Special Function Circuit Diagrams


AC Fan Speed Control Unit

The dual channel phase control unit allows the user to control fan speed for single or multiple fan assemblies.
Part number: OA11/22


AC Smart Fan - Temperature Control

TEMP Control Series’ smart thermal control reduces power consumption by increasing or decreasing fan speed according to the ambient air temperature but only requires a simple AC input. This results in up to a 30 percent energy savings over similar-sized, single speed fans. Also, the overall noise profile is significantly reduced.
Part number: OA109AP

SpotCool DIN Rail

Available only from Orion Fans, the new SpotCool DIN rail mount fan is the ideal solution for cabinet or enclosure applications that need supplemental cooling in specific areas. This fan easily snaps onto an existing DIN rail or comes with its own 6-inch rail for easy placement and mounting.

Model number: OD1232-SPOT-DIN (120x32mm) (4.7"x1.25")


Dual Voltage

For worldwide applications, these fans operate on either 115VAC/230VAC.

Available on the following AC Fans Series numbers:
OA825 (80x25mm) (3.15"x1")OA80 (OA80x38mm) (3.15"x1.5")OA92 (92x25mm) (3.62"x1")OA938 (92x38) (3.62"x1.5")OA125 (120x25mm) (4.7"x1")OA109 (120x38mm) (4.7" x 1.5")OA119 (127x38mm) (5"x1.5").


AC Crossaxial Blowers

Provides an even, laminar airflow for applications that require even cooling like printing or displays. Large crossaxial blowers are used as "Air Curtains" in facilities to prevent the influx of outside air through an opening in to a heated or cooled area.

OAB30 Series: (96 – 366mm) (14 – 60cfm)     OAB40 Series: (98 – 366mm) (21 – 70cfm)
OAB50 Series: (98 – 437mm) (24 – 110cfm)   OAB60 Series: (184 – 525mm) (63 – 180 cfm)


Motorized Impeller

Motorized Impellers are designed for applications in electronics and other equipment where high reliability, high airflow, high static pressures, and limited space are primary considerations. Ideal applications include electronic cabinet cooling, telecommunications, air filtration, networking and ventilation systems.

OAB190 (190x77mm) (7.5" x 2.8")  OAB220 (220x71mm) (8.7" x 2.8")


All Metal Construction

Orion’s all metal fans are ideal for military, chemical, process control and industrial applications. Because plastic fan blades can be susceptible to severe conditions such as high temperatures or chemical gases, metal fan blades are preferred in harsh environment applications for their durability.
