Roof Fan Vertical Constant Pressure Control – DVA 220 EC O CRK 02
The Ruck roof fan (DVA EC O CRK series) with energy-efficient EC motor features a vertical airflow direction and is equipped with integrated constant pressure control. This DC motor is infinitely adjustable via a 0–10 V signal. The roof fan comes standard with a working switch and is suitable for demand-controlled ventilation to automatically maintain the pressure level in your ventilation system. This makes the fan perfect for use with sensors such as a CO₂ sensor.
High Efficiency
The roof fan includes an integrated working switch and electronic temperature monitoring to prevent overheating. The housing is made of high-quality aluminum (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 differences. The powerful EC motor ensures reliable and energy-efficient operation.
