Verify voltage, current, starting behavior, alarm contact, airflow direction, noise and replacement availability. A fan cannot compensate for an enclosure that is overloaded, poorly sealed or exposed to an ambient temperature beyond its rating.<\/p><p>Keep a service record for filter cleaning, bearing noise, airflow alarms, thermostat settings and cabinet temperature.
