FläktGroup LQAZ-28 Damper Installation guide

  • Hello! I've reviewed the Installation Instruction for the LQAZ-28 Damper. This document covers the damper's actuation using different types of actuators, provides commissioning guidelines, and specifies torque requirements. I'm ready to answer your questions about the installation process and specifics mentioned in this manual.
  • What actuators can be used with the damper?
    What is the maximum permissible pressure differential when the damper is closed?
    What is the maximum torque loading on the damper?

COMMISSIONING
INSULATION
External dampers are supplied with a cover over the lever actuator
system. This permits external insulation of the damper.
TORQUE
The table below specifies the necessary torque.
DAMPER ACTUATION
ACTUATOR
The damper can be actuated by means of the LQVZ-01 lever actuator
(accessory) or the LQAZ-11 damper actuator motor (accessory) as
shown in Fig. 1 and 2.
CAUTION!
When starting the fan, make sure that the intake
damper is open. The maximum permissible
pressure differential when the damper is closed
is 1000 Pa. Maximum torque loading on the
damper: 30 Nm.
