ERV | O-Series Introduction

“O” Series energy recovery ventilators are designed for outside use in rooftop or “pad” installations where the application requires a “over and under” duct system. One of the benefits of this design is the ability to be ducted directly to the back of a rooftop air conditioning unit. Another use is for “through the wall” applications. The horizontal return duct connection can be converted to bottom return in the field. Field supplied balancing dampers should be utilized to help control the air volumes.
