SINCE 1948.

• 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.

• Blade sizes: 36″, 42″, 48″
• Motor horsepower: 1/2 hp, 3/4 hp, or 1 hp
• Motor enclosure: open drip proof (ODP), totally enclosed (TE), or hazardous location (HL)
• Drive type: Belt drive, available in both single-phase and three-phase
• Automatic belt tensioner: included on ODP and TE models

• Mounting options: Ceiling mount (standard) or optional bracket for beam/column mount
• Construction: Built with industrial-grade components to withstand challenging environments

• Manufacturing and industrial facilities: Achieve precision air cooling at individual workstations while meeting air quality and safety requirements.
• Assembly lines: Provide targeted airflow along production lines, improving worker comfort, productivity, and heat/fume control.
• Warehouses and distribution centers: Circulate air efficiently to reduce energy costs and enhance air quality.
• Automotive and aerospace workshops: Maintain a safer, cleaner environment by dispersing fumes and directing airflow away from key work areas.
• Data centers and server rooms: Target specific hot zones to keep critical equipment cool.
• Gymnasiums and fitness centers: Eliminate stagnant air and maintain a fresher, more comfortable workout space.
• Event halls and large venues: Circulate air effectively to keep guests comfortable without cluttering the floor plan.

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.
