Stego 01870.0-30 Exhaust Filter Fan
Price: $110.11

The Stego FPI 018 series 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.

  • FPI - Airflow direction in
  • New air-flap outlet technology for high airflow
  • Single filter mat system design
  • Easy mounting

Stego 01804.0-00 Exhaust Filter Fan
Price: $282.98

The Stego FF 018 series are used to provide an optimum climate in enclosures. The interior temperature of an enclosure can be reduced by channeling cooler filtered outside air into the enclosure thus expelling heated internal air. The resulting air flow prevents formation of localized heat pockets and protects the electronic components from overheating.

  • Intake and exhaust hoods prevent direct infiltration
  • Self-adhesive seal
  • High air volume
  • UV resistant plastic

Stego 01821.0-00 Exhaust Filter Fan
Price: $222.75

The Stego FF 018 series can be used in outdoor enclosures where warm air has to be dissipated. A protection type of IP55 is achieved due to the special design of the hood and the use of fine filter mats. The plastic used for the hood of this filter fan is highly weather and UV light resistant.

  • Weather and UV resistant
  • Lockable outer door
  • Quick and easy filter change
  • Impact resistant
