Chimneys
Application: used for building ventilation air
Pros
- Effective on odor reduction, especially in areas less than 1000 feet from the building.
- Some designs may reduce dust emission.
Cons
- No reduction in emission occurs.
- Chimneys must be relatively tall to have a significant impact.
- Appearance of chimneys may make the building look “factory-like”.
