Aircol 100 Automatic Shutter Toilet and Bathroom Fan / Aspirator 100 m³/h - Aircol 100 OP

What is a Radial Fan?

Radial fans are fans that create a pressure difference. The air movement occurs in the direction of the centrifugal force. A centrifugal fan is a mechanical device used to move air or other gases. These fans have a rotating wheel, similar to a pump, and a helical casing in which the wheel operates. Air or gas enters parallel to the axis, is pressurized, and is directed tangentially to the wheel to be transferred to the ducts and expelled through the outlet.

Due to the high pressure they generate, centrifugal fans are ideal for applications that require high pressure, such as drying and air conditioning systems. Because all moving parts are enclosed and they also have features that reduce particles, they are ideal for use in air pollution and filtration systems.

Applications

In small and medium-sized spaces: Suitable for ventilation of places such as bathrooms, toilets, kitchens, pantries, laundry rooms, garages, workplaces, etc. These fans are specifically designed for use with direct connection or ducts up to 3 meters.

Features

• The automatic louver opens 30 seconds after the fan starts and closes 30 seconds after the fan stops.
• The automatic louver provides the best protection against dust, bad odors, and cold air from outside when the fan is off.
• The internal louver design prioritizes the aesthetic appearance of the front cover, rather than the louvers.
• Manufactured from high-quality ABS plastic, the fan offers excellent protection against bad odors, humidity, and other external factors, while maintaining its original appearance.
• The front cover can be easily cleaned by wiping it.
• The optimal motor and body design minimize the noise level.
• Self-lubricating motor bearings provide silent and long-lasting performance.
• The fan can be easily mounted on walls, ceilings, windows, etc., either vertically or horizontally.
• The included locking clamp makes installation easy.
• Our products are manufactured in compliance with EN 60335-2-80, Low Voltage Equipment - 2006/95/EC, and Electromagnetic Compatibility - 2004/108/EC standards.

Radial Fan Selection Considerations

When selecting a fan, four parameters should be considered:

• Required airflow
• Pressure losses
• Acceptable noise level
• Electrical power connection type

The required air change for the ventilation of a space depends on the space's usage, the number and activities of people and items inside. The table below shows the required air change rates for various environments.

The required airflow for a space can be determined using the following formulas:

• Q[m3/hour]=Air Change Rate (1 hour)×Space Volume (m³)
  
  Q [m³/hour] = \text{Air Change Rate (1 hour)} \times \text{Space Volume (m³)}
  Q[m3/hour]=Air Change Rate (1 hour)×Space Volume (m³)
• Or,
• Q[m3/hour]=Number of People×Required Airflow per Person
  
  Q [m³/hour] = \text{Number of People} \times \text{Required Airflow per Person}
  Q[m3/hour]=Number of People×Required Airflow per Person

After determining the required airflow, an appropriate duct design (considering sound and air speed criteria) should be made, and pressure losses should be calculated. Based on the environment, the type of fan (axial, radial, roof, smoke extraction, etc.) should be chosen, and the fan curve should be selected based on the required airflow and static pressure.

For example, let's calculate the airflow for an office with 5 people, a ceiling height of 2.6 meters, and a floor area of 50 m². The volume of the room is

2.6×50=130 m3 2.6 \times 50 = 130 \, m³

2.6×50=130m3. According to the air change rate table, for an office, the value is 4-8. Taking 5 as the average, the airflow required is

130×5=650

m3/h

130 \times 5 = 650 \, m³/h

130×5=650m3/h. Additionally, for normal activity (non-smokers), the airflow requirement for each person is

5×29=145 m3
5\times 29 = 145 \, m³

5×29=145m3, so the total airflow required is

650+145=795 m3/h

650 + 145 = 795 \, m³/h

650+145=795m3/h. Based on this calculation, the fan should be selected to meet this airflow requirement.

Once the airflow calculation is done, the location for the fan installation should be determined. Where will the fan be installed? On the ceiling, wall, chimney, or ventilation duct? Another consideration is the voltage of the electrical connection. In office settings, fans are typically mounted on the wall or window. For residential use, a single-phase fan should be preferred, while for industrial areas, a three-phase (380V) fan should be used.
