AIRCOL 150C OP Glass and Wall Type Axial Fan

What is an Axial Fan?

An axial fan is a type of fan that facilitates air flow along the axis of the fan, parallel to the shaft around which its blades rotate. Air enters and exits the fan in a straight line, as the blades draw air in and push it out in the same direction. This design generates airflow by creating a pressure difference, resulting in high airflow velocity, although the pressure generated is relatively low.

Axial fans are particularly suitable for ventilating small to medium-sized spaces such as bathrooms, kitchens, pantries, laundry rooms, garages, and workplaces. They are commonly designed for direct installation on windows and feature ultra-lightweight back shutters that open with airflow and close when the fan is turned off.

Features of Axial Fans

• Mechanical Shutters: Protect against dust, unpleasant odors, humidity, and other external elements when not in use.
• Aesthetic Design: The front appearance is visually appealing.
• Easy Installation: Can be mounted vertically on windows with ease.
• Dust Protection: The air outlet flap protects against dust, odors, and cold, preventing heat loss.
• Removable Filters: Filters exposed to dust are easily removable for cleaning.
• Maintenance-Free: Self-lubricating motor bearings ensure quiet and long-lasting operation.
• Class H Insulation: The motor is designed to meet Class H insulation standards.
• Compliance: Products are manufactured in accordance with standards such as EN 60335-2-80, Low Voltage Equipment (2006/95/EC), and Electromagnetic Compatibility (2004/108/EC).

Considerations for Selecting an Axial Fan

When selecting an axial fan, consider the following parameters:

1. Required Airflow Rate: The amount of air needed for adequate ventilation.
2. Pressure Losses: Evaluate the loss of pressure in the ductwork.
3. Acceptable Noise Level: Determine the noise levels that are acceptable for the environment.
4. Electrical Power Connection Type: Choose between single-phase or three-phase electricity based on the application.
   
   

Calculating Required Airflow Rate

To determine the necessary airflow rate (Q), you can use the following formulas:

• Based on Air Exchange Rate:

  $$Q \, [m^3/h] = \text{Air exchange rate} \, (1 \, \text{hour}) \times \text{Room volume} \, (m^3)$$

• Based on Occupancy:

  $$Q \, [m^3/h] = \text{Number of people} \times \text{Required airflow rate per person}$$

For example, in an office with 5 people, a ceiling height of 2.6 meters, and a floor area of 50 m²:

1. Calculate the room volume:

   $$2.6 \, m \times 50 \, m^2 = 130 \, m^3$$

2. Using an air exchange rate of 5 (for offices), the airflow requirement is:

   $$130 \times 5 = 650 \, m^3/h$$

3. If each person requires 29 m³ of air:

   $$5 \times 29 = 145 \, m^3$$Total airflow requirement:
4. $$650 + 145 = 795 \, m^3/h$$

Installation Considerations

After determining the airflow requirements, consider where the fan will be installed—on the ceiling, wall, chimney, or ventilation pipe. Also, ensure that the electrical connection matches the fan's requirements; for residential applications, a single-phase fan is appropriate, while a three-phase fan (380 Volt) is suitable for industrial use.
