Blauberg Turbo 250 G Inline Mixed-Flow Fan Boost airflow and climate control in your greenhouse, grow room, commercial kitchen or bathroom with the Blauberg Turbo 250 G. This 250 mm inline mixed-flow fan delivers 1 070–1 360 m³/h of powerful ventilation while operating quietly at just 44–51 dB(A). Built for round-duct systems, the Turbo 250 G combines robust German engineering, energy-efficient performance and smart temperature-responsive control in a compact, low-flammability polypropylene housing. Key Features: High-pressure mixed-flow impeller for 1 070 m³/h (min) to 1 360 m³/h (max) airflow Integrated two-speed AC motor on sealed ball bearings with thermal overload protection Built-in speed controller plus external thermostat sensor (4 m cable) for automatic temperature-driven operation IPX4-rated casing and drive ensure reliable performance in humid, splash-prone environments Ultra-quiet design: 44 dB(A) at minimum speed and 51 dB(A) at maximum, measured at 3 m Compact, any-orientation installation fits tight plenums, false ceilings or standard duct runs Quick-release motor block for fast servicing without dismantling ductwork Applications and Benefits: Ideal for hydroponic setups, greenhouses and horticultural environments, the Turbo 250 G maintains optimum temperatures by ramping fan speed when heat spikes and slowing down as conditions cool—minimizing overcooling and reducing energy use. In commercial and residential bathrooms or kitchens, its low-noise profile and IPX4 protection keep air fresh and moisture controlled without drawing attention.
