HVAC & Industrial Fans: Types, Applications & Selection Guide

01What are HVAC and industrial fans?

HVAC and industrial fans are used to move air through buildings, ducts, equipment and industrial ventilation systems. The correct fan selection depends on the required airflow, static pressure, temperature, installation arrangement and application.

Fan configurations can include axial fans, roof-mounted fans, tubular inline fans, ceiling-mounted fans, fresh-air fans, jet fans, tunnel ventilation fans, smoke extraction fans and high-temperature industrial fans.

• General ventilation and air movement
• Fresh-air supply
• Exhaust and extract ventilation
• Smoke extraction
• High-temperature ventilation
• Industrial and process ventilation

02Axial fans

Axial fans move air in a direction generally parallel to the fan shaft. They are widely used where high airflow and practical installation are required.

Axial fans can be supplied in different sizes and configurations for wall-mounted, duct-mounted, roof-mounted and industrial ventilation applications.

Depending on the application, configurations may include standard ventilation, high-temperature operation and smoke extraction.

Typical applications include:

• Industrial buildings
• Warehouses and factories
• Car parks
• Commercial buildings
• Oil and gas facilities
• Smoke extraction systems
• General ventilation systems

03Roof-mounted fans

Roof-mounted fans are installed on building roofs for exhaust, ventilation and air extraction applications. They can provide a practical solution where air needs to be discharged directly through the roof.

Depending on the project requirements, roof-mounted fan configurations can include axial or centrifugal arrangements, weather-resistant construction and high-temperature or smoke-extraction options.

Typical applications include factories, warehouses, commercial buildings, industrial facilities and process ventilation systems.

04Tubular inline fans

Tubular inline fans are designed for installation within ductwork where a compact fan arrangement is required.

They are commonly used for toilet extraction, general exhaust, fresh-air movement and ducted ventilation in commercial, residential and light industrial applications.

Selection should consider the required airflow, static pressure, duct size, installation position and operating environment.

05Ceiling and fresh-air fans

Ceiling-mounted and fresh-air ventilation fans are used to provide air movement, exhaust or fresh-air supply within buildings.

These systems can be selected according to room size, airflow requirement, installation arrangement and ventilation duty.

Typical applications include:

• Offices
• Commercial buildings
• Residential buildings
• Hotels
• Retail facilities
• Service areas
• General building ventilation

06Jet fans and tunnel ventilation fans

Jet fans are designed to move and control air within large enclosed spaces without requiring a conventional duct network throughout the entire area.

They are commonly used in car parks, tunnels and large enclosed ventilation systems where airflow direction and smoke movement are important design considerations.

Tunnel ventilation systems may use multiple fans arranged according to the required airflow pattern, pressure conditions and smoke-control strategy.

Fan selection should always follow the approved ventilation design and project requirements.

07Smoke extraction and high-temperature fans

Smoke extraction fans are designed for applications where smoke and hot gases need to be extracted during a fire condition.

High-temperature fan selection depends on the required temperature rating, operating duration, airflow, pressure and applicable project standard or certification.

Depending on the specified application, high-temperature fan solutions can be configured for smoke extraction and demanding industrial ventilation duties.

The required temperature rating and duration should always be confirmed against the project specification and applicable certification.

08How to select the right industrial fan

The correct fan should be selected based on the complete operating requirement rather than airflow alone.

The main selection parameters include:

Providing accurate airflow and pressure requirements allows the fan to be selected closer to its intended operating point and helps avoid unnecessary oversizing.

• Required airflow
• Static pressure
• Fan operating point
• Air temperature
• Smoke or high-temperature duty
• Installation arrangement
• Duct dimensions
• Electrical supply
• Noise requirements
• Duty and operating hours
• Environmental conditions
• Required certifications and project standards

09Industrial fan applications

HVAC and industrial fans are used across a wide range of commercial, industrial and infrastructure applications.

Typical applications include:

• Manufacturing facilities
• Warehouses and distribution centres
• Commercial buildings
• Car parks
• Tunnels
• Oil and gas facilities
• Process plants
• Industrial ventilation systems
• Smoke extraction systems
• Equipment and machinery ventilation
• Fresh-air and exhaust systems
