Industrial fans and elements of ventilation systems are in demand at enterprises in various industries, in the service sector, and shopping malls. General ventilation is divided into two types — supply ventilation, which provides an influx of fresh air into the room, and exhaust ventilation, which is responsible for removing exhaust air to the outside. The performance of industrial exhaust and supply fans serving the facility must ensure balanced pressure in the internal space.
Types of industrial fans
Ventilation equipment is available in a wide range of designs:
- Radial (centrifugal) industrial fans, often called «scroll» fans. Designed to move gas-air flows that do not contain solid mechanical particles. Used in supply and exhaust and fire protection systems. A distinctive design feature is the presence of a wheel with radially arranged blades. The rotation of the wheel creates a centrifugal force, due to which an industrial fan sucks in or transmits an air stream in a given direction.
- Axial. They are mainly used in large industrial premises. They consist of a round body with an axis on which an impeller with air intake blades is located. Axial models move significant volumes of air at low pressure. Advantages: high efficiency and reduced noise level. Industrial axial exhaust fans are equipment often used in fire extinguishing systems.
- Roof. They are installed on the roof, which saves interior space. By design, roof models can be axial or radial.
- Duct. Compact models are installed in ventilation ducts of round or rectangular cross-section. The larger the duct cross-section, the more powerful the duct fan should be.
The housings of industrial units can be heat-resistant, explosion-proof, or corrosion-resistant. Soundproofed models provide reduced noise levels. Fans can be designed for use only in an exhaust or supply system, and there are also universal supply and exhaust models.
Selection criteria for industrial fans
Before selecting suitable ventilation equipment, it is necessary to determine:
- composition of the transported environment, planned concentration of pollutants, their nature;
- volume of serviced premises;
- possible installation options;
- total pressure value.
Calculations carried out before purchase allow you to select a fan that fully corresponds to the planned operating conditions and functional purpose. Important characteristics of ventilation equipment:
- power consumption;
- performance;
- noise level;
- permissible installation locations;
- environments with which the unit can work;
- housing resistance to aggressive environments.
What technical problems do industrial fans solve?
The use of powerful ventilation equipment allows you to:
- create optimal conditions for the functioning of refrigeration, heating and drying equipment;
- remove intense odors, for example in paint shops;
- create the effect of strong wind in theatrical productions and when shooting video materials;
- quickly remove smoke and excess heat from the room.
