WHAT ARE THE APPLICATIONS OF MANUAL DAMPERS?

Manual dampers cannot be operated remotely. That's why they're ideal for smaller locations, so the operator can easily access and regulate the position of the damper. Common applications of manual HVAC system dampers include:

  • Airflow circulation and exhaust system control in commercial kitchen hoods;

  • Conditioning supply air before it enters the space of buildings;

  • The outdoor airflow control for ventilation systems;

  • Balancing temperature for individual rooms or zones within a facility.

Manual dampers may also be used to control supplemental heating systems, such as radiant floor heating and baseboard heaters. They can be installed in place of an existing damper or as a stand-alone unit.
