Plastic ventilation channel 125 mm is used to move air in an exhaust or supply ventilation system. Channel length2 meters. The plastic air duct round 2020 is one of the elements of the Plastivent system. Can be used with other round elements. Also, using this channel, you can connect any of the exhaust fans of the Vents household series to a ventilation shaft.
Design
- channels are made of white PVC.
- section diameter 125 mm.
- channel length is 2 meters.
- plastic ventilation pipes are connected to each other using a connector of the appropriate diameter

Example 1 . For example, you need to select an air duct for a kitchen hood. The productivity is specified as 300 m?/h. The speed in the main section is assumed to be 5-6 m/sec. According to the table, an air duct with a diameter of 150 mm is suitable.
Example 2. It is necessary to select a side air duct from the main (root) section from the supply ventilation branch. The speed in the branches is assumed to be 3-4 m/sec. The productivity should be calculated at 100 m?/h. According to the table, a round air duct with a diameter of 100 mm is suitable.
