RF/EC

Product catalog summary

Application
RF/EC roof fans are designed for ventilation systems in buildings with low air pollution levels, suitable for residential buildings, supermarkets, industrial halls, workshops, warehouses, toilets, garages, parking lots, and outhouses.

Construction
The fans feature rotors with backward blades made of plastic, and components such as the base and upper bowl are made of aluminum. They include a galvanized protective mesh and are designed for vertical operation, suitable for flat roof mounting, with a working temperature up to +60°C depending on the model.

Motor Specifications
The fans are powered by single-phase 230V, 50Hz or three-phase 400V EC motors with a 0-10VDC control input for smooth rotation control. Insulation classes vary by model, with IP44 and IP54 protection levels.

Technical Characteristics
Key specifications include airflow, pressure, speed, voltage, current, absorbed power, sound pressure level, operating temperature, weight, and regulator type. Models range from RF/EC-125/L to RF/EC-500T, with varying performance metrics.

Performance Curves
Graphs illustrate the relationship between airflow, absorbed power, and static pressure at different voltage levels, providing insights into fan efficiency and performance under various conditions.

Acoustic Characteristics
Sound power levels are provided for different frequency ranges at maximum, two-thirds, and one-third airflow capacities, highlighting the acoustic performance of each model.

Mounting Accessories
Various mounting accessories are available, including plates, anti-vibration components, and duct silencers, with specific configurations for different fan models.

ERP Characteristics
Details on energy-related product (ERP) characteristics include supplier name, article number, device category and type, drive type, reference flow rate, electric power input, static efficiency, and sound power level.

Electrical Accessories
Available electrical accessories include wall thermostats, duct thermostats, air quality sensors, humidistats, and regulators, with specific article numbers for each component.
