• New air-flap outlet technology for high airflow
  • Easy mounting
  • Protection type/Environmental ratings by independent testing agencies (VDE & UL)
  • Two optional systems for optimal airflow (FPI/FPO)
  • Industry-common enclosure cut-out sizes (5 sizes)
  • Single filter mat system design

  • Filter fans are used to provide "cooling" by forced air-circulation in enclosures and cabinets containing eletrical/ electronic and other components. The interior temperature of an enclosure can be reduced by channelling cooler, filtered outside air into the enclosure, thus expelling hot inside air. The resulting airflow prevents formation of localized hot pockets and protects electronic components from overheating.

    The Filter Fan Plus series encompasses a new air-flap technology on the air outlet side, thereby reaching an unparalleled high degree of airflow. A unique ratchet mechanism is used for easy installation. It provides safe and secure mounting while guaranteeing a tight seal. Depending on the requirements, there are two optional systems available – the FPI or the FPO system (FPI = "in", FPO = "out"). The FPI system is the more commonly known installation system, where a filter fan located in the lower part of the enclosure draws cleaner, cooler air into the enclosure (airflow direction "In"). This system consists of a filter fan and exhaust filter. On opposite, with the newer FPO system, the filter fan will be located in the upper area of the enclosure to draw warmer air out of the enclosure (airflow direction "Out"). The FPO system consists of an intake filter and exhaust filter fan. The Filter Fan Plus series has been designed for indoor use.
