    Suction is measured in water lift or inches of lift mercury(hg). Airflow is measured in CFM. You need a balance between the 2. Increasing the diameter of your hose will increase the CFM but may decrease the water lift depending on the size of your vacuum motors or blower. You don't want your auction to go below 10 inches hg or roughly 135 inches water lift. Any increase to your airflow (CFM) without dropping your suction too much will allow longer hose runs and will leave carpets drier. Which is why truck mount guys run 2.5 inch hose or four to the door for the first 50-100 feet on large jobs
