Vertical Roof Fan with Constant Pressure Control – DVA 280 EC O CRK 01
The Ruck roof fan (DVA EC O CRK series) features an energy-efficient EC motor with a vertical discharge direction and integrated constant pressure control. This DC motor is continuously adjustable via a 0–10 V signal. The roof fan comes standard with a service switch and is ideal for demand-controlled ventilation to automatically maintain constant pressure levels within your ventilation system. This makes the fan perfectly compatible with sensors such as a CO₂ sensor.
High Efficiency
The roof fan is equipped with an integrated service switch and electronic temperature monitoring to prevent overheating. The casing is made of high-quality aluminium (AlMg3) and is hinged for easy inspection and maintenance. The fan features backward-curved blades for higher efficiency, lower power consumption, and reduced noise levels at higher pressure differentials. The powerful EC motor ensures reliable and energy-efficient operation.
