Ventilation fan buying guide
Choose an extract or supply fan in three steps: calculate the airflow the space needs, choose a duct diameter that carries it at an acceptable velocity, then choose a fan that delivers that airflow at the static pressure of your duct run. The duct / CFM calculator does the first two steps.
Airflow by room type
Multiply room volume by air changes per hour: about 6 for bedrooms and offices, 8 for living rooms and shops, 10 for bathrooms, 15 for domestic kitchens and 15–30 for commercial kitchens and gyms (check municipality and Civil Defence requirements for regulated spaces). A 2.5 × 2 × 2.8 m bathroom at 10 ACH needs about 140 m³/h; a 100 mm fan is the usual choice.
TT or VKMz
| Series | Sizes | Max airflow | Best for |
|---|---|---|---|
| VENTS TT (mixed-flow) | 100 / 125 / 150 mm | 187 / 280 / 520 m³/h | Short, simple runs; bathrooms, small kitchens; two-speed; lowest cost |
| VENTS VKMz (centrifugal) | 100–315 mm | 250–1,540 m³/h | Longer runs, filters, grilles; offices, shops, small warehouses |
'Max airflow' is at zero static pressure; a real installation with a few metres of duct, a bend and a grille delivers roughly 60–75% of it, so allow margin. Full worked examples in the ventilation fan size guide.
Installation notes
- Match the duct diameter to the fan spigot — never neck down.
- Use rigid duct where possible; keep flexible duct short and taut.
- Provide a make-up air path; an extract fan needs replacement air.
- Fit a backdraught damper on external outlets to keep hot air out when the fan is off.

Why no prices on VENTS fans?
Stock and pricing vary; WhatsApp the model for a current quote.
Mixed-flow or centrifugal?
Mixed-flow (TT) for short straight runs; centrifugal (VKMz) where there is duct length, filters or grilles adding resistance.
Do you sell ducting and grilles?
Not in the online catalogue; they can be sourced with your fan order.
Do you deliver to all Emirates?
Yes — next business day for fans.
