What is a Portable Fan?-ipanergy
A portable fan is simply a fan that is not permanently affixed to the wall or ceiling. Portable fans come in all shapes and sizes, from tiny battery-powered fans that can be held in the hand, to large box fans meant to ventilate a whole room. Using a portable fan can be a great way to keep the air moving, moderate the temperature of a room, and supplement the use of an air conditioner to save power.
There are a few different types of portable fans. These include personal fans, box fans, window fans, pedestal fans, and floor fans, among others. Personal fans may be the small, battery-powered handheld ones mentioned above, or they may simply be a small electric fan designed to sit on a desk, table, countertop, or dresser. Handheld personal fans sometimes offer a water misting feature as well, so as the fan spins, a light spray of water will help to cool the user. Electric personal fans often oscillate, but not always.
Box fans and floor fans are similar types of portable fans. A box fan is a large, square fan, generally about two feet (.6 meters) across, whereas a floor fan is often a round fan of a similar diameter. These fans are typically not capable of oscillating, but are more powerful than a personal fan and may be used to assist in cooling an entire room. A pedestal fan, conversely, is often a large portable fan on top of a height-adjustable pedestal. These fans are slightly smaller than floor fans, between one and two feet (.3 and .6 meters) in diameter, but usually oscillate and tilt, and are also capable of cooling a whole room.
