Economical belt-drive design
The V Series delivers reliable exhaust performance at an economical price point. A built-in, spring-tensioned motor mount and extra-long V-belts ensure extended belt life while minimizing maintenance requirements.

Durable welded construction
Each fan is built with an all-welded steel construction and finished with a tough polyester powder coat. This rugged design provides strength, stability, and corrosion resistance for long service life in demanding industrial environments.

Quiet, low-speed blades
Deep-pitched, low-speed blades move high volumes of air while maintaining quiet operation—ideal for applications where both performance and noise reduction are important.

Vibration-reducing bearings
Rubber-isolated fan bearings reduce vibration and mechanical noise, contributing to smoother, more dependable operation.

Rolled inlet venturi
Each V Series fan incorporates a rolled venturi design that improves airflow efficiency and reduces turbulence. Combined with the low-speed blade profile, this enhances performance while keeping operation smooth and quiet.

Factory-assembled and tested
All V Series fans are shipped fully assembled and factory-tested, ensuring they are ready for immediate installation and dependable performance from day one.

Triangle Engineering offers a full line of accessories to complement V Series wall exhaust fans, ensuring an optimal installation for your unique application. The following optional add-ons can be tailored to meet your environmental and operational needs:

• Rainhoods
  Provide a protective cover against exterior elements, keeping critical fan components dry.
• Guards
  Add a protective barrier to safeguard personnel and equipment by enclosing moving parts. OSHA requires guarding if any part of the fan is mounted within 7 feet of floor level.
• Shutters/Dampers
  Offered in standard sizes or custom increments (as small as 1/8″) to fit your exact opening. They regulate airflow, limit backdraft, keep rain out when fan is turned off and maintain optimal building pressure when the fan is off.

• Factories & light manufacturing – provide general exhaust ventilation to remove heat, dust, and stale air, keeping work environments more comfortable and productive.

• Warehouses & storage facilities – help control air quality and temperature by exhausting warm or stagnant air in large, open spaces.

• Gymnasiums & recreation centers – support a healthier environment by exhausting humid, warm air created during high activity levels.

• Agricultural & equipment buildings – suitable for barns, machine sheds, and other utility structures needing cost-effective air movement.

• Loading docks & workshops – improve air circulation in spaces where fumes, heat, or odors can build up.

• General commercial ventilation – an economical solution for schools, garages, and other buildings that require reliable wall-mounted exhaust.

Economical performance
The V Series provides reliable exhaust ventilation at a lower upfront cost, making it an ideal choice for facilities that need dependable airflow without overspending.

Made in the USA
Built in the USA with a blend of domestic and foreign components, Triangle Engineering has been a trusted name in industrial ventilation since 1948. The V Series continues that legacy of value and performance.

Built to last
All-welded steel construction with a durable polyester powder coat finish ensures long service life in commercial and light industrial environments.

Reduced maintenance
A spring-tensioned motor mount and extra-long V-belts extend belt life, while rubber-isolated fan bearings help reduce vibration for smoother, quieter operation.

Quiet, efficient operation
Deep-pitched, low-speed blades paired with a rolled venturi design move large volumes of air with minimal noise and turbulence.

Ships assembled & tested
Every V Series exhaust fan ships fully assembled and factory-tested, so installation is straightforward and performance is ready from day one.

Balanced airflow with supply fans
For optimal ventilation and indoor air quality, pair your V Series exhaust fan with a Triangle Engineering supply fan. This balanced system replaces exhausted air with fresh intake air, maintaining proper building pressure and a healthier environment.
