The most noticeable difference of the new fans from their regular siblings is the casing with noise and heat insulation. Depending on modification the noise level of such fans ranges from 29 to 47 dBA which corresponds to the level of ambient noise (e.g. in an office space) well within the comfort zone of a human ear.
Just like the Box EC series presented earlier, Box-I EC feature energy-efficient EC motors are characterised with high performance of up to 11 190 m3/h and the minimum power consumption of 91 W.
The fans can be connected to a computer using a controller for automatic air flow rate regulation. If necessary, several units can be integrated into a single network with centralised control.
The model range includes various standard sizes enabling matching the fans with rectangular air ducts from 300х150 mm to 1000х500 mm.
The Box-I EC models can be used in supply and exhaust ventilation systems providing high performance and operation efficiency while meeting exacting noise requirements for outstanding occupant comfort.
