• Less energy use, resulting in lower energy costs
• 100% speed controllable
• Pre-wired potentiometer (0-10V) that allows you to easily find the desired working point.
• Ventilation on demand - easy to adjust ventilation rate to actual need
• Low sound level throughout the entire fan performance range
• Integrated motor protection
• For mounting on external walls
• Useful where internal space is limited
The RVF models are exhaust-air fans for installation on external walls. The unit consists of an impeller with backward-curved blades and a casing in galvanized sheet steel with a white powder-paint coating. All ambient noise created by the fan is kept outside the building if it is installed on an external wall.
EC
EC technology is intelligent technology, using integral electronic control which eliminates the slip losses in the motor and ensures that the motor always runs at optimal load and guarantees that the proportion of energy utilized effectively is many times higher and the energy usage considerably lower compared with AC motors.
EC fans are notable for their economical use of energy and excellent ease of control. They can be varied in speed to match the airflow demand, and operate at high efficiency levels. For the same air volume, they consume distinctly less energy than AC fan drives.
Another special feature of EC fans is their energy-saving potential not only at full load, but especially at part-load. When operating at part-load, the energy used is much lower than with an asynchronous motor of equivalent output.
Reduced energy usage guarantees a drop in operating costs.
