The unit uses a highly efficient backward curved centrifugal motor
impeller set and is designed for continuous 24 hour use. Four settable
speeds can be configured to change these speeds based on an integrated
sensor or separate switch inputs (not supplied). The unit will run
at a normal flow rate until the humidity sensor or external switch input
trigger a speed change. In the case of the switched live and digital inputs,
the units will perform a step change in speed to the appropriate level.
In the case of the analog inputs and humidity sensor, the unit can be
programme to give a proportional response to the change in conditions.
The extracted air is replaced through natural air flow through the gaps
around doors and windows, trickle inlet slots, or best of all, the Manrose
Puro Filtered Passive Vent Kit (DCT4565) with typhoon cowl that has an
effective aerodynamic area of 3000mm
