Thermal Edge Filtered Fan Packages are designed to be your economical answer to cooling electrical enclosures in environments that are not extremely harsh, where humidity is not a concern and temperatures slightly above ambient are acceptable.
Thermal Edge Filtered Fan Packages are available with UL Types 12, 1 and 3R ratings. UL Type 3R models are intended to keep the elements out of your enclosure while maintaining free air movement from your filtered fan packages.
