Note
Using BELIMO damper actuators
The actuators listed in this catalogue are intend-
ed for the operation of air dampers in HVAC
systems.
Torque requirements
When calculating the torque required to oper-
ate dampers, it is essential to take into account
all the data supplied by the damper manufac-
turer concerning cross sectional area, design,
mounting and air flow conditions.
