With manual control valves, you can logically regulate the airflow in your spiral duct ventilation system. This allows you to manually determine the speed of the internal airflow of your ventilation system.
Installing a spiral duct is quite simple. The rubber seal on the control valves quickly and easily creates an airtight connection between the spiral duct and the valve. With the rubber seal, not much else is needed for installation.
