Function


FUNCTION




The UTK dampers are used to shut off, adjust or control airflow in ductwork in applications where damper leakage does not have significant importance.
In the closed position the UTK damper leakage class is 1 in accordance with the EN1751 standard.
In the open position the blades are turned in the direction of flow and do not cause significant pressure loss.

Damper sizes conform with the international standards EN 1505, EN1506 and ISO 1707 for rectangular and circular ducts.


The maximum operation temperature of a standard damper is +100°C (for optional models +200°C).

Installation


INSTALLATION




CODE DESCRIPTION
1 CASING
2 BLADE
3 MANUAL ADJUSTMENT HANDLE / ACTUATOR PLATFORM

Install the damper in the ductwork with the blades in horizontal or vertical position.
Fasten the damper in the ductwork using slip joints.

Optional models enable fastening the damper to duct flange by using bolts.
Drill holes in the damper flange if necessary (options L1 & L2).
Use a seal between the flanges in order to tighten the seam.

Fasten the circular connections by riveting or screwing.
