In summer without air conditioning, an electric fan is a necessity.
Tips
usage
电扇 is the standard everyday word for an electric fan - also written 电风扇 with no change in meaning. Don't confuse with 扇子, the hand-held folding fan, or 排气扇, an exhaust fan.
memory
电 = 'electric' + 扇 = 'fan'. Note 扇 is a polyphone: shàn (noun, 'fan') vs. shān (verb, 'to fan / fan flames').
