Choosing a portable fan

The most common question we are asked is 'which portable fan should I buy?'. This depends on the intended application, so here is a brief run down of what to look for when choosing a portable fan.

Using extractor fans to reduce the temperature inside buildings

The single most effective way to lower the temperature inside buildings is to fit extractor fans to expel hot air from the roof space.

Cooling a small factory or workshop using fans

For buildings upto approximately 1400m3 (50,000cu.ft.) roof extractor fans can provide simple low cost cooling using ambient (outdoor) air.

Fan assisted cooling for medium to large commercial buildings

Because we live in a temperate environment, outside air can be used to cool medium to large commercial buildings, such as factories, workshops and warehouses in all but the hottest spells.

Axial fans can be used to remove hot air, supply cooler outdoor air, and produce air movement inside, creating a comfortable working environment without resorting to air conditioning.

Calculating the fan capacity required for ventilation

The rate of ventilation for an area is normally expressed in ‘air changes per hour’, i.e. the number of times per hour that the entire air volume of the area is changed. The rate depends of the type of room and the activity being undertaken.

Multiplying the air changes per our by the volume of the area, will produce the airflow required.
