We know that a good vacuum has a balanced CFM and water lift rating so what do good numbers look like? A strong air flow rating is around 125 CFM and higher. This is strong enough air flow to pick up most anything you may work with including dust from 5″ or smaller grinders.3 Sept 2019

Does vacuum pump CFM matter?
CFM (Cubic Feet per Minute) Yes. This is how many cubic feet per minute of free air the pump will move. A pump with higher CFM rating will help you get to full vacuum quicker. Higher CFM does NOT mean better vacuum, only faster evacuation.
How many CFM vacuum pump do I need?
The CFM (Cubic Feet per Minute) on HVAC vacuum pumps is how fast it can pump out air and can vary between 2-10 CFM. 5-CFM is good for small to medium-sized residential HVAC units. For large 10-15 ton units, it would be better to have 8 or 10-CFM pump.3 Jan 2022
