POPULA

A reliable fire smoke exhaust fan solution is an important part of smoke control and emergency ventilation design for commercial buildings, underground parking areas, high-rise projects, and public facilities. In this project case, POPULA supported a commercial building ventilation project with fire smoke exhaust fans, cabinet centrifugal fans, axial smoke exhaust fans, and pressurization ventilation equipment.

The goal of the project was to provide a practical fan selection plan for smoke exhaust, air movement, and emergency ventilation areas. The system needed to match duct resistance, installation space, airflow requirements, and building safety design conditions.

Project Background

The project was a commercial building development with underground parking areas, equipment rooms, public corridors, and service zones. Because the building included enclosed spaces and ducted ventilation routes, the smoke exhaust system required fans with stable airflow and suitable pressure performance.

The customer needed a fan supplier that could provide multiple product types for different smoke control areas. Instead of using only one general fan model, the project required a combination of equipment for smoke exhaust, ducted ventilation, and pressurization air supply.

Customer Requirements

Before product selection, the customer provided basic project information including airflow requirements, duct layout, installation position, power supply, and application area. The main requirement was to select fans that could support emergency ventilation and smoke exhaust functions in different parts of the building.

Main Requirements

Site Conditions and Selection Challenges

Commercial building projects often include long duct runs, elbows, dampers, silencers, and limited equipment room space. These factors can increase system resistance and make fan selection more complex.

For underground parking areas, the ventilation system may need to support both daily exhaust and emergency smoke exhaust requirements according to the project design. For stairwell or corridor areas, positive pressure air supply may also be considered to help maintain protected evacuation routes.

Because of these different working conditions, POPULA recommended selecting fan models according to the function of each system section instead of applying one fan type to the whole project.

POPULA Fire Smoke Exhaust Fan Solution

The final fire smoke exhaust fan solution combined several types of industrial ventilation equipment. Each fan type was selected based on airflow, pressure, installation method, and application zone.

1. HTF Fire Smoke Exhaust Fans

HTF fire smoke exhaust fans were recommended for major smoke exhaust sections where high airflow and reliable emergency ventilation performance were required. These fans are commonly used in commercial buildings, underground parking areas, tunnels, and other smoke control projects.

For this project, HTF fire smoke exhaust fans were considered for main exhaust routes connected to smoke exhaust ducts and outlet shafts.

2. Axial Smoke Exhaust Fans

Axial smoke exhaust fans were selected for areas requiring large airflow and relatively direct air discharge. Their compact structure makes them suitable for certain duct sections, wall openings, or equipment zones where space is limited.

In commercial building projects, axial smoke exhaust fans can help move large air volumes efficiently when the system resistance is suitable for axial fan operation.

3. Cabinet Centrifugal Fans

Cabinet centrifugal fans were used for ducted ventilation areas where stable pressure was needed. Compared with axial fans, centrifugal fans can handle higher duct resistance and are suitable for mechanical ventilation rooms, HVAC exhaust, and pressurization air supply systems.

The cabinet design also supports cleaner installation in commercial building equipment rooms and can help reduce exposed moving parts in service areas.

4. Pressurization Ventilation Support

Positive pressure air supply is often used in stairwells, antechambers, or protected evacuation areas depending on the building design. For this type of application, fan selection must consider airflow volume, pressure, duct resistance, and control requirements.

POPULA can recommend suitable fan models according to the pressurization system design and installation conditions.

Installation Considerations

For fire smoke exhaust and emergency ventilation projects, installation planning is just as important as product selection. Fan location, duct connection, vibration control, maintenance space, electrical access, and air outlet design can all affect system performance.

Key Installation Points

Project Results

By combining different fan types, the project achieved a more practical smoke exhaust and emergency ventilation layout. Main exhaust areas were supported by fire smoke exhaust fans, ducted sections were supported by centrifugal fans, and high-airflow areas could use axial smoke exhaust fans where suitable.

The customer received a fan selection plan that matched different building zones instead of relying on a single product type. This made the overall fire smoke exhaust fan solution more adaptable to the commercial building layout.

Solution Benefits

Why Fan Selection Matters in Smoke Exhaust Projects

Smoke exhaust fan selection should not be based only on fan diameter or motor power. A suitable fan must match the required airflow, pressure, working temperature, duct layout, and installation environment.

In commercial buildings, ducts and dampers may create significant system resistance. If the fan pressure is too low, the exhaust performance may not meet the intended design. If the fan is oversized, the system may face unnecessary noise, cost, and energy consumption.

That is why POPULA recommends reviewing project data before final fan selection.

A reliable factory ventilation solution is essential for manufacturing workshops in Southeast Asia, where high temperatures, humidity, heat-generating equipment, and long production hours can make indoor air quality difficult to control. In this project case, POPULA provided an industrial ventilation plan combining axial fans, centrifugal fans, and fresh air supply to improve airflow inside a manufacturing workshop.

