2000 Series Volume Control Damper
The 2000 Series is a high-performance control damper featuring an extruded aluminium aerofoil blade housed within a steel frame. It has exceptional leakage and pressure drop attributes for enhanced performance, realised through the Santoprene Dual-Durometer blade tip seal and stainless steel side jambs.
The damper provides precise control, particularly in natural ventilation systems, through direct linkage. This damper can be controlled manually or by an actuator.
Features
- Airfoil section extruded aluminium blades mounted within a rigid galvanised, flanged mild steel frame provides the basis for a low leakage, high performance volume control damper.
- Santoprene blade tip seals and Stainless Steel side jamb seals ensure class-leading leakage performance.
- Low friction bearings and substantial blade linkages afford quiet operation and low torque requirements.
- 2000 Series dampers can be mounted in vertical or horizontal planes
- Suitable for manual or motorised operation. Most standard motors can be factory-fitted if required
