Product description

What Is a Radial Fan?

Fans that generate a pressure difference are called radial fans. The resulting air effect acts in the direction of centrifugal force. A centrifugal fan is a mechanical device used to move air or other gases. Like a pump, these fans have a rotating impeller and a spiral-shaped housing in which the impeller sits. Air or gas enters axially through the center, is pressurized and discharged tangentially from the impeller periphery into ducts, and is expelled through the outlet. Due to the high pressure they generate, centrifugal fans are ideal for high-pressure applications such as drying and air conditioning systems. Since all moving parts are enclosed, they also have particle-reducing properties that make them ideal for use in air pollution control and filtration systems.

Aircol 250F – Applications

For small and medium-sized spaces:
Suitable for ventilating bathrooms, toilets, kitchens, pantries, laundry rooms, garages, workplaces, and similar spaces.
It is manufactured specifically for ceiling ventilation applications, to be used together with a duct connection pipe attached to the extractor.

Aircol 250F Ceiling Exhaust Fan – Features

It is an indispensable choice for spaces where a stylish and wide front appearance is desired to create a striking impression.
Manufactured from high-quality ABS plastic, our product provides the best protection against bad odors, moisture, and similar external factors while never losing its original appearance.
With its wide air sweep path body and optimum fan design, noise levels have been reduced to a minimum.
The specially designed body and front cover provide high suction from all directions while keeping the front cover clean at all times.
We can manufacture our exhaust fan at the desired flow rate and speed to suit the application environment. (120 m³/h ~ 150 m³/h)
The air outlet flap provides the best protection against dust, odors, and cold that could enter from outside when the fan is not in use, while also preventing heat loss from inside to outside.
It can be made dual-speed upon request.
The dust-exposed filter can be removed very easily and cleaned by wiping or washing.
Self-lubricating, maintenance-free motor bearings provide quiet and long-lasting performance.
It has IP24 protection against water splashing.
The motor is in insulation Class H.
Our products are manufactured in accordance with EN 60335-2-80, Low Voltage Equipment [2006/95/EC] and Electromagnetic Compatibility [2004/108/EC] standards.

Aircol Fan Installation

Things to Consider When Selecting an Axial 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 Coefficient
Classrooms	5-7
Libraries	4-5
Domestic kitchens	15-25
Bathrooms	5-7
Domestic restrooms	4-5
Public restrooms	8-15
Conference rooms	6-8
Offices	4-8
Changing rooms	6-8

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.
