SINCE 1948.

Economical belt-drive design
The RV Series provides dependable intake airflow at a cost-effective price point. A built-in, spring-tensioned motor mount and extra-long V-belts extend belt life while minimizing maintenance requirements.

Durable welded construction
Built with an all-welded steel housing and finished in a polyester powder coat, these supply fans are engineered for long-term service and resistance to demanding conditions.

Quiet, low-speed blades
Deep-pitched blades are designed to move high volumes of fresh outside air while operating at lower speeds, helping maintain a quieter working environment.

Vibration-reducing bearings
Rubber-isolated fan bearings cut down on vibration and mechanical noise, delivering smoother, more consistent operation.

Rolled inlet venturi
Each RV Series fan includes a rolled venturi that increases airflow efficiency and reduces turbulence, ensuring optimal supply performance.

Serviced from inside the building
Belts, pulleys, and motors can be accessed from the interior, simplifying maintenance and reducing the need for outdoor lifts or roof access.

Factory-assembled and tested
Every RV Series fan is fully assembled and factory-tested prior to shipping, ensuring quick installation and dependable operation from the start.

Triangle Engineering offers a full line of accessories to complement RV Series wall intake 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
  Protect the fan opening from exterior elements, helping maintain airflow performance while keeping equipment dry.
• Guards
  Provide a safety barrier around moving parts to protect personnel and equipment. OSHA requires guarding if any part of the fan is mounted within 7 feet of floor level.
• Shutters/Dampers
  Available in standard sizes to pair with each fan. Shutters regulate incoming airflow, reduce backdraft, and help maintain proper building pressure when the fan is not operating.

• Factories & light manufacturing – supply fresh air to balance exhaust systems, improving air quality and maintaining worker comfort.

• Warehouses & distribution centers – bring in cooler outdoor air to stabilize interior temperatures and reduce heat buildup.

• Gymnasiums & recreational facilities – deliver fresh air to replace humid or stale indoor air during peak activity.

• Workshops & maintenance facilities – provide a steady source of clean air to dilute fumes, dust, and odors.

• Agricultural & equipment buildings – draw in outside air to ventilate barns, sheds, or machinery storage areas.

• Commercial buildings – help schools, garages, and other facilities maintain balanced airflow by introducing outdoor air into large spaces.

Economical performance
The RV Series delivers reliable supply airflow at an economical price point, making it a smart solution for facilities that need dependable intake ventilation 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 RV Series continues that legacy with durable, cost-effective supply fans.

Built to last
Featuring all-welded steel construction and a durable polyester powder coat finish, these fans are engineered for long service life in commercial and light industrial environments.

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

Quiet, efficient operation
Deep-pitched blades and a rolled venturi design draw in high volumes of fresh outside air with minimal noise and turbulence.

Ships assembled & tested
Every RV Series fan ships fully assembled and factory-tested, ensuring quick installation and reliable performance from day one.

Balanced airflow with exhaust fans
For optimal indoor air quality, pair your RV Series intake fan with a Triangle Engineering exhaust fan. This balanced system helps maintain proper building pressure by replacing stale or contaminated air with fresh outside air.
