Installation and Maintenance
Introduction
The four motorised inline damper models with run on
timers 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
100mm, 125mm, 150mm and 200mm.
Dimensions
Handling
Handle the units carefully to avoid damage and distortion
to moving parts.
