The Ruck® roof fan metal (DHA EC P series) with energy-efficient EC motor has a horizontal discharge direction and an isolating switch. This EC motor can be operated with a variable Ruck® potentiometer (MTP 20) or by 0-10V control. In addition, demand-controlled ventilation is possible via constant pressure control (CON P1000), to keep the pressure level in your ventilation system constant, or via a CO2 sensor.
The roof fan has an isolating switch and built-in temperature control to prevent burn out. The metal roof fan is mounted directly on a Ruck® roof socket (DSF series) or a sound-insulated plinth silencer (DSS series). In addition, the roof fan is equipped with rearward curved vanes. The advantages of this are that the fan has a higher efficiency, a lower power consumption and a lower noise level at higher pressure differences. The Ruck® DHA EC P series is available with capacities ranging from 670m³/h up to 18770m³/h.