The project focused on removing accumulated heat, improving air exchange, and supporting a safer and more comfortable production environment. Instead of using only one fan type, the solution matched different ventilation equipment to different areas of the workshop.

Project Background

The customer operated a medium-sized manufacturing workshop in Southeast Asia. The building had a metal roof, several heat-producing machines, and limited natural ventilation. During the hot season, indoor temperatures increased quickly, especially in production zones far from doors and windows.

The customer needed a practical factory ventilation solution that could improve air movement without interrupting daily production. The system also needed to be easy to maintain, suitable for continuous operation, and flexible enough for future workshop expansion.

Customer Challenges

Before the project upgrade, the workshop faced several common ventilation problems. Hot air gathered near the roof, production areas had uneven airflow, and some corners had poor air circulation. Workers also reported that the indoor environment became uncomfortable during peak afternoon temperatures.

Main Problems on Site

These conditions required more than simple wall exhaust. The system needed both general air exchange and targeted exhaust for specific working areas.

Site Conditions and Ventilation Requirements

The workshop layout included open production lines, storage areas, equipment zones, and loading access. Because the roof height was relatively high, hot air naturally moved upward and stayed near the upper area of the building. At the same time, some machines generated additional heat during continuous operation.

After reviewing the working conditions, POPULA engineers recommended a combined ventilation design. The main goal was to create a stable airflow path: bring in fresh air, guide air across the production area, remove hot air from upper zones, and extract local heat where necessary.

POPULA Factory Ventilation Solution

The final factory ventilation solution used a combination of axial fans, centrifugal fans, and fresh air components. Each product type played a different role in the system.

1. Axial Fans for General Workshop Exhaust

Wall-mounted axial fans were selected for large-volume air exchange. These fans were installed along the side walls to exhaust hot indoor air and support continuous airflow across the workshop.

Axial fans were suitable because the workshop required high airflow with relatively low resistance. Their compact structure also made installation easier, especially in areas where long ducts were not practical.

2. Centrifugal Fans for Local Exhaust Areas

For equipment zones with higher exhaust resistance, centrifugal fans were used to provide stronger pressure. These fans helped extract hot air from selected process areas and move it through ductwork to the outside.

Centrifugal fans were recommended because they can handle duct resistance, elbows, and local exhaust points more effectively than general axial fans.

3. Fresh Air Supply for Better Air Replacement

Exhaust alone is not enough for a balanced ventilation system. Fresh air supply points were arranged to help replace discharged air and reduce negative pressure inside the workshop.

By combining exhaust fans with fresh air intake, the workshop could maintain more stable airflow and avoid pulling unfiltered air from uncontrolled openings.

Installation Method

The installation was planned to reduce disruption to the customer’s production schedule. Wall-mounted axial fans were positioned in areas where hot air could be discharged directly. Centrifugal fans were connected to duct sections for local exhaust points near heat-generating equipment.

Fresh air openings were arranged according to airflow direction, production layout, and building structure. This helped create a clear ventilation path from fresh air intake to exhaust outlet.

Key Installation Considerations

Project Results

After installation, the workshop achieved better air movement and more stable ventilation. Hot air was removed more effectively, and the production area had improved air exchange. The customer also reported a more comfortable working environment during hot weather.

The combined system provided a practical balance between performance, installation cost, and maintainability. Instead of relying on one large fan type, the solution used different equipment where each fan performed best.

Observed Improvements

Why a Combined Fan System Works Better

Many factory ventilation projects need more than one type of fan. Axial fans are excellent for large airflow and direct exhaust, while centrifugal fans are better for ducted exhaust and higher resistance areas. Fresh air supply helps make the whole system more balanced.

In this Southeast Asia workshop project, the combined system allowed each ventilation product to work in the right position. This made the factory ventilation solution more efficient and easier to manage in daily operation.

When planning an industrial ventilation system, one of the most common questions is: axial fan vs centrifugal fan — which one should I choose? Both fan types are widely used in factories, warehouses, commercial buildings, HVAC systems, smoke exhaust systems, and process ventilation. As an industrial fan manufacturer, POPULA helps customers compare fan types according to real airflow conditions, system pressure, and installation requirements.

Choosing the wrong fan may lead to insufficient airflow, excessive noise, high energy consumption, poor exhaust performance, or unstable system pressure. This guide explains the main differences between axial fans and centrifugal fans, helping you make a better selection for your industrial ventilation project.

What Is an Axial Fan?

An axial fan moves air in a straight direction along the fan axis. The airflow enters and exits the fan in the same line, similar to how a propeller works. Axial fans are commonly used when a large volume of air needs to be moved with relatively low pressure resistance.

