Installation and Maintenance
Introduction
The three motorised inline damper models are designed
for installation with Nuaire’s range of Ecosmart
Constant Pressure Variable Volume extract fans.
The units incorporate a fixed damper to set the trickle
ventilation flow rate and a wax type 230V driven
actuator to increase the flow rate to boost on demand.
Units are rectangular in section, manufactured from
pre-galvanised steel and designed to match duct sizes of
125mm, 150mm and 200mm.
Dimensions
Handling
Handle the units carefully to avoid damage and distortion
to moving parts.
