Why this extraction fan earns its place
The Combisteel FAN IN BOX 12/12 represents the practical middle ground for commercial kitchens: more capacity than smaller units, but not oversized for kitchens that don't need maximum airflow. The 12/12 sizing connects to standard 12-inch ductwork, which is widely used in professional kitchen installations and integrates cleanly with existing or planned ventilation systems. The fan comes pre-assembled in a robust enclosure, eliminating the need to source individual components and build a housing on site.
At 30 kg and 620 × 675 × 640 mm, it's sized to mount securely in ceilings, walls, or dedicated ventilation spaces without excessive bulk. The boxed design means the motor runs inside an insulated chamber, which contains noise and vibration while protecting the motor from the kitchen environment. During busy service, when multiple stations are generating steam and cooking odours simultaneously, this unit delivers the airflow needed to keep the kitchen clear and comfortable for staff.
Installation is swift: the unit is fully tested before it leaves the factory, so it's a case of positioning it, fastening it securely, and connecting the inlet and outlet ducting. The 12/12 is a proven size for hotels, restaurants, school kitchens, and food production facilities where the extraction load is genuine but not extreme. It runs quietly relative to its capacity and is built to handle years of daily use without fuss.
