BI-FLOW® Shutter
- Improves fan performance by minimizing obstructions during fan operation.
- Delivers up to 10% more air with 75% less opportunity for air to leak through compared to a traditional louver shutter.
- BI-FLOW Doors do not suffer the 12-15% loss of efficiency and air speed typical of dirty louver-style shutters, so air speed is maintained over time.
- The BI-FLOW Shutter consists of only two moving parts for greater reliability and easier cleaning.
ProTerra® Louver Shutter
- Belled shutter has a curved, aerodynamic frame with flexible louver edges to help seal the fan’s opening.
- Corrosion-proof vinyl construction with a rigid vinyl frame and fiberglass rod louver hinges.
- Idler Tensioner Maintains Belt Tension
- Louvers are easy to replace and have a smooth, easy- care finish for low maintenance.
