I want supply and extract air valves other than those in your product range. Can I use other types?

Yes, you can use supply and extract air valves other than those included in Flexit’s product range. However, please note that our design drawings and settings are adapted to Flexit valves. If other valves are used, the airflow rates must be measured and the ventilation system must be rebalanced on site to ensure correct operation and proper air distribution.
