The Go-To Ceiling Mounted Fan for Precision Air Movement

For over seven decades, Triangle Engineering has led the way in compact, high-efficiency ceiling mounted fan systems. The CMB Series continues that tradition with a quieter belt drive configuration designed to minimize operational noise while providing targeted air circulation—keeping both your energy costs and noise levels in check. By reducing reliance on personal fans and floor space, these belt-driven units help maintain a cleaner, more productive environment without compromising their ability to free up valuable floor space and improve air quality throughout your facility.

Key Features & Benefits

• Quiet belt drive performance: The CMB Series’ belt drive design ensures quieter operation compared to direct drive systems, making it ideal for noise-sensitive facilities while still delivering powerful air movement. Models with open drip proof (ODP) or totally enclosed (TE) motors include an automatic belt tensioner for simplified maintenance.
• 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 and voltages: Available in 36″, 42″, and 48″ blade sizes to suit your space. Standard motor horsepower options include 1/2 hp, 3/4 hp and 1 hp for added flexibility. You can choose from 115V or 230V (single-phase) and 230V or 460V (three-phase) configurations—perfect for any industrial or commercial power setup. Additional voltages are available upon request.
• Expanded motor options: Select from open drip proof (ODP), totally enclosed (TE), or hazardous location (HL) motors to meet specific environmental requirements. ODP and TE models come with an automatic belt tensioner, while HL motors are designed for use in areas where flammable or combustible materials may be present.
• Space-saving design: Mount it to your ceiling or beam—our CMB 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.

• Event halls and large venues: Circulate air effectively to keep guests comfortable without cluttering the floor plan.

Why CMB Series?

1. Reliability and durability: Built in the USA with a blend of domestic and foreign components, the CMB Series is designed to provide long-lasting, high-performance ventilation—even in the harshest industrial conditions.
2. Space optimization: As a ceiling mounted fan, the CMB Series frees up floor space for equipment, storage, or walkways—an ideal solution for busy facilities where every square foot matters.
3. User-friendly design: A quick, painless installation process means you can have improved airflow almost immediately—no need for complex assembly or specialized installers.
4. Reduced noise: Quieter belt drive operation helps minimize distractions, making the CMB Series ideal for noise-sensitive environments.
5. Enhanced workplace harmony: Overhead mounting ensures broad coverage throughout the workspace, eliminating the need for multiple floor fans and the “fan wars” they can cause. The result is a more cohesive, comfortable environment that supports employee morale and productivity.
