Description
USE
Supply and extract ventilation systems installed in premises with high requirements to the noise level.Suitable for limited mounting space.Unit design includes a possibility of space-restricted installation above suspended ceilings.Compatible with Ø 100 up to 315 mm round air ducts.
DESIGN
Galvanized steel casing internally filled thermal- and sound-insulating layer.The connection spigots are equipped with rubber seals.Fixing brackets for easy mounting.
MOTOR SPEED CONTROL
High-efficient electronically commutated direct current motors with backward curved blades. Such motors are the most state-of-the-art energy saving solution.Power consumption of EC motors is 35 % less as compared to standard motors.The fans with EC motors have excellent aerodynamic performance and low-noise operation.EC motors are featured with high performance and total speed controllable range.High efficiency reaching 90 % is the premium advantage of the electronically-commutated motors.The motors are equipped with ball bearings designed for at least 40 000 operating hours. The fans are controlled by means of a 0-10 V external control signal while the performance regulation is based on the feedback from the temperature, smoke and other sensors as well as other vital parameter settings.As the control signal changes the EC fan changes speed accordingly to supply the exact air amount required by the ventilation system.The maximum fan speed does not depend on the electric mains frequency enabling compatibility with both 50 Hz and 60 Hz networks.The fans can be easily combined into a single computer-controlled network.Special software allows for precise control over the operating parameters of the network units.
 
MOUNTING MODIFICATIONS AND OPTIONS
The fans are intended for installation in round air ducts. They are installed between the air ducts.The use of flexible connectors requires fixation of the fan on the building structure by means of supports, mounts or fixing brackets.The fan can be fixed in any position, taking into account the air flow direction indicated by the arrow on the fan casing.While mounting the fan provide enough access for servicing and repair operations.Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box. FR – built-in speed controller.
