Output grille IP55 280mm DEKraft 35013DEK

The fan (with or without filter) draws fresh air from outside into the housing, thereby creating a slight positive pressure that leads to the removal of hot air through the exhaust grille. Air circulation homogenizes the temperature, and positive pressure helps prevent dust ingress. Side or roof mounting. Can be combined with a thermostat. Fans consist of an axial motor, protective covers on the front and rear surfaces, and a filter designed to retain dust particles. This filter can be replaced during operation without the risk of contact with the rotating element. The ambient temperature should not exceed 35°C and must be more than 5°C below the required temperature inside the housing. Filters equipped on the fans must be cleaned and replaced regularly. When determining fan flow, consider the pressure losses caused by the exhaust element (grille with filter, ventilation grille, or a simple opening).
