Choosing a roof extract fan depends first on the airflow required for your hood, which is itself linked to the hood dimensions, the type of cooking and the extraction ductwork: duct diameter and length, number of elbows and discharge height. A long run of ductwork or several elbows increases pressure losses: never size your fan on the maximum airflow shown alone, the actual airflow depends on the whole installation.
Our range goes from the T11 roof fan at 1,100 m³/h, for a small installation, up to the T71 4T roof fan at 22,000 m³/h for large catering kitchens. In between, the T32, T36, T40, T45, T50 and T63 series cover intermediate requirements, with stated airflows of between 2,000 and 14,000 m³/h depending on the model.
Models in single-phase 230V suit many small and medium power installations, up to the T45 series. For higher airflows, from the T32 series upwards and especially above 4,000 m³/h, the roof fans are also available in three-phase 400V. Always check the power supply available on site before choosing your model: moving from single-phase to three-phase is not a minor change on the electrical board.
A large part of our SAFTAIR range is designed to the F400/120 smoke extraction standard, meaning resistance to 400°C for 120 minutes. F400/120 is not interchangeable with other fire resistance classifications: check the exact standard required for your installation before placing your order, particularly if your project is subject to specific smoke extraction regulations.
For premises cooking over wood fire, the T25 roof fan (2,500 m³/h, 230V) is specifically stated as compatible with this type of cooking and supplied with a speed controller. Wood fired cooking generates different temperatures and residues to standard cooking: do not automatically transfer a standard model to this type of installation without checking its suitability.
A roof fan with horizontal discharge extracts air sideways. A roof fan with vertical discharge directs the airflow upwards, which can help carry smoke and odours away from the roof and neighbouring buildings. The choice depends mainly on the building layout and local planning or neighbour constraints.

| T32 single-phase | 2,000 m³/h | 230V single-phase | F400/120 | 25 kg |

Consider the accessories that go with your roof fan: roof upstand, duct mounting kit, vertical deflector kit, protective cowl, roof flashing or the CR1 fire resistant cable for connecting smoke extraction models. For installations requiring a remote motor without a roof outlet, our extraction fan boxes can be an alternative.
To determine the right airflow and model, let us know the hood dimensions, the cooking equipment, the duct diameter and length, the number of elbows and the planned location for the fan. This information will allow us to point you towards the solution suited to your installation.
A roof extract fan is fitted on the roof or on a wall and discharges air directly outside. An extraction fan box locates the motor outside the kitchen but without a roof outlet, useful when there is no roof access available. The choice depends mainly on your building layout and the space available for the motor.
In our range, single-phase 230V covers airflows up to around 5,200 m³/h (T45 series). Beyond that, particularly from 7,500 m³/h upwards, models are offered in three-phase 400V. The choice also depends on the power supply actually available on your site: check this before ordering.
The F400/120 standard denotes resistance to 400°C for 120 minutes, relevant for installations subject to smoke extraction regulations. It is not interchangeable with other fire resistance classifications. Always check with your consultant or installer which exact standard is required for your project before choosing your model.
Not necessarily. In our range, the T25 roof fan (2,500 m³/h, 230V) is specifically stated as compatible with wood fired cooking and supplied with a speed controller. For this type of cooking, it is best to choose a dedicated model rather than a standard roof fan, as the residues and temperatures generated differ from standard cooking.
The airflow stated on a roof fan corresponds to free airflow, measured without any ductwork constraints. In the actual installation, the length of the ductwork, its diameter and the number of elbows create pressure losses that reduce this airflow. You should never size based solely on the maximum airflow of the product, but take the whole extraction system into account.
Regular maintenance of your installation is essential to limit odour nuisance (a legal requirement, at least once a year). To further reduce odours, installing vertical deflectors is strongly recommended. As well as reducing noise nuisance, they allow smoke and odours to be discharged higher and further, helping them disperse in the air and limiting their impact on neighbours.
