High Temperature Fans

High-temperature fans are specialised ventilation devices designed to operate reliably in environments that exceed normal thermal conditions. Constructed from heat-resistant materials, they provide durable and safe airflow solutions for industries such as manufacturing, foundries, power generation, and chemical processing. In the UK, high-temperature fans must be specified in line with Building Regulations Part F (Ventilation), Part L (Conservation of Fuel and Power), and where applicable, Approved Document B (Fire Safety). They may also need to comply with standards such as BS EN 12101-3 (smoke and heat control), BS EN 14986 (ATEX for hazardous environments), and BS 7671 (electrical safety).

Frequently Asked Questions

How do High Temperature Fans Work?

High-temperature fans use durable motors and heat-resistant blades to deliver steady airflow at elevated temperatures.
Unlike standard fans, they maintain continuous performance where extreme heat is present. These fans are often certified for operation at specific temperature/time ratings (e.g. 300°C for 2 hours) in line with BS EN 12101-3 for smoke and heat control systems.

Benefits of High Temperature Fans

✔ Durability Under Extreme Conditions – Built to withstand environments such as factories, foundries, and kilns.

✔ Reliable Performance – Continuous operation ensures safe temperature control in demanding applications.

✔ Energy Efficiency – Many models meet UK Ecodesign regulations, reducing operating costs.

✔ Reduced Maintenance – Strong construction minimises servicing needs, lowering lifetime costs.

✔ Versatile Applications – Effective for cooling, exhaust, and process ventilation across multiple sectors.

Applications of High Temperature Fans

• Industrial Manufacturing – Used in metal forging, glass production, and chemical processing.

• Casting – Provides cooling and ventilation in high-heat casting environments.

• Boiler Rooms – Handles hot gas emissions, protecting workers and equipment.

• Power Plants – Maintains safe turbine and machinery operation by cooling critical systems.

• Ovens & Kilns – Distributes heat evenly for curing, drying, or baking processes.

• Smoke & Heat Control – Certified fans operate at extreme temperatures during fire emergencies (BS EN 12101-3).

Choosing the Right High Temperature Fan

When selecting a high-temperature fan, consider the following factors:

• Maximum Operating Temperature – Ensure certification for the required conditions (e.g.300°C/2hr).

• Airflow Requirements – Calculate airflow in m³/h or l/s to match cooling/ventilation needs.

• Installation Space – Confirm dimensions and compatibility with ductwork or exhaust systems.

• Noise Levels – For noise-sensitive environments, check compliance with BS 8233:2014 indoor noise guidelines.

• Energy Efficiency – Select models compliant with UK Ecodesign regulations and UKCA marking.

• Environment – For hazardous or explosive zones, specify ATEX-rated fans in line with BS EN 14986.

• Electrical Compliance – Ensure installation meets BS 7671 (IET Wiring Regulations).

Maintenance Tips for High Temperature Fans

• Inspect regularly for wear, damage, or heat stress in high-temperature areas.

• Clean blades and housings to prevent dust and debris build-up that may impair airflow.

• Lubricate bearings and moving parts in line with manufacturer guidance.

• Monitor fan performance and noise levels to identify early signs of faults.

• For LEV applications (COSHH), test and inspect at least every 14 months as per HSE requirements.
