Aircol 200 K Covered Axial Fan / Aspirator 520 m³/h

What is an Axial Fan?

An axial fan is a type of fan that causes air to flow in an axial direction, meaning parallel to the shaft on which the blades rotate. Both the inlet and outlet airflow are axial. The blades rotate around an axis, pulling air in parallel to this axis and pushing it out in the same direction. The fan is designed to generate force by creating a pressure difference, resulting in airflow through the fan.

Axial fans produce a high airflow rate, enabling the movement of large volumes of air. However, they generate low pressure in the airflow.

Applications

For Small and Medium-Sized Spaces

• Suitable for ventilation in areas like bathrooms, toilets, kitchens, pantries, laundry rooms, garages, and workplaces.
• Designed for direct mounting onto windows.

For Large and Medium-Sized Spaces

• Ideal for ventilating kitchens, bathrooms, offices, pantries, and garages.
• Specifically produced for direct connection without the use of ducts to expel dirty and polluted air from the interior.

Features

• Aesthetic rear louver ensures protection against dust, bad odors, humidity, cold, and other external factors when the aspirator is not in use.
• Cord-operated rear cover stops automatically when closed and operates when opened.
• Easy cleaning: The dust-exposed front cover, body, and fan blades can be wiped clean.
• Optimized motor and body design minimizes noise levels.
• Self-lubricating motor bearings ensure quiet and long-lasting performance.
• Easy window mounting capability.
• Water resistance: Equipped with IPX4 protection against water splashes.

Usage Options

• Manual adjustment using a pull-cord cover that functions as an on/off switch.
• Time-delay electronic control: The fan can continue operating for a set duration after being turned off.
• Thermal protection: Prevents motor wear in high-temperature environments.

Axial Fan Selection Criteria

When selecting an axial fan, consider four key parameters:

1. Required Airflow (m³/h)
2. Pressure Losses
3. Acceptable Noise Levels
4. Electrical Power Connection Type

The required ventilation capacity for a space depends on its purpose, number of occupants, and activities performed within it. The table below outlines the necessary air exchange rates for different environments:

Required Airflow Calculation:

1. Using Air Exchange Rate

   $$Q \, [m^3/h] = \text{Air Exchange Rate (per hour)} \times \text{Room Volume (m³)}$$

2. Using Number of People

   $$Q \, [m^3/h] = \text{Number of People} \times \text{Required Airflow per Person (m³/h)}$$

Example Calculation

Consider an office where:

• 5 people work
• Ceiling height = 2.6m, floor area = 50m²
• Room Volume = $2.6 \times 50 = 130 m³$
• Air Exchange Rate for an Office = 5 (average value from the table)
• Total Required Airflow = $130 \times 5 = 650 m³/h$
• Additional Requirement for Occupants (assuming normal activity) = $5 \times 29 = 145 m³/h$
• Total Airflow Requirement = 650 + 145 = 795 m³/h

Fan Installation Considerations

Once airflow requirements are determined, consider:

• Installation location (ceiling, wall, duct, chimney, etc.).
• Electrical connection (Voltage requirements).
  • For residential use: Choose a single-phase (220V) fan.
  • For industrial settings: Use a three-phase (380V) fan.

By considering these factors, you can select the right axial fan to ensure effective ventilation.
