We designed this calciner supply fan for a high-temp rotary kiln application. Featuring a radial tipped fan with a v-belt drive and a unitary base, it withstands temperatures up to 475°F. This heavy-duty, radial tip fan moves high volumes of air at low static pressures with high efficiencies.

The calciner supply fan application includes a rotating drum inside an externally-heated furnace, reaching extremely high temperatures that must remain even across the surface of the drum. This supply fan pulls clean, ambient air in to dry the material that enters the drum from the opposite end. Because calculations for the drying process are complicated, we designed this fan with a bit of extra margin to leave room for the extra speed it might need to accommodate.
