Answers

Answer: 
This fan is rated for use with different horsepower drive packages. The stronger the horsepower the more cfm it produces. SP is static pressure, which is resistance against the air flow. Ducting will create SP as will filters. The higher the SP the less cfm you will get from the fan. If you require assistance with sizing I would recommend calling our HVAC tech team at 800-472-4643.
