CFM is short for cubic feet per minute (cu ft/min). Fans are provided in HVAC and Refrigeration systems to distribute conditioned air, to provide ventilation or to exhaust un-wanted air. - As demand for product increased CFM Fans Pty Ltd was established. ME Mechanical efficiency (or Total efficiency). If multiple values are listed, choose the airflow (cfm) shown on the mechanical plans and 0.1 in. If a multi-speed fan is selected for a mechanical ventilation system, one should make sure that the ratings are at the revolutions per minute (rpm) range that the fan will be used.
