High efficiency, which they achieve at very low noise levels Its easy installation makes them a preferred choice in both injection and suction ventilation systems Can be mounted vertically or horizontally, without changing their characteristics Used in both domestic and industrial ventilation systems. High resistance to corrosion and weathering, make them a preferred choice in the construction of suction and discharge ventilation systems, which have shorter air ducts and have less resistance Voltage : 230V | Frequency : 50Hz | Power : 90W | Speed : 2300 D/ dak | Air flow : 735 m3/h | Sound pressure : 46 dB(A) | Protection class : IP44 | Insulation class : B (CL)
