The addition of a box fan helps lessen the strain on an air conditioning unit by aiding full force air circulation and helping the air to circulate more quickly.

Box fan energy consumption.

How much electricity does a box fan use. For example a box fan that s rated at 2 000 cfm will cool a room of 2 000 cubic feet in one minute. This high performance industrial fan can help users save money while reducing energy consumption in their homes and offices. This information is usually found on the back of the appliance or on a tag affixed to the cord.

Like all fans a box fan s power is measured by how much air movement it provides. The ideal power consumption for a fan without losses can be expressed as pi dp q 1. Energy costs of fans fans in general do not consume a lot of energy. Box fan power consumption tends to be pretty low.

Based on our calculations this means that it costs far less than 0 01 per hour to run making it extremely economical.

I was blown away with what i measured. What i discovered from my testing is that not only do air conditioners yes it s very obvious use more electricity than fans but they can use up to almost 9 to 10 times as much as a fan does.
