Axial Fan Heater

Farnam Custom Products has developed a unique and easy-to-install Axial Fan Heater (Series AF20). This air heater mounts directly to square axial fans. It even uses the same mounting holes for the fan itself. Attachment couldn't be simpler. In addition, the AF20 heater housing functions as a guard for both the heater and the fan.

These standard heaters are available in several sizes, a broad range of wattages, and with custom features. They are ideal for a wide range of drying, curing and warming applications typically found in film processing, lab and medical instruments.

All our Axial Fan Heaters are standard products. They can be easily tailored to fit your requirements. Just use the part number to specify the features you need.

The 3.1 and 4.7 size axial fan heaters are UL recognized components under UL file number E154979. The 2.4 size is not UL approved.
