How many kva required for fan?

The kVA required for a fan depends on its motor size and efficiency. Typically, a standard ceiling fan may require about 0.1 to 0.5 kW, translating to approximately 0.125 to 0.625 kVA (considering a power factor of around 0.8). For larger industrial fans, the requirements can be higher, depending on their specific design and application. Always check the manufacturer's specifications for the exact power ratings.
