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	MODIFICATIONS AND OPTIONS
Galvanized steel casing internally filled thermal- and sound-insulating layer.The connection spigots are equipped with rubber seals.Fixing brackets for easy mounting.	FR1: smooth speed controller adjustable from 0 to 100 % and power cable with mains plug.W1: power cable with mains plug.
MOTOR	SPEED CONTROL
High-efficient direct current EC motor with external rotor and backward curved blades.EC technology meets the up-to-date requirements to energy-saving and controllable ventilation and provides up to 35 % energy saving as compared to asynchronous motors.EC motor ensures totally controllable speed range for the fan and has integrated overheating protection with automatic restart.EC motor has no friction and wearing parts as capacitor und brushes. Instead a maintenance-free EC controller electronic circuit board is used.The impeller is dynamically balanced.The fan is compatible with 50 Hz and 60 Hz power mains and the maximum speed does not depend on power mains frequency.	The fan speed is controlled with a 0–10 V control signal from the following sources: integrated or external speed controller controller with sensors central BMS system. The control signal value changes depending on air temperature, pressure, smoke concentration and other parameters.During signal value change the fan with EC motor correspondingly changes the rotations speed and delivers required air volume to the ventilation system.The computer central building management systems (BMS) enable integration of several EC motors in network and precise individual operation control for each fan.
MOUNTING
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.
