Oscillating Fans

An oscillating fan can change the direction of its air flow, unlike a box fan or ceiling fan which has a fixed air flow. This allows it to cover more of the room space and provide better cooling and circulation. It is also more economical to use than an air conditioner, using just a fraction of its power consumption. The three main types of oscillating fan are the desk, pedestal, and tower. While the desk fan and pedestal fan are very similar in appearance and construction, the tower fan is very different to both of them.

The desk fan is one of the most common appliances of the last century and there is still a huge demand for them, despite the increasing use of air conditioning in the home and office. This has resulted in manufacturers creating many different styles and features over the years in order to stay competitive. However, the basics of the desk fan have remained the same, with each one having a fan blade disk, motor, cage and stand.

The stand of is typically short and the total height of the desk fan is usually less than two feet. The fan unit, including the cage and motor, rotates while the stand remains fixed. Most models rotate through an arc of ninety degrees but some have a slightly wider arc. There is usually a lock that stops the oscillating and fixes the air flow direction. Most models also have an adjustable neck allows the fan unit to be directed up or down.

The pedestal fan is very similar to the desk fan. The only the main difference is the wider base and longer stem that makes up the pedestal. Most models have an adjustable stem with a locking ring in the middle. Once the ring in unscrewed, the top half of the stem can be raised or lowered. They also have adjustable necks like desk fans. Pedestal fans with large diameter blades are often used in large rooms and warehouses, while desk fans are only strong enough to cover a small room.

The tower fan has more in common with an air conditioner than it does with a desk or pedestal fan. Instead of a blade disk, it uses the same barrel fan and vane system used in the wall unit of a split-system air conditioner. This allows the tower fan to have a small base but also requires that it be quite tall. Unlike a desk or pedestal fan, the fan unit does not move. Instead, motorized vanes rotate to direct the air flow around the room.

The blade diameter or length is a measure of how powerful the fan is and it is often printed somewhere on the package. The larger fans have a higher flow volume than the smaller fans. Despite the differences in design, one thing these oscillating fans have is their speed control. Some models have one fixed speed but most have three speeds. A well designed fan runs quietly at all speeds but some cheap fans develop vibrations and noises as their speed increases.

An oscillating fan will usually require some assembly straight out of the box. Parts of the base may need to be attached to the stand and may need to be secured with screws and a screwdriver. Some models have parts which snap together that make this task much easier. The fan cage may also need to be secured around blades. The cage often has two halves which are joined together by screws or tabs.

When deciding which oscillating fan to buy, check the length of the power cord to see if will be long enough to reach the powerpoint. Also look at the size of the grill to make sure that children will not be able to put their fingers through it and reach the blades. If the fan is going to be used in another country from the one it was purchased in, check that the power supply is compatible with that required by the fan.
