Air Motion Functionality

The environment friendly vitality a WC exhaust fan is measured in cubic toes per minute (CFM). That’s the quantity of air that the fan will suck out of the rest room inside one minute.

As a standard rule, a rest room must have an exhaust fan that pulls out a minimal of fifty CFM or greater. To take full good thing about your fan’s cubic foot per minute performance, it helps to supply ample consumption, or make-up, air by leaving the rest room door barely open whereas the fan is working.

One methodology to think about the information and better standardize CFM and noise is to convey the two numbers collectively. The intersection between sones and air amount (dividing sones by CFM) affords you a larger view a WC fan’s price than just by noise or amount alone. Lower CFM-per-sone numbers are greater. For example, a fan rated at 1 sone and 1 CFM would produce a CFM-per-sone rating of 1. If a fan with the similar sones have been ready to drag out 2 CFM, its CFM-per-sone rating might be 0.5.
