Ceiling fans are based on the technology of classic fans designed to assist with ventilation in residential and commercial spaces. Their discreet exterior design and rounded shape make these products ideal for ceiling installation, though they work just as effectively when installed in a wall. Ceiling fans 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. They are available in several front panel styles and, depending on the model, in up to three sizes: ø 100, ø 125, and ø 150 mm. They are characterized by quiet operation, low power consumption, high efficiency, and reliability, which is why selected models come with a warranty of up to 5 years. Individual fans have additional features such as: motion sensor, humidity sensor, timer (shut-off delay), and photocell. Awenta ceiling 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.
