Product Features & Fitment

Engineered with a heavy-duty rolled steel body measuring 6.5" in diameter, the Century B221 is optimized for long-life performance in aeration and air-handling equipment. Its PSC design delivers efficient single-phase operation, while dual voltage rating (115/230V at 8.0/4.0 Amps) permits flexible power connections. The TENV enclosure prevents airborne dust, grain chaff, and moisture from penetrating internal motor windings, while integrated automatic thermal overload protection protects the motor against thermal stress during extended operational cycles.
