used (accessory on request).
INTRODUCTION
QXD is a centrifgual fan for built-in installation, designed to ensure air extraction in small/medium-sized rooms
such as bathrooms, toilets and kitchens. Suitable for air discharge through long length ducting. Main extraction
through front cover, additional extraction though side inlet (fig.1).
TECHNICAL SPECIFICATIONS
• Material: High quality, impact and UV-resistant technopolymer, colour RAL 9010.
• Design front cover removable for cleaning without the use of tools.
• Integral air-tight shutter to prevent the return of odors or cold external currents when the unit is off.
• Additional side inlet Ø50mm for secondary air-extraction from adjacent rooms or direclty from the toilet
bowl.
• Removable filter to protect the impeller and the motor from dust.
• Sound proof foam for acoustic comfort.
• Highly quality forward-curved impeller for high performance and top silence.
• Single phase 2-speed motor with integral thermal protection.
• Motor mounted on ball bearings that guarantee a longer product life cycle (30.000h) and suitable for cold
climates.
• The fan is double insulated: no earth connection is required.
• Suitable for continuous or intermittent operation.
• IPX5 degree of protection.
• Power supply 220V to 240V~ 50/60Hz.
VERSIONS
STANDARD
The fan is operated using a separate ON/OFF switch or via a light switch (fig. 16A-16B).
WITH TIMER (over-run)
The fan is provided with a timer circuit which is adjustable from aprox. 1 minute to 25 minutes via trimmer
(fig. 17C). Operation: connected according to the diagram in fig. 17A-17B, after the light is switched on, the
fan activates with a delay of max 1.5 seconds. After the light is switched off, the fan continues to function
for a pre-set period of time.
WITH HUMIDISTAT & TIMER
The fan is equipped with a humidity detector, whose threshold is adjustable from 50% to 95% Relative
Humidity, and with a timer which is adjustable from aprox. 1 minute to 25 minutes via corresponding trimmer
(fig. 17D). Turn the trimmer HY completely clockwise and the humidistat function is deactivated.
Automatic humidistat operation: connected according to the diagram in fig. 17A-17B, when the percentage
of Relative Humidity exceeds the pre-set intervention threshold, the fan starts up automatically. When the
percentage of Relative Humidity goes below the threshold, the fan continues to function for a pre-set period
of time.
Operation with switch connection: connected according to the diagram in fig. 17A-17B, after the light is
switched on, the fan activates with a delay of aprox. 1.5 seconds. After it is switched off, the fan continues
to function for a pre-set period of time.
Attention: when the relative humidity level is higher than the pre-set threshold, automatic operation with
humidistat has priority over manual operation, or rather the fan cannot be stopped via switch.
The versions Standard, Timer and Humidistat & Timer are also available in the "Silent" configuration,
delivering optimised performances for top acoustic comfort.
