The Go-To Belt-Drive Exhaust Fan with Integrated Shutter and Guard

Since 1948, Triangle Engineering has specialized in crafting dependable industrial ventilation solutions. Building on the success of our VI Series, the VIK Series packages the fan with both a VIG Series safety guard and IWS Series exhaust shutter, offering a complete, wall-mounted exhaust solution in one streamlined product. By removing hot, stale, or contaminated air, these belt-drive fans help improve indoor air quality while reducing downtime and maintenance costs.

Key Features & Benefits

1. Belt-drive performance
   The VIK Series utilizes a belt-drive system for reliable, efficient air movement. Choose from open drip proof (ODP), totally enclosed (TE), or hazardous location (HL) motors. On ODP or TE models up to 1.5 hp, an automatic belt tensioner is included.
2. Integrated shutter and guard
   Every VIK model arrives with a factory-installed IWS Series exhaust shutter and VIG Series safety guard, saving time on procurement and installation. The shutter prevents backdrafts while the guard protects personnel from moving parts.
3. Integrated galvanized wall box
   Each VIK package includes a factory-installed galvanized steel wall box for simple, secure mounting on any exterior wall. This feature streamlines installation and saves valuable time.
4. Robust wall-mounted design
   Engineered for exterior wall placement, these exhaust fans pull interior air out of your facility, creating negative pressure for improved ventilation.
5. Easy in-building servicing
   All belts, motors, and pulleys are accessible from inside, minimizing downtime and labor costs—no need for external lifts or complex procedures.
6. Multiple size and power options
   Blade diameters range from 24″ up to 60″. Motor horsepower spans 1/3 hp to 5 hp, so there’s a configuration for virtually any industrial exhaust requirement.
7. Rugged, industrial-grade construction
   Built from heavy-gauge materials to thrive in harsh industrial conditions, each assembly is carefully designed for long service life in demanding environments.
8. Ships fully assembled and tested
   Every fan package is shipped fully assembled—fan, shutter, guard, and wall box—and factory-tested to simplify on-site setup.

• Heavy Equipment & Foundry Operations: Protect personnel and equipment by exhausting high temperatures and metal fumes.
• Large Commercial Buildings: Improve overall indoor air quality by venting out accumulated heat and contaminants.

Optional Accessories

• Rainhoods: Provide additional weather protection on the exterior side of the wall box, helping shield the fan assembly from harsh conditions and prolong service life.

The Importance of Adequate Ventilation

Adequate ventilation is necessary for employee and building health. In addition, many building codes require adequate ventilation to ensure acceptable indoor air quality. ASHRAE Standard 62.2 provides guidelines for ventilation for indoor air quality.
