Aerobic fan exhaust fan tubing pipe pipe, 80 cm in diameter, 100 cm flute

Thank you for your personal approval of our product, the lack of individual feedback, the fact that the pipe is machine tailoring, the fact that computer data are set for tailoring, which is very precise and needs to be measured in a smooth manner. Since it is not possible to move to a very direct installation when you are installed, it is important to measure the physical distance at the time of purchase and to reserve around 20-30 cm, so that it is easier to install whether it has an angle or bend.
