If the ambient temperature is always lower than the temperature required in the electrical enclosure, then Filterfans® represent an economical solution for thermal management of electrical enclosures. Filterfans® are the ideal solution for clean, non-hazardous environments with an acceptable ambient (outside the enclosure) temperature range.

When the amount of heat being removed from your enclosure is minimal, the use of PFA Exhaust Filters can be effective.  This method usually provides less of a cooling effect than is necessary with today‘s components.

Important for the use of Filterfans®:

  • Use Filterfans® to force the surrounding air into the electrical enclosure, so that a slight overpressure builds up inside the enclosure.
  • The surrounding air enters the electrical cabinet exclusively via the Filterfans®, which ensures that it is filtered.
  • Install the Filterfans® in the lower third of the electrical enclosure and the exhaust filter as close to the top as possible. This assists the natural convection of the air and avoids hot spots within the enclosure.
