Keep your garage, workshop, attic, bathroom or kitchen fresh and free from odours, humidity and stale air with the MISTRO 300mm Shutter Exhaust Fan. Delivering a powerful 1350 m³/h airflow at 1600 RPM, this wall-mounted extractor is designed for spaces of 15–25 square metres. The stepless rotary speed controller lets you adjust ventilation from a gentle low hum to full power for rapid air exchange. Automatic metal louvers open when the fan is running and close by gravity when it stops, keeping out rain, dust and insects. Built from powder-coated galvanised steel, it withstands coastal humidity and winter weather. Thermal overload protection ensures safe operation by cutting power if the motor overheats, with a manual reset. Includes a safety grille. Ideal for workshops, garages, attics, warehouses, greenhouses and more.
