PVI SERIES – HEAVY-DUTY BELT-DRIVE PORTABLE BOX FANS
The PVI Series represents Triangle Engineering’s heavy-duty belt-driven portable box fans, engineered for high-volume airflow in free air applications. Designed with a rugged galvanized steel housing, OSHA-compliant guards, and a serviceable belt-drive assembly, PVI fans deliver reliable air movement for industrial and commercial environments.
Available in 36”, 42”, 48”, 54”, and 60” blade diameters, PVI models produce airflow from 10,800 to 43,500 CFM, with horsepower ratings ranging from 1/2 HP to 5 HP. Built for mobility and durability, the PVI Series is ideal for spot cooling, equipment cooling, and large-area air circulation where permanent installation is not required.
Constructed for longevity, the PVI Series features heavy-gauge galvanized construction, a rolled inlet venturi for improved airflow efficiency, and belt-driven performance designed for long-term serviceability.

PVI portable box fans are commonly used for:
- Industrial spot cooling
- Cooling manufacturing equipment and compressors
- Warehouse air circulation
- Loading dock airflow
- Rolling in front of large overhead doors for air exchange
- Temporary ventilation during maintenance operations
- Gymnasiums and large open commercial spaces
The PVI Series is designed to move large volumes of air in open environments. For exhausting buildings under static pressure, refer to Triangle’s wall-mounted exhaust fan lines.
PVI fans are engineered for customers who need industrial-grade airflow in a portable box fan configuration. The galvanized housing resists corrosion, the belt-drive assembly supports long-term serviceability, and OSHA-compliant guards enhance safety in active work environments.
With sizes up to 60” and airflow exceeding 43,000 CFM, the PVI Series delivers industrial-scale air circulation in a mobile format.
Every unit ships fully assembled and performance tested.
Built in the USA with a blend of domestic and global components, the PVI Series reflects Triangle Engineering’s commitment to durable, serviceable airflow solutions.
