Direct Drive Model Selection

The following performance charts are for the selection of QEID mixed flow inline fans. All charts are organized by fan size and nominal motor RPM. Within each chart, there are a series of solid black lines with corresponding dashed lines. The solid black lines represent the fan curves for each fan and are broken down by partial wheel widths. Minimum, maximum, and 10 percent intervals are shown. The dashed lines are brake horsepower (Bhp) curves and are also labeled by percentage wheel width.

Example Selection: 1,700 cfm @ 2.0 inches Ps wg.

To make a selection, start by finding a size and RPM that will attain the design static pressure (Ps). Next, scan for fan sizes and RPMs that meet the CFM requirement at the design pressure. The intersection point of the static pressure and CFM needs to be between the minimum and maximum percent wheel width for each fan.

To determine the partial wheel width and brake horsepower, start at 2.0 inches Ps and move across the graph until intersecting the next percent wheel width beyond the required 1,700 cfm, point A. For this example, the next largest percent wheel width is 70. Draw a vertical line from point A that crosses the 70 percent Bhp curve. In this case, slide vertically downward from A to point B. From point B, read the Bhp on the right vertical axis of the chart. The Bhp for this point of operation is 0.9 Bhp. Note: If the operating point falls between two partial wheel

width curves, select the next larger wheel width at the same pressure. This will result in more CFM as compared to the original design requirements. Wheels are available in 5% partial width increments.

Minimum Percent Wheel Width

Maximum Percent Wheel Width

Sound data values are provided for both the inlet and outlet of the fan and are based on 100 percent wheel widths. Values shown in the tables are based on the design static pressure. If the design static pressure is not listed in the table, the sound power levels need to be interpolated from the values found on either side of the design static pressure. If the design static pressure exceeds the maximum pressure listed in the table, then the maximum values in the table should be used.

Example: 1,700 cfm @ 2.0 inches Ps wg. with 1770 fan RPM

Since 2.0 inches Ps exceeds the maximum static pressure in the table, the sound power levels for the maximum static pressure should be used. Sound power levels should be interpolated for pressures between those listed.

Effect of Air Density - Temperature and Elevation

Ratings in the fan performance tables and curves of this catalog are based on standard air (clean, dry air with a density of .075 pounds per cubic foot, barometric pressure at sea level of 29.92 inches of mercury, temperature of 70°F). Selecting a fan to operate at conditions other than standard air requires an adjustment to both static pressure and brake horsepower.

A cubic foot of air has a constant volume regardless of temperature or elevation. However, air density changes with non-standard temperature or elevation. Therefore, when selecting a fan to operate at a non-standard air density using standard air density tables and curves, corrections must be made to parameters affected by air density. These parameters are static pressure and brake horsepower.

For example, a size 30-QEID mixed flow fan is to deliver 20,000 CFM at

5.0in. static pressure. Elevation is 3000 feet, temperature is 100°F.

The 5.0 in. static pressure refers to

( p

the static pressure at the operating air density, in this case at 3000 feet, 100°F. Intuitively, we realize that at higher than standard elevations and temperatures, air density will be lower than standard. Therefore, we must determine what static pressure at standard air density will equate to 5.0 in. static pressure at our

Temperature °F

operating density. Since standard air density is greater than operating air density in this case, we would expect the static pressure after applying the correction to be greater than the original operating static pressure.

The table gives air density correction factors for non-standard temperatures and elevations.

Adapted from AMCA Standard 99-09, section 0200, Charts and Tables, with written permission from Air Movement and Control Association International, Inc.

The example below shows the relationship of fan performance at sea level and at 3000 ft. elevation and 100°F.

EXAMPLE

The following example shows how to properly select the fan described above:

1. Since the air volume delivered by the fan is not affected by density, airflow remains 20,000 CFM.

2. Determine correction factor from chart for an elevation of 3000 feet and air temperature of 100°F. The correction factor is 0.848

3. Divide the specified operating static pressure by the correction factor to determine the standard air density equivalent static pressure (Corrected static pressure = 5.0 in. ÷ 0.848 = 5.9 in. Ps).

4. Refer to the fan performance table for a 30-QEID. At 20,000 CFM and 5.9 in. Ps: Fan RPM = 1770, Percent Wheel Width = 70, Actual Volume 20,800 CFM, Bhp = 31.

5. Since the horsepower selected refers to standard air density, this must be corrected to reflect actual Bhp at the lighter operating air. Operating Bhp = standard Bhp x 0.848, or 31 x

0.848 = 26.3 Bhp. 30 HP motor would meet requirements.

If a fan is selected to operate at high temperatures, the motor must be of sufficient horsepower to handle the increased load at any lower operating temperature where the air is more dense. Assume the air entering the 30 QEID fan at start-up is 0°F. For 0°F and 3000 feet elevation the air density correction factor is 1.033. Bhp at 0°F = 31 x 1.033 = 32, therefore, a 40 HP motor is required.
