Filtration

Fan Control


Typical initial resistance of a Gore Cooling Filter is between 50-100 Pa and increases over its life time up to 200-250 Pa. In addition to this the resistance of the electronic fan has to be considered. Radial fan airflow/pressure characteristics typically operate in this same range. Both forward or backward curved impellers are available. Forward curved impellers require special housing, backward curved impellers only require a box. Both radial fan types should be placed behind the filter to protect them from ambient contaminants.

The fans should be set to ensure minimum temperature fluctuation within specified ranges. Control of the internal temperature is influenced by many variables including: ambient temperature, solar radiation, heat load and filter resistance. These variables are addressed by using fan control logic that offers either simple speed control or advanced (thermostatic) features depending on system requirements.

Gore Applications Engineers can help you to select the appropriate fan type and position to optimize the life of your electronics and filter.
