The Go-To Industrial Exhaust Fan for Maintenance-Friendly Ventilation

Building on our legacy of durable, high-performance ventilation systems, Triangle Engineering’s VID Series exhaust fans offer a direct drive design for reliable, low-maintenance airflow in wall-mounted applications. By drawing out heated or stale air, these fans help stabilize interior temperatures and reduce airborne contaminants—ideal for demanding industrial settings where downtime and maintenance costs must be kept to a minimum.

Key Features & Benefits

1. Direct drive operation
   The VID Series uses a direct drive system, eliminating belts and pulleys. This reduces maintenance needs, lowers downtime, and provides a more compact profile.
2. Robust wall-mounted design
   Engineered to mount on an exterior wall, these exhaust fans pull interior air out of your facility. The result is a negative pressure environment that improves air quality and controls heat.
3. Maintenance-Friendly Construction
   With no belts or tensioners to service, direct drive motors simplify upkeep and reduce the likelihood of mechanical failures. This design also means fewer parts to stock or replace.
4. Flexible motor & voltage options
   These fans are available in 1/2 hp or 1 hp, totally enclosed (TE) motors, with single-phase (115V or 230V) or three-phase (230V/460V). Single-phase models come standard with a cord and molded plug for quick and easy connection. Choose the power configuration that meets your facility requirements.
5. Integrated wall box
   Each VID model ships with a factory-installed wall box. Simplified installation helps you get up and running quickly.
6. Rolled inlet venturi
   A rolled inlet venturi finished in durable polyester powder coat boosts airflow efficiency while standing up to harsh industrial conditions.
7. Ships fully assembled & tested
   Every fan leaves our factory fully assembled and rigorously tested, saving you on-site labor and ensuring you can put it to work immediately.

Available Accessories

Triangle Engineering offers optional accessories to enhance installation and performance in various environments:

• Rainhoods
  Shield against weather and protect internal components from harsh outdoor conditions.
• Guards
  Enclose moving parts to protect both operators and equipment.
• Shutters/Dampers
  Offered in standard sizes or custom increments. They regulate airflow, minimize backdraft, and maintain consistent building pressure.
• Temperature Control (Optional)
  Available on single-phase models up to 1 hp. This integrated control automatically turns the fan on or off based on a user-defined temperature setpoint, ensuring efficient operation and a comfortable work environment.

Ideal Use Cases

• Manufacturing & Industrial Plants: Remove fumes, dust, and heat with minimal maintenance demands.
• Warehouses & Storage Facilities: Prevent hot, stagnant air while reducing upkeep compared to belt-driven fans.
• Food & Beverage Processing: Manage odor, humidity, and steam for safer working conditions.
• Automotive & Aerospace Workshops: Extract contaminants and moderate facility temperatures.
• Commercial Buildings & Retail: Vent out stale air to keep indoor environments fresh for customers and employees.

Why VID Series?

1. Lower Maintenance Costs
   The direct drive design means fewer moving parts and reduced wear, so your fans run smoothly with minimal service.
2. Improved Air Quality
   By drawing out heated or contaminated air, the VID Series helps create negative pressure that improves overall ventilation.
3. Easy Install
   Easily mounted on an exterior wall using the integrated wall box, this design simplifies installation and reduces install time.
4. Flexible Power & Control Options
   Choose single-phase or three-phase power to match site requirements. Opt for temperature control to automate fan operation based on your desired environment.
