Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.2. The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return airduct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.3.
