Below you will see reference to 'Rated Fan Flow'. This number is determined by one of two methods.
1. The ton rating of the condensing unit. i.e. 3 Ton. The formula is then ((ton*400)=*allowed leak rate) example--((3*400)*.15)=180 CFM
2. The Output BTU of the furnace example-- ((64000 * 21.7) * .15) / 1000=208 CFM
