110-Volt Fans for Use in Kilns

Advice on finding fans that will perform in a drying kiln. July 3, 2008

I'm looking for recommendations on small fans that will work inside a kiln environment (~140F). Hardware store fans burn out pretty quickly. The kiln suppliers seem to specialize in 220v. Any good 110v fans out there? I make numerous temporary kiln structures for odd shaped projects, and need to be able to keep the air moving reliably.

The fans Nyle sells for L200's can be connected for either 110v or 220v. If you use 110V you need to use a different calibrated overload switch.

I use Dayton fans from Grainger. 10" round. 665cfm 110 volt, and they are ok temp wise. 4wt44 might be the model #, if not it’s close. They have two fans that will work that are this size, the difference being one has the cord and one doesn’t.

We use similar fans in other products that we make. Not kilns. The rating shown is based on free air and no resistance. In real life in a machine or kiln, you have to de-rate the performance about 50% or more when blowing through a stack of lumber or coils. The cost per CFM air moved is relatively high but the fan is quiet, if that is a concern.
