Frequently Asked Questions View all FAQs
How do you order the correct replacement parts?

Before ordering replacement parts, make sure you have the fan model and serial number.

Where can I find instructions to wire a motor on my fan?

The nameplate of the motor includes a wiring diagram. Wiring diagrams can also be found beneath the motor image in our Buy Parts section. Simply click the wiring diagram icon to view it.

Can I install a thermostat?

Yes, but only if the thermostat has a simple on/off operation. Please note: if the thermostat varies the amount of voltage delivered, it will damage the motor and void the warranty.

Can I install my whole house fan vertically?

Comfort Cooler (CC) series whole-house fans may be mounted vertically, however, the AS and CSS shutters will not function properly in the vertical position. We do not carry a ceiling shutter for vertical installation. Vertical installation instructions.

The Go-To Ceiling Mounted Fan for Precision Air Movement

Since 1948, Triangle Engineering has been at the forefront of designing ceiling mounted fan solutions that balance powerful ventilation with a minimal footprint. Our CMPC Series fans continue this legacy, providing precision air cooling exactly where you need it—freeing up valuable floor space and helping improve air quality in your facility.


Key Features & Benefits

  • Direct Drive, Maintenance-Free Operation
    Eliminate the hassles that come with belt drives. The CMPC Series’ direct drive design ensures peak performance, minimal upkeep, and maximum efficiency—perfect for industrial applications focused on both productivity and improving air quality.
  • Fully Adjustable Airflow
    Tilt up or down 90° and swivel 360° to direct airflow with precision air cooling in mind. A positive tilt lock knob keeps the fan fixed in place, allowing you to precisely control air movement in any setting.
  • Multiple Sizes & Voltages
    Available in 36”, 42”, and 48” blade sizes to suit your space. Standard motor horsepower options include 1/2 HP and 1 HP for added flexibility. You can choose from 115V or 230V (1-phase) and 230V or 460V (3-phase) configurations—perfect for any industrial or commercial power setup. Additional voltages are available upon request.
  • Choice of motor enclosure
    Select from open drip proof (ODP) or totally enclosed (TE) motors to match your environment. ODP motors are ideal for typical indoor settings, allowing air to flow freely around the motor for cooling. TE motors, on the other hand, provide extra protection by sealing out dust and moisture—an excellent option for harsher or more demanding industrial applications.
  • Space-Saving Design
    Mount it to your ceiling or beam—our CMPC Series is a ceiling mounted fan that frees up floor space for equipment, foot traffic, or storage.
  • Ships Fully Assembled and Factory-Tested
    Every fan is fully assembled and tested prior to leaving our factory, minimizing downtime and installation headaches so you can optimize your airflow faster.
  • OSHA-Compliant Guards
    Robust safety guards keep workers protected while maintaining optimal airflow, meeting regulatory standards in industrial and commercial environments.
