WebShop Greenheck CSP-A A direct drive, inline-mounted fan designed for exhaust, supply or return air applications where low sound levels are desired. The unit features an insulated, galvanized steel housing with a forward-curved centrifugal wheel. Ideal applications for this model are clean air including intake, exhaust, return or make-up air. WebMay 17, 2024 · Formula: SP2 = SP1 X (CFM2 ÷ CFM1)² or SP2 = SP1 X (RPM2 ÷ RPM1)² What it means: A 10% increase in CFM will result in a 21% increase in static pressure. Think about that. A small increase in airflow creates a significant increase in duct pressure. This increased pressure will be evenly distributed across components like coils and filters.

Webpressure, and input power as measured per AMCA Standard 210. It does not take into effect the efficiency of the drive (belt drive) or the motor. Fan efficiency is defined as the air power divided by the fan input power. Both Static and Total Efficiency can be calculated from fan performance data as follows: Where: CFM 3= Fan flow rate, ft /min
WebGreenheck Product Application Guide 2 ¨ Fan Application No. FA/115-02 pressure across both fans will be the sum of the individual total pressure of each fan. Total pressures are used instead of static pressure because the fans can actually be different sizes and a change in fan or connecting duct areas has an influence upon static pressure values.
