LOW PRESSURE CENTRIFUGAL FAN IN SOUNDPROOF CABINET WITH DOUBLE EEC MOTOR
MANUFACTURING FEATURES
• Impellers made of reinforced polyamide with fiber glass.
• range fans assembled in soundproof cabinets with thermo-acoustic insulation, Bs1d0 fire class on the supply panel.
• Fan assembled on antivibration mountings.
• Connection gland included.
• Motor fixing with an exclusive system designed by Casals through flexible arms and silent blocks to avoid vibration. Flexible arms in compliance with the ROHS 2002/95/EC Directive (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipments).
• PM brushless motor (permanent magnets), synchronous, electronically commutated, high efficiency and low sound level. Specially designed for fans with electronic operation and control in deported box IP65.
Working range: from 400 to 1200-2000rpm (depending on the models)
Motor with IP54 protection and class F insulation. IP 65 drive case
Power: 220V ± 10% single phase
Power frequency: 50 / 60Hz
Operating temperature range: -20ºC to 50ºC
Speed control through signal 0-10V or PWM
• Fans can run separately or simultaneously.
APPLICATIONS
Designed for inline installation, indoor or outdoor assembly, they are suitable for:
• Air renewal in buildings and industries.
• Industrial and professional kitchen hood. Use in supply or extraction with prior fat filtering.
• Maximum working temperature: 50ºC.
UNDER REQUEST
• LG0 position.
• Impeller made of galvanized sheet.
* All data are referred to a single working fan. If both fans are working at the same time, data should be twice (x2) except for weight.

MANUFACTURING FEATURES
• Safety start-stop switches according to IEC 60947-1 and IEC 60947-3.
• IP65 and always equipped an auxiliary contact.
• Useful for switching off the current before handling the fan.
*Máx. thermal current air (A)
MANUFACTURING FEATURES
• Speed remote controller for EEC motors.
• Adjusts the flow rate in a range from 0 to 100% at a maximum distance of 10m.
• It can be recessed or mounted on a wall. Can be installed outdoors.
• Working temperature from 0 to 40ºC.
WORKING FEATURES
• Electronic system designed and developed for automatic control of Twin-fans, like TWIN QBK and TWIN QBK POWER.
• The REG TWIN control can be fitted within the Twin-fan housing or at any desired location of operation within the same building. The MODBUS communication protocol is integrated in the REG TWIN control.
• When REG TWIN is set to operate in AUTO mode, each fan will be running for a preset period of time interval (12 hours). In case of failure of any of the fan, REG TWIN automatically starts the Stand-By fan, simultaneously gives signal to the user about the faulty fan.
• An other function of REG TWIN is BOTH FANS RUNNING mode, to run both fans consequently to supply twice the normal air volume.
• Only suitable for single phase and electric motors (EEC).
CHARACTERISTICS
• Power supply: from 80 to 250 V. a.c. or d.c.
• Relay contacts current: 3 A 250 V. a.c. (For external intensities and three-phase motors an external contactor is necessary)
• Working temperature: from 0°C to 50°C.
• Storage temperature: from -25°C to 85°C.
• Relative humidity: max. 95% without condensation
• Dimensions: 104 x 93 x 25 mm.
CONNECTION OPTIONS
• Inside the unit (not connected).
• Attached outside the unit (the IP must be taken into account).
• Remote.
APPLICATIONS
This kind of control can be used to commutate a couple of motors to work in auto change over mode or simultaneously.
In case of TWIN QBK, a common application is in high temperatures environments (in the desert for example) where fans run in change over mode to avoid fan overheating problems.
