Description
Helicoidal wall fans with square painted panel and external rotor single phase motor.
Characteristics
- The external casing and the impeller are made of steel with polymeric coating;
- Black colour;
- Air flow: from the engine to the fan;
- Fan is installed on the wall surface by means of a square mounting plate;
- The fan casing is equipped with an external water-tight terminal box for electrical connections;
- Motor with integrated thermal protection;
- 220–240 V, 50/60 Hz power supply;
Use
Combined ventilation systems for air supply and extraction, designed for applications requiring high airflow rates with low system resistance.
EVOV fans can be used both for direct air extraction and for room pressurization.
Their construction configuration is suitable for outdoor wall installation, providing good flexibility of use for a wide range of ventilation applications.
Dimensions
All measures are in mm.
