Triangle Fans 30" RVI Belt Drive Heavy Duty Industrial Supply Fan, 3/4 HP 115/230V 1 Phase, Totally Enclosed Motor

OVERVIEW

The Triangle Engineering RVI Series is purpose-built for wall-mounted intake ventilation, supplying large volumes of fresh outdoor air into industrial and commercial facilities. Designed to pressurize interior spaces and balance exhaust systems, the RVI Series improves air quality, temperature, and comfort in demanding environments such as factories, warehouses, data centers, and gymnasiums.

Each RVI fan features a heavy-duty galvanized wall box with a bronze powder-coated rolled inlet venturi, providing superior corrosion protection and smooth airflow. The belt-drive system delivers efficient, quiet operation while allowing in-building servicing — belts, motors, and pulleys can all be accessed from inside the facility for faster, safer maintenance.

Models equipped with Open Drip Proof or Totally Enclosed motors up to 1.5 HP include Triangle’s automatic belt tensioner, extending belt life and minimizing upkeep. Fans are available from 24” to 60” blade diameters and 1/3 to 5 horsepower, supporting single-phase, three-phase, and Hazardous Location motor configurations.

Key Features

• Durable construction: Heavy-gauge galvanized or welded steel wall housing combined with a powder-coated venturi for corrosion and wear resistance.
• Multiple sizes and power options: A wide selection of blade diameters from 24" to 60" and motor sizes ranging from 1/3 HP to 5 HP to meet airflow needs from approximately 4,000 to over 40,000 CFM.
• Reliable belt-drive systems: Belt-drive models include automatic or exclusive X-Wing belt tensioners for units up to 1.5 HP, which reduce maintenance and extend belt and motor life.
• Efficient venturi design: Rolled-inlet venturi engineered to reduce turbulence and improve airflow volume and overall efficiency.
• Flexible motor configurations: Available in single-phase, three-phase, and hazardous location models to meet a variety of industrial power and classification requirements.
• Factory-tested and ready to install: Units arrive fully assembled and factory-tested for faster installation and dependable performance straight out of the box.
• Service-friendly layout: All belt, pulley, and motor components are accessible from inside the building, minimizing downtime and simplifying routine maintenance.

Reliable, Efficient, and Built to Last

The RVI Series supply fans are built with heavy-duty construction designed to stand up to industrial mounting and continuous use. The fan housing features heavy-gauge, all-welded steel or rugged galvanized wall boxes for strength and corrosion resistance. The intake venturi is powder-coated (bronze or polyester finish) to protect against wear, weather, and airflow erosion. Precision-formed intake blades paired with a rolled-inlet venturi allow efficient airflow while minimizing turbulence. The drive system (belt or direct-drive, depending on model) uses industrial-rated motors, heavy-duty bearings and maintenance-friendly components (such as adjustable belt tensioners) so the fan delivers reliable performance for years, even under heavy-duty or harsh conditions. Overall, the RVI Series is engineered not just for airflow—but for long-term durability, low maintenance, and resilience in demanding industrial or commercial environments.
