Commercial Extractor Fans

Which commercial extractor fan do I need?

• Inline duct fan: longer duct runs, ceiling voids and quieter offices; sits in-line within round duct. 180 to 3,000+ m³/h.
• Cased axial fan: ducted commercial extract or supply and services risers; in-line or ducted. Up to around 10,000 m³/h.
• Plate axial fan: through-wall extract for kitchens and workshops; wall or plate mounted. Up to around 11,000 m³/h.
• Roof-mounted fan: vertical discharge from kitchens and plant rooms; roof mounted. Up to around 45,000 m³/h.
• Box fan: space-tight and acoustic-sensitive supply or extract; in-line box. Up to around 5,000 m³/h.
• Twin fan: standby and duty resilience on 24/7 systems; in-line. Matched to duty.

Frequently asked questions

What's the difference between a commercial and domestic extractor fan?

Commercial extractor fans are engineered for continuous or near-continuous operation, higher airflow volumes and greater motor durability. They're rated for longer run times, higher ambient temperatures and harsher environments, suiting professional kitchens, workshops, warehouses, schools and public buildings. Domestic fans are designed for intermittent use in bathrooms and kitchens at lower airflow. For a domestic option, see our bathroom extractor fans.

What's the difference between axial and inline commercial extractor fans?

Axial fans move air in a straight line and suit short duct runs, wall or ceiling mounting and high-volume airflow. Inline fans sit inside the ductwork and are better for longer runs, ceiling voids and quieter operation. Mixed-flow inline fans add higher pressure for more complex duct systems.

What type of commercial fan do I need for a kitchen?

For commercial kitchen extraction you'll typically need a high-temperature rated cased axial or centrifugal fan with appropriate IP ratings for damp or greasy air. See our dedicated commercial kitchen extractor fans collection.

What size commercial extractor fan do I need?

Sizing depends on the room volume, required air changes per hour and the activity taking place. As a rough guide: offices need 6 to 10 air changes per hour, commercial kitchens 20 to 30, workshops and light industrial 10 to 15, and warehouses 6 to 10. Multiply room volume (length by width by height in metres) by the required air changes to get the airflow in m³/h, then choose a fan that meets or exceeds it. Our team can help, so get in touch for sizing advice.

Are commercial extractor fans suitable for industrial environments?

Yes. Industrial-rated extractors handle dust, heat, fumes, moisture and continuous operation in warehouses, workshops, manufacturing areas and plant rooms, built for higher duty and tougher conditions than domestic units.

Do commercial extractor fans need ducting?

Not always. Wall-mounted axial and plate fans can often exhaust directly outside. Inline, roof-mounted, twin fan and box units usually need ducting, especially in offices, plant rooms and ceiling voids where direct discharge isn't possible. Proper ducting improves performance, reduces noise and maintains efficient airflow.

Do you stock three-phase commercial fans?

Yes. We carry a wide selection of three-phase commercial and industrial fans from Systemair, S&P, Elta and Hydor. Three-phase motors are more efficient at higher power outputs and are standard on larger sizes (typically 315mm and above). Use the "Phase 3" filter on this page to view them.

Can I get next day delivery on commercial fans?

Yes. Most commercial fans in our range are held in stock and available for next working day delivery on orders placed before 12pm, Monday to Thursday.
