Description

USE
Supply and exhaust ventilation systems in premises with high requirements to the noise level and with limited space for mounting. Possibility of space-restricted installation above suspended ceilings. Compatible with Ø 100–250 mm air ducts.
DESIGN
The fan casing is made of aluzinc. For easy installation and operation, the top cover of the fan is secured with a special lock. Heat- and sound insulation is made of non-combustible 50 mm mineral wool layer. To ensure better noise absorption, the inner surface of the insulation is made of a perforated metal sheet. The round connecting spigots are rubber sealed.
	SPEED CONTROL
	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.
MOTOR	MOUNTING
High-efficient direct current EC motor with external rotor and forward 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 fans are designed for connection to round air ducts. The fans are to be installed at an air duct junction. 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 with respect to the air flow direction indicated by the arrow on the fan casing. While mounting the fan provide enough access for servicing and repair operations.
