Based on field tests, Mineflat delivers more airflow for a given length of ducting due to a lower leakage coefficient because of the patented stitch-weld process. Mineflat is colour coded based on the diameter of the duct to easily identify sizing. All sizes manufactured in 5, 10 and 20 metre lengths with some also manufactured in 50 metres. Joining mechanism is the skirt connecting method consisting of eyelets and a skirt, enabling connection with Mineflex.
