Blauberg Iso-V EC 355

Supply and extract ventilation systems installed in premises with high requirements to the noise level.A perfect solution for various ventilation system configurations due to a special transformable casing design.Suitable for use as a component of a modular air handling unit.For arranging energy-saving and controllable ventilation systems.Compatible with Ø 315 up to 630 mm round air ducts or 500x500 up to 800x800 mm rectangular air ducts.

Compatible both with square and round air ducts.Connection to air ducts through flexible vibration absorbing connectors or connector-reducers of a matching section.External terminal box for connection to power mains.Mounting in any position in compliance with the air flow direction. Maintenance space must be provided.In case of outdoor mounting the fan may be equipped with the upper protecting cover (RSD-IV series) or the outer hood (AH-IV series) to be installed at air inlet/outlet.

Casing made of aluminium frame and removable aluzinc thermal and sound-insulated double-skinned sandwich panels.Casing internally filled with 20 mm non-flammable mineral wool.Position of the removable panels can be adjusted to inline air flow or 90° angle air flow.Due to corrosion-resistant and thermally insulated casing the fan is suitable for external use.The fan is compatible with square to square vibration absorbing connectors (AKV series) or square to round connector-reducers (ARV series), both available upon separate order.The round spigot of the ARV connector-reducer is rubber sealed for air tight connection.

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.
