    Model RSF and BCF Selection The RSF and BCF selection charts are different from all other selection charts. For these models, the cfm values are at the left side of the chart in a single column and the rpms are in the performance boxes. It is just the opposite for other models. The reason for this is that the RSF and BCF models are forward curved, ...

    F AN SELECTION BASED ON F AN APPLICA TION Direct Drive vs Belt Drive Direct drive fans are economical for low volume (2000 cfm or less) and low static pressure (0.50 in. or less). They require little maintenance and most direct drive motors can be used with a speed control to adjust the cfm. Belt drive fans are better suited for air volumes above 2 ...

    Determining Static Pressur e (Ps) The pressures generated by fans in ductwork are very small. Yet, accurately estimating the static pressure is critical to proper fan selection. Fan static pressure is measured in inches of water gauge. One pound per square inch is equivalent to 27.7 in. of water gauge. Static pressures in fan systems are typically ...

    Motor Horsepower The motor horsepower for direct drive fans is always sized by Greenheck and does not require further consideration. For belt drive models, the catalog identifies which horsepower is recommended. However, there are times when it is wise to bump the horsepower one size. For example, the hp recommended for the GB-180 at 810 rpm is 1/3 ...

    Installation To ensure proper fan performance as cataloged, caution must be exercised in fan placement and connection to the ventilation system. Obstructions, transitions, poorly designed elbows, improperly selected dampers, etc., can cause reduced performance, excessive noise, and increased mechanical stressing. For the fan to perform as published ...

    F AN PERFORMANCE System Dynamics For a given flow rate (cfm), an air distribution system produces a resistance to airflow (Ps). This resistance is the sum of all static pressure losses as the air flows through the system. Resistance producing elements include ductwork, dampers, grills, coils, etc. A fan is simply the device that creates the pressur ...

    Combining Fan and System Dynamics The previous two sections introduced fan curves and system resistance curves. This section will show how these relate to each other to provide an understanding of the way the fan-system operates as a complete entity. Remember that a fan curve is the series of points at which the fan can operate at a constant rpm. L ...

    Adjusting Fan Performance There is a direct relationship between cfm and rpm within a system. Doubling the fan rpm will double the cfm delivered. Sample problem: The figure on page 21 showed a fan curve at 700 rpm which had an operating point of 1000 cfm at 0.25 in. Ps. What rpm is required to move 2000 cfm through the same system? Solution: Within ...

    In a steady-state system, as the fan rpm changes, cfm, Ps and BHp (horsepower) also change. The equations below, known better as fan laws, show the relationship between these performance parameters. cfm New = rpm New x cfm Old rpm Old Ps New = ( rpm New ) 2 x Ps Old rpm Old Bhp New = ( rpm New ) 3 x Bhp Old rpm Old The first two equations have alre ...
