SX120BC Centrifugal Inline Fan, Belt Drive
** Please verify CFM, ESP, HP, Voltage, and Phase. **
After choosing a fan model from the Direct Drive or Belt Drive Performance Data sections, it is important to review the motor availability
charts in this section before specifying electric motors for your particular needs. Factors which influence the selection process are
discussed below.
Electric Power Considerations
First, determine the nature of the electric power feeding the motor. Is it single phase or three phase power? Next, determine the required
line voltage. Is it 115V, 230V, or 460V? Applications using 277V will require a transformer. If your HVAC application is in the U.S., the
frequency of the alternating current will be 60 Hz. All of North America and most of Central and South America use 60 Hz as does Saudi
Arabia. Most other countries in the world use 50 Hz.
Environmental Considerations
Standard motors supplied with fans are called Open Drip Proof (ODP) motors. Other types of motors may be required to meet specific
field conditions; high temperature (50°C) or Totally Enclosed (TE) are two examples. Hazardous environments require Explosion Proof
motors. Standard Explosion Proof motors are rated for Class 1, Group D, Div. 1 and Class II, Groups F and G, Div. 1 applications. Motors for
other classes and groups may also be available. Please consult your local PennBarry representative for information.
Unit Mounting
The Centrix’s versatile design allows for mounting at a variety of angles. When unit positioning necessitates motor mounting to the side
of the unit, Pennbarry recommends motors up to 2 HP. Selection of a higher HP motor may void warranty.
Variable Speed Motor Control
PennBarry offers Lek-Trol™ solid state controllers to alter the high speed of most direct drive motors by as much as 50%. If variable
speed is required, check the Lek-Trol™ availability table on the following page to verify that controllers exist for the fan model selected.
Remember, Lek-Trol™ controllers are currently only available for direct drive motors. Motors suitable for use with field supplied Frequency
Inverters Replace with (Variable Frequency Drives) can be supplied for belt drive models. Contact your local PennBarry representative.
High-Efficiency Motors
High-efficiency motors that comply with the requirements of the Energy Policy Act of 1992 are available.
Direct Drive Motor Ability
The following chart lists the various motor options available for each of the direct drive fan models. Once a fan model is selected, this
chart can be used to determine if a suitable motor is available. (If not, another selection may have to be made from the fan performance
charts). Look under the nominal RPM heading to determine which fans have 2-speed and 3-speed motors. Centrex Inliner direct drive
models (except size 085) are available with single and multi-speed motors. Multi-speed motors are designated V (1050 RPM), S (1300
RPM), and R (1550 RPM) (SX085R is an exception being a single speed motor). Q, Q1, Q2 (1725/1760 RPM) are single speed motors. A
single Centrex Inliner fan may be suitable for several requirements by a simple wiring chang
