear resistance and lower energy consumption. The ducting is lightweight, durable and extremely flexible and is used for tunnel ventilation during the construction stage and/or on a permanent basis. Available in various tensile strength grades plus optional fire retardant and antistatic properties to suit performance ranges.

MINEFLAT
Based on field tests, Mineflat mine ventilation delivers more airflow for a given length of ducting due to a lower leakage coefficient because of our patented stitch-weld process. Mineflat is colour coded based on the diameter of the duct to easily identify sizing. All sizes available in 5, 10 and 20 m lengths with some also available in 50 m. The joining mechanism is the skirt connecting method consisting of eyelets and a skirt enabling connection with Mineflex, hook and loop fasteners and even zippers.
Additional sizes and joining systems are available upon request.
