performance is adequate, recent industry trends have seen the emergence  
of 12-blade wheel designs where customers demand higher mechanical  
efficiency and lower sound levels.  
Model QEM and QEP plenum fans feature a 12-blade aluminum airfoil  
construction wheel. As demonstrated in Figure 1, this 12-blade design  
meets customer needs by providing higher efficiency, lower sound levels  
as well as lower energy consumption.  
Greenheck’s 12-blade wheel design features extruded aluminum blades  
up to and including size 49, while the largest sizes utilize laser cut, die-  
formed aluminum blades. The two performance examples below demonstrate the  
superior performance of the 12-blade design.

Figure 1 plots the fan performance and efficiency of  
two fans running at the same rpm. Increased wheel  
efficiency allows the 12-bladed fan to produce more  
airflow while using less energy.

Improved Sound Quality  
A sound spectrum with a dominant tone can be  
annoying to a listener. Greenheck’s 12-bladed wheel  
provides balanced sound power levels across the  
octave bands. This results in sound that is pleasing to  
the listener.

Air Plenum Design Guidelines  
Effects of Air Density  
To assure optimum performance and be able to use  
the system effect coefficients below, the following  
guidelines should be adhered to in the plenum design:  
Ratings in the fan performance tables and curves of  
this catalog are based on standard air: clean and dry

29.92 in. of mercury. A change in elevation, temperature  
or the type of gas handled will affect density. A fan  
running at a constant speed and installed in a fixed  
system will experience changes in pressure output and  
horsepower consumption if the density of the airstream  
varies. The air volume delivered by the fan will remain  
constant regardless of air density.  
1. Flexibleconnectionsattheinletarerecommendedto  
isolate vibration. The inlet connection can be square  
(connected to the inlet panel) or round (connected  
to an optional inlet collar).  
2. Plenum walls should be at least one-half of a wheel  
diameter away from the fan.  
3. Dampers or coils should be at least three-quarters  
of a wheel diameter away from the fan to assure an  
even velocity distribution through them.

4. For fans operating in parallel:  
Have one wheel diameter clearance between  
adjacent fans.

Airstream Temperature:  
Installation Elevation:  
Reduction in cataloged air performance due to a plenum  
around the fan is called a system effect. System effect  
is a pressure loss, which must be added to the total  
external static pressure of the duct system in order to  
make the proper fan selection from catalog data. The  
pressure loss calculation is based on the velocity of  
the air in the discharge ductwork. As shown below, it  
is derived by multiplying the appropriate coefficient by  
the velocity pressure.

Direct drive construction offers many advantages for commercial or  
industrial air handling applications.  
- Reduced maintenance (no belts and shaft bearings to service)  
- Compact housing design requires a smaller footprint  
- Low vibration  
- Suitable for clean air application (no belt or bearing residue in airstream)
