DUCT FANS are mostly used in low-to medium-pressure ducted systems with additional components such as heaters, filter boxes, dampers, etc. • Rectangular or round connection • Airflow up to 15.900 m3/h • High-efficiency EC-fans ROOF FANS are used to extract air in ventilation systems where the air has a low amount of impurities. Fan motors are protected from external objects. Roof fans are typically mounted with roof curbs and back-draft shutters. Demand control ventilation is available (for EC fans with 0-10V DC control) with Stouch controllers and CO2 /pressure sensors that regulate fan speed depending on CO2 levels/pressure. EC fans (controlled via 0-10V DC signal) can also be connected directly to constant pressure sensors or on/off switches. • Vertical or horizontal exhaust • Airflow up to 14.500 m3/h • High-efficiency EC-fans. KITCHEN FANS are used to extract air in ventilation systems where the air is up to 1200°C and has higher levels of humidity and impurities such as grease. The motors of these fans have a protection class of IP54. Units are equipped with easily removable grease trays and are user friendly. • For extraction of polluted hot air • Airflow up to 15.100 m3/h • High motor protection class: IP54/55
