Top Quality Round Volume Control Dampers For HVAC Air Duct Supplier 

Round Volume Control Dampers
 

  1. Product Introduction

SuperAir Round Volume Control Dampers are equipped with a manually adjustable damper blade with regulating deivce . By adjusting the damper blade, the flowair can be controlled manually via the galvanised spiral ducts. The different sizes ensure a perfect connection of the damper to the galvanised spiral ducts. In addition, the Round Volume control Dampers can be equipped with good quality rubber gaskets  which guarantees an airtight connection to the spiral ducts. Just like the spiral ducts, the damper meets the strict air tightness class D requirements, which guarantees that you can install an optimized ventilation duct with high quality spiral ducts. You insert this spiral duct attachment into the duct. No additional connection piece is therefore required for connection.
Round Volume Control Dampers are ideal for use in branch duct lines for adjusting supply or return air volume. Typical uses are for rooms that get minimal use and can be closed off for extended periods of time or rooms that need different amounts of airflow in the summer and winter. You can easily use this Damper with vent system HVAC parts.
