Certified commercial smoke spill fans are engineered with Class H motor insulation to operate continuously for either 2 hours at 250°C, or 2 hours at 400°C, depending on the specific local fire-code compliance and building life-safety requirements.
In a fire emergency, preserving human life by maintaining a smoke-free escape route supersedes protecting the equipment. Smoke spill motors are hardwired to bypass all VFDs and thermal overload relays, intentionally running the motor to destruction rather than tripping and allowing the building to fill with toxic smoke.
