Wind-Driven Roof-Mount Exhaust Fans
Designed to spin freely with the slightest breeze, these fans create a vacuum that draws air out from buildings and ventilation systems—no electricity required. They are also known as turbine ventilators. Mount fans on your roof away from wind obstructions.
Optional mounting bases are sold separately.
All bases have a square bottom, round top, and flashing to simplify installation.
To Order: For slope bases, please specify pitch: 1/12-11/12 in increments of 1/12. To determine pitch, use an angle indicator or divide rise by run (see illustration). For instance, if your roof rises 5" in 12" of horizontal space, your pitch is 5/12.
Fan-Cooled Compressed Air Aftercoolers
These aftercoolers have a fan that chills hot air coming from a compressor. Cooling the air condenses water for removal from your compressed air system. Install a separator (not included) after your aftercooler to collect and discharge water.
