Depending on the choice of bearing material, the damper will be equipped with a round or square axle.
On Halton UTK/C dampers with standard bearings (BE=ST) , the damper will be equipped with a square 15×15 mm galvanised steel axle.
On heatproof design Halton UTK/C dampers, and on all dampers with AISI 316/304 or bronze JN5 bearings (BM=AS, BM=SS or BM=BR) a round Ø15mm AISI 316 stainless steel axle will be used.
The product models MD=I and MD=J have a double sheet casing with mineral wool insulation. The insulation thickness is 20 mm.
The Halton UTK damper is available equipped with either manual adjustment or actuator operation.
The adjustment and control arrangement options are:
|Adjustment and control options||Code||Note|
|Manual handle adjustment||MO = MA|
|Manual extension bar adjustment||AC = BA||Handle extension arrangement|
|Actuator operation||MO=||See tables below|
The damper actuator is selected from the list below according to the
operating voltage, control arrangement and the required torque of the damper.
The torque of the selected actuator can be higher than the required torque of the damper.

The Halton 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 Halton 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).
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.
The casing and blades are made from galvanised steel (or stainless steel AISI 316).
The blade gaskets are of silicon (or EPDM- rubber).
The drive shaft socket is of galvanised steel with self-lubricating slide bearings.
The bearing shall is from an alloy of polyamide and molybdenum sulphide (or stainless steel AISI 316 or stainless steel AISI 304 or bronze).
The damper is installed into rectangular ductwork in compliance with EN 1751, or in circular ducts D=100 … 1250 mm in accordance with EN 1751.
The damper meets the tightness requirements of EN 1751 class 1.
The casing of the damper meets the tightness requirements of EN 1751 class B.
The damper is suitable for either manual adjustment or actuator operation.