In industrial applications, axial fans are often installed on walls, roofs, ducts, production workshops, warehouses, greenhouses, underground parking areas, and general ventilation systems. They are suitable for direct exhaust, fresh air supply, heat removal, and air circulation.

Typical Features of Axial Fans

What Is a Centrifugal Fan?

A centrifugal fan changes the direction of airflow. Air enters the fan wheel near the center and is discharged outward by centrifugal force. Compared with axial fans, centrifugal fans can generate higher pressure, making them suitable for ducted systems and applications with higher resistance.

Centrifugal fans are often used in HVAC systems, dust collection, fume extraction, filtration systems, air handling units, kitchen exhaust systems, boiler ventilation, and industrial process exhaust. They are especially useful when air must pass through long ducts, filters, silencers, dampers, or elbows.

Typical Features of Centrifugal Fans

Axial Fan vs Centrifugal Fan: Key Differences

The main difference between an axial fan and a centrifugal fan is how they move air and how much pressure they can provide. Axial fans are usually selected for high airflow and low pressure. Centrifugal fans are selected for higher pressure and higher system resistance.

1. Airflow Direction

An axial fan moves air straight through the fan. This makes it suitable for wall-mounted exhaust, roof ventilation, tunnel ventilation, and open-space air circulation.

A centrifugal fan changes airflow direction inside the fan housing. This structure allows the fan to build higher pressure, which is useful for duct systems and equipment ventilation.

2. Air Volume and Pressure

Axial fans are strong in air volume. If your project requires moving a large amount of air across a short distance, an axial fan is often the practical choice.

Centrifugal fans are stronger in pressure. If your system includes long ducts, filters, bends, dampers, or other resistance, a centrifugal fan is usually more suitable.

3. Installation Conditions

Axial fans are often easier to install because of their compact design. They can be mounted on walls, windows, ducts, roofs, or ventilation openings.

Centrifugal fans usually require more installation space because of the fan casing, outlet direction, base frame, and duct connection. However, they provide better performance in more complex ventilation systems.

4. Noise and Efficiency

Noise level depends on fan speed, blade design, airflow volume, pressure, and installation conditions. In general, axial fans can be efficient for low-resistance ventilation, while centrifugal fans can be more efficient in high-resistance duct systems.

For both fan types, correct selection is more important than simply comparing the product type. A properly selected fan can reduce noise, improve airflow stability, and lower operating costs.

When Should You Choose an Axial Fan?

You should consider an axial fan when your ventilation system requires large airflow with low pressure resistance. This is common in general factory ventilation, workshop cooling, warehouse exhaust, fresh air supply, and direct wall or roof ventilation.

Axial fans are also a good choice when the installation space is limited and the air path is relatively simple. For example, if hot air needs to be exhausted directly from a production workshop to the outside, an axial fan can be an efficient and economical solution.

Common Applications of Axial Fans

When Should You Choose a Centrifugal Fan?

You should consider a centrifugal fan when the system has higher resistance or requires stable pressure. This often happens when air must move through ducts, filters, dust collectors, silencers, dampers, or multiple elbows.

Centrifugal fans are also commonly used for industrial exhaust systems where the air contains dust, fumes, heat, or process gases. Different impeller types and materials can be selected according to the working condition.

Common Applications of Centrifugal Fans

How to Select the Right Industrial Ventilation Fan

Before choosing between an axial fan and a centrifugal fan, it is important to understand the actual working conditions. A fan should not be selected only by motor power or fan diameter. The correct selection depends on airflow, pressure, medium, temperature, installation method, noise requirements, and system resistance.

Key Information Needed for Fan Selection

If these conditions are not clear, POPULA engineers can help review the project requirements and recommend a suitable fan model. Providing airflow, pressure, layout drawings, and working environment information will make the selection more accurate.

Axial Fan vs Centrifugal Fan: Quick Selection Summary

For simple ventilation with large airflow and low resistance, an axial fan is often the better choice. For ducted systems, filtration systems, dust extraction, or higher pressure requirements, a centrifugal fan is usually more suitable.

In many industrial projects, axial fans and centrifugal fans can also be used together. For example, axial fans may provide general workshop ventilation, while centrifugal fans handle local exhaust, dust collection, or process ventilation.

FAQ

Which is better, axial fan or centrifugal fan?

Neither is always better. An axial fan is better for large airflow and low resistance ventilation, while a centrifugal fan is better for higher pressure and ducted systems.

Can axial fans be used with ducts?

Yes, axial fans can be used with short and low-resistance ducts. For long ducts or systems with filters and many elbows, a centrifugal fan is usually more suitable.

Why do centrifugal fans provide higher pressure?

Centrifugal fans use an impeller and casing design that changes airflow direction and generates higher static pressure, making them suitable for systems with higher resistance.

What information is needed before selecting an industrial fan?

The most important information includes airflow, pressure, duct layout, air temperature, working environment, installation method, voltage, and noise requirements.
