FläktGroup LQVE Intake and exhaust air section for outdoor Installation guide

  • Hello! I've reviewed the installation instructions for the Fläkt Woods LQVE air section and LQAZ-11 damper actuator. This document provides details on the installation process, rotation limits for the actuator, and crucial commissioning steps, such as ensuring the intake damper is open. I'm ready to answer your questions about these products and their installation.
  • What is the maximum permissible pressure difference over the damper?
    What is the maximum torque for damper actuator?
    What should be ensured during commissioning of the fan?
