Techincal Information:

Low profile 100mm wide interlocking aluminium aerofoil blades ensure good aerodynamic characteristics for quiet operation and minimum pressure drops. 

All blades incorporate an edge seal to give an air seal performance as standard. 

Blades are interlocking and operate through a nylon geared drive which can be used with manual, electric or pneumatic control.

The frame work is fabricated from an extruded aluminium section square or rectangular with 40mm flanged connections to accept proprietary duct flanges or fixed within the AHU casing.

All dampers are supplied with a single square extended drive spindle as standard for connection to an electric or pneumatic controller. For manual control an optional hand locking quadrant can be fitted.

For damper sizes larger than 2000mm wide x 1200mm high multiple damper assemblies will be provided. All multiple arrangements require more than one control
