RD (flow controllers for PVC constant flow systems)

Flow rate controllers for constant flow systems for circular ducts. They can be used for both supply and extract air, with considerable ease of installation by simple interlocking. 

They are able to maintain a fixed flow rate under varying operating conditions, avoiding any adjustment or balancing on installation. 

Maximum temperature: 60 °C.

Execution
