Ooerre T° Control www.oerre.it • IP43, IP44, IP54 or IP55 protection degrees; • Body and grille made of ABS self-extinguishing material grey RAL 7035; • In accordance with European Standard EN 60529, EN 60335-2-80. SYSTEMA VENTILATION • Complete ventilation system; • Kit composed of: 1. complete fan with grille and filter; 2. filter for air exhaust grille; 3. grille for air exhaust TECHNICAL DATA Model Code IP Voltage Frequency Colour Flow rate (m3/h) Power Nom.

This process has concrete and significant benefits in terms of aging and operation quality of the products: the overpressure prevents entry of dust inside the panel, thus ensuring better operating conditions of electrical and electronic equipment inside. Working under pressure, the fan blows air into the room at ambient temperature, granting benefits in terms of long lifetime and reliability of the appliance. This one is less mechanically strained compared to the extraction operation where air would be heated up by the previous cooling process of the internal circuits. Recommended to keep the fan and the exhaust grille as far as possible. A proper ventilation and regular maintenance of filters grant efficient cooling of the electrical equipment achieving better quality and longer lifetime.
