Axial Fan Heaters

Axial Fan Heater

US & Canada UL Recognized Component
  • Axial Fan Heaters (Series AF-20) mount directly to square axial fans. The AF-20 heater housing uses the same mounting holes and functions as a guard for both heaters and fans. (Fans available separately.)
  • Axial Fan Heaters are available in several sizes with a broad range of wattages and custom features. They are ideal for drying, curing and warming applications typically found in film processing, lab, and medical instruments.
  • All Axial Fan Heaters are UL recognized components under UL file number E154979.
