Classic fans are designed to assist with ventilation in residential and commercial spaces. They are characterized by quiet operation, low energy consumption, high efficiency, and reliability, which is why selected models come with a warranty of up to 5 years. Primarily used as wall-mounted fans, they work just as effectively as ceiling fans. Classic fans are available in over a dozen front panel designs with varied styles and, depending on the model, come in sizes of ø 100, ø 120, ø 125, and ø 150 mm. Almost all models are designed to accommodate a check valve that prevents backdraft, which occurs due to strong gusts of wind or when the temperature outside the building is higher than inside. Individual fans have additional features such as: a motion sensor, a humidity sensor, a timer (shut-off delay), a photocell, or a pull-cord switch. Awenta classic fans meet the IPX4 protection class, allowing for uninterrupted operation when exposed to water splashes from various directions at a rate of up to 10 liters per minute.
