When specifying an exhaust system for your machine there are a number of considerations. The main minimum requirements that must be followed:
- CFM (Cubic Feet per Minute) or m3/hr (metric): This is the amount of air that a blower or exhaust system can move per hour of operation. The higher the CFM or m3/hr rating of the fan, the more air it will move.
