Free standing extractor fans

Types of free-standing extractor fans

A free standing extractor fan is a type of extraction fan system designed to stand freely and be positioned as desired. Unlike conventional ceiling or wall-mounted exhaust fans, free-standing extractor fans feature legs or a pedestal that allows them to stand upright on the floor. These portable extractor fans can be moved around to suit different needs. Typically, free-standing extractor fans have larger blades than standard extractor fans, resulting in higher airflow and more efficient extraction of air from enclosed or cramped spaces. The following options show some of the ways free-standing extractor fans can be used.

• Pedestal extractor fans: Pedestal or floor extractor fans are large free-standing fans mounted on a pedestal that can be adjusted to various heights depending on the desired height needed for airflow.
• Drum extractor fans: Also known as barrel extractor fans, drum extractor fans have a barrel-shaped housing with airflow directed horizontally along the floor. They are used for a wide range of applications, such as removing smoke from welding workshops, overhauling cooling systems in mining, and other industrial ventilation tasks.
• Tilting extractor fans: Tilting extractor fans come equipped with a tilting feature that allows users to adjust the direction of airflow by tilting the fan head up or down to suit different needs and cooling purposes.
• High-velocity extractor fans: High-velocity extractor fans usually have a smaller blade diameter that rotates at high speed. They are suitable for applications where there is a need for powerful extraction, such as warehouses, spray booths, and also providing ventilation in tunnels when mining.
