Warranty Conditions
For the warranty conditions, please contact our Systemair colleagues in your respective country.
Before installing the FGS, its functionality must be tested as per chapter “FGS Functionality Check”
DO NOT INSTALL A NON-FUNCTIONING FGS!
Changes to the functionality of the FGS, caused by transport or installation, aren‘t reclaimable after installation
(deformations, damages, mechanical damage of the sealing material, foreign objects which can constrain the blades
movement, improper handling of the activating mechanism, etc.).
Operating Conditions
FGS air transfer grille can be dened as re shutter for overpressure ventilation without duct system in the place
where it’s needed to create an opening in borders of a re area or compartment. In case of re, the air transfer grille
functions as a re safety element and by closing, it prevents re and smoke from expanding to the next compartment
zone during the maximum performance time.
They are intended:
• for installation in places which are protected against weather disruptions.
• for ventilation distributing air without any mechanical or chemical contamination.
• for maximum air ow velocity 12 m/s.
• for storage temperature minimum -20 °C and maximum 50 °C.
In a standard design all manually and actuator operated Air Transfer Grilles are equipped with a thermal fuse which,
after reaching or exceeding 74 °C (manually operated, ±2 °C) or 74 °C (actuator operated, ±2 °C), activates the spring
which closes the damper blade.
From the noise perspective all FGS air transfer grilles are passive. Increased noise can only be heard
when the dampers is being closed or opened in case of an inspection or re.
