Technical characteristics
- Sound level : The acoustic spectra are indicated in dB(A) above the characteristic curves: radiated, suction and discharge sound power. The radiated and suction sound pressures at 1 m in free field are also given in the table of types.
- Design : EC centrifugal fans with small footprint for high flow and pressure. Designed to be inserted directly into duct networks for multiple uses (commercial, industrial and residential).
- Motor : High-efficiency, economical EC motor with LongLife ball bearings (30,000 hours).
- Space requirement : Reduced and easy to assemble thanks to an in-line air passage. Eliminates elbows and other complicated deviations.
- Connections : Adapted to standard conduit diameters, installation possible in all positions.
- Maintenance : Easy without dismantling the duct network by simply removing the fan unit.
- Motor protection : Integrated electrothermal protection for the EC motor and its regulation.
- Regulation : Double speed as standard controlled by external MVB type switch (accessory).
Description of components
- Enclosure : Removable thanks to a double lever closing system, allowing the removal of the fan unit. All parts are made of shockproof synthetic material (colour: light grey).
- Turbine : Optimized for high pressure and high flow rates, made of high-quality synthetic material. Quiet and dynamically balanced.
- Motor : EC motor with external rotor and variable speed, IP 44 protection, tropicalized, mounted on ball bearings, maintenance-free and interference-free.
- Electrical connection : Large external terminal box (IP 44), adjustable in all positions.
