What Is a Circulation Fan?

Fans used to provide air circulation in enclosed spaces are called circulation fans. These fans are designed to move the maximum amount of air with minimal noise and energy consumption. Circulation fans also cool warm environments and offer a low-cost solution in greenhouses, factory production areas, barns, and similar locations. Circulation fans provide uniform temperature distribution in greenhouses, livestock barns, poultry houses, or commercial warehouses. These versatile and durable fans, designed for high airflow and high efficiency, are an ideal cooling solution for industrial or commercial facilities. They are next-generation, highly energy-efficient, robust, and reliable air-blowing fans suitable for a wide range of professional indoor climate applications.

Fan Housing and Impeller

Casing and fan blades made of cold-drawn, high-quality DKP sheet steel,
Environmentally friendly electrostatic epoxy powder coating for corrosion resistance,
High-resistance fan blades dynamically balanced in accordance with ISO 1940 standards,
Rear protective guard compliant with EN 60335-2-80 standards,

Motor

Quality production without manual handling on high-technology CNC machines,
Aluminum-finned motor casing with high thermal conductivity,
Rotor balanced to ISO 1940 standards for extended bearing service life,
Class F insulation for windings, providing a wide operating range of –40°C to +70°C,

Applications

In areas requiring air circulation,
Greenhouses,
General and industrial buildings,
Warehouses, stockrooms, and storage facilities,
Garages and publicly accessible buildings, agricultural buildings,
Large workshops,
Paint shops,
Factories,
Environments with dust and vapor,
Poultry farms,
Barns,
Used for cooling industrial marinas.

Points to Consider When Selecting a Fan

4 parameters should be considered when selecting a fan:

Required Air Flow Rate
Pressure Losses
Acceptable Noise Level
Electrical Power Connection Type

The air changes required for the space to be ventilated depend on the intended use of the space, the number of occupants and objects inside, and their activities. The table alongside provides the required air change rate coefficients for different environments.

Environment	Air Change Rate
Auditoriums	6-8
Paint Ovens	25-50
Vault Rooms	3-6
Cinemas and Theaters	5-8
Commercial Kitchens	15-30
Foundries	8-15
Gymnasiums	4-6
Laundries	10-20
Indoor Swimming Pools	3-4
Restaurants	8-12
Conference Rooms	6-8
Waiting Rooms	Copy Rooms
Copy Rooms	10-15
Machine Rooms	10-40
Shops	4-8
Dry Cleaning	5-15
General Manufacturing Areas	4-8
Hospitals	8-12
Laboratories	8-15
Normal Activity (non-smoking)	29 m³/h
Normal Activity (smoking)	58 m³/h
Light Activity	45 m³/h
Heavy Activity (industrial work areas)	60 m³/h

The amount of air per person in living and working spaces depending on activity level can help determine the required air flow rate.

Normal Activity (Non-Smoking)	29 m³/h
Normal Activity (Smoking)	58 m³/h
Light Activity	45 m³/h
Heavy Activity	60 m³/h

Based on the information provided above, the required air flow rate is determined as follows.

Q [ m³/h ] = Air change rate coefficient (1 hour) × Space volume (m³)

Q [ m³/h ] = Number of people × Air flow rate required per person

After determining the required air flow rate for the space, an appropriate duct design (taking noise and air velocity criteria into account) should be made and pressure losses calculated. The fan type (axial, radial, roof, smoke extraction, etc.) should be decided based on the operating environment, and the appropriate fan should be selected from the relevant fan curve according to the determined flow rate–static pressure pair. To briefly illustrate the above with an example: an office has 5 employees, a ceiling height of 2.6 meters, and a floor area of 50 m², giving a volume of 2.6 × 50 = 130 m³. The air change rate coefficient given for an office in the table is 4–8; let's take 5. 130 × 5 = 650 m³/h air requirement. If we assume normal activity in the office, 5 people × 29 m³ = 145 m³ for employees, giving a total of 650 + 145 = 795 m³/h air requirement.

Fan selection is also made based on this flow rate requirement.

After completing the flow rate calculations, the installation location of the fan should be determined. Where will the fan be mounted — ceiling, wall, chimney, or ventilation duct? Another consideration is the voltage of the electrical supply to the fan. Continuing with our office example: fans in offices are generally mounted on a wall or glass. If a domestic electricity supply is used, a single-phase fan should be preferred. If it is to be used in an industrial setting, a fan operating on three-phase (380 V) power should be used.
