Extractor fan – Blauberg ISO-K 315 4E for commercial kitchens

Hot air extraction with sound insulation

Blauberg ISO-K 315 4E sound-insulated centrifugal extractor fan for extracting hot, heavily contaminated air in professional settings. It is designed for 315 mm round ducts and is used in industrial kitchens, bakeries and technical departments where high airflow and noise reduction are required. The robust galvanised steel casing incorporates internal insulation made from 50 mm non-combustible mineral wool.

The 230 V single-phase AC motor draws 304 W and 1.84 A, with a maximum flow rate of 1970 m³/h and a sound pressure level of 46 dB(A) at 3 m. It operates between -20 °C and 110 °C, with fire resistance up to 120 °C for 60 minutes. The unit features a centrifugal impeller with backward-curved blades, IP54 protection and a frame with integrated vibration dampers. The accessible housing facilitates maintenance and periodic inspections of the fan.
