System showing higher static than design. Check for closed dampers or fan operating off curve?
Watch out
Don't assume catalog CFM achievable in all conditions. Don't increase fan speed without checking motor capacity. Don't ignore high static pressure readings.
Check
Design CFM and static pressure?
Fan curve at that operating point?
Actual system resistance higher than design?
