Extraction Fans (Industrial & Domestic) in South Africa

Ensure clean, ventilated, safe environments with the right extraction fan. Whether for a domestic bathroom, commercial kitchen or industrial workspace, this guide helps you select, install and maintain extraction and exhaust fans suited for South Africa’s conditions.

What Are Extraction Fans?

Extraction (or exhaust) fans are ventilation devices that remove stale air, moisture, fumes, odours or heat from a space and expel them outdoors. They help maintain air quality, prevent mould growth, reduce odours, and create safer working environments.

Where & Why They Are Used

• Domestic Bathrooms & Toilets – remove excess moisture to prevent mould and dampness, improve comfort.
• Kitchens (Residential & Commercial) – remove cooking odours, heat, grease vapours; commercial kitchens often required by law to have proper extraction.
• Workshops & Mechanical / Automotive Spaces – extract fumes, dust, harmful gases for worker health and safety.
• Industrial Facilities & Factories – regulate temperature, moisture, airborne pollutants; maintain safe environment.
• Smoke Control in Buildings – smoke extractor fans to comply with building safety codes (for example SANS standards) in public buildings, multi-storey structures.

Key Specifications to Consider

Selecting the right extraction fan involves several technical and practical parameters. Here’s what to compare:

• Airflow Capacity (m³/h or CFM) – how much air the fan can move. Match to room size, kitchen load, number of baffles, length of ducting and bends.
• Static Pressure & Duct Length – higher static pressures needed for longer or complex duct runs; bends and restrictions lower performance.
• Fan Type – axial, centrifugal, wall-mounted, roof-mounted, shutter fans. Each suited to different use cases.
• Noise Level (dB) – especially important in domestic spaces, guesthouses, or offices; quieter fans are more comfortable.
• Material & Build Quality – metals vs plastics; corrosion resistance (important in coastal areas or kitchens); non-combustible materials in cooking environments.
• Power Type & Efficiency – electric motors; EC-motors (electronically commutated) offer better efficiency; look for energy usage ratings. Also check whether fan draws high power under load or peak conditions.
• Shutters, Dampers & Controls – features like backdraft shutters, humidity or temperature controllers, timer switches help automation and prevent energy loss.
• Compliance with Local Regulations – building codes (SANS 10400-T), health and safety requirements for kitchens and smoke extraction systems.

Domestic vs Industrial Extraction Fan Differences

Understanding the difference helps you avoid overpaying or choosing a fan that fails to perform:

• Usage Frequency & Load – industrial units run many hours under load, need durable components; domestic units used less intensively.
• Durability & Maintenance – industrial fans designed for frequent cleaning and harsher environments; bearings, motors and coatings built for heavy duty.
• Size & Air Movement – industrial fan sizes much larger; airflow capacity much higher than domestic exhausts.
• Control Features – industrial units often include remote monitoring, safety cutouts, smoke detection integration; domestic typically simpler (on/off or timer or humidity sensor).

Regulations & Safety in South Africa

• Extractor fans in kitchens must meet SANS 10400 requirements for ventilation. Kitchens using gas appliances require non-combustible extractor units. 
• Smoke extraction systems in commercial buildings must comply with SANS 10400-T or relevant fire safety codes.
• Regular maintenance is essential - for both domestic and industrial fans - to ensure filters, shutters or grilles are clean, motor bearings lubricated, and airflow unobstructed. 

Tips for Choosing the Right Extraction Fan

• Measure the size of the space and determine required air changes per hour to estimate airflow needed.
• Account for duct length, bends, and potential obstructions - they reduce actual airflow.
• Select fan mounting type suited to space (wall, ceiling, roof) and environmental exposure.
• Choose materials resistant to humidity, grease, or dust, depending on the application.
• Balance noise vs capacity - especially in domestic or guest-facing settings.
• Ensure ease of access for cleaning and servicing.
• Where relevant, pick units with safety features like shutters, fire rated parts, or smoke detection integration.
