Are you considering buying fans? If so, why not consider a DC motor fan over an AC fan.
DC fans consume up to 70% less energy and run almost silently. Compared to AC fans that have the whirring noise when in use. The energy-efficient process keeps the motor cool, effectively improving the fan’s life span and further lowering running costs.
DC models allow more control over air movement with up to 7 settings compared to AC fans with only 3 settings. Yes DC fans are more expensive than AC fans but weighing up the energy savings, life span and noise factor the DC fan is certainly the better option overall.
