AprilAire says its 120-cfm V22BEC Energy Recovery Ventilator can help contractors meet code requirements for ventilation airflow and efficiency. The unit has a push-button fan-speed control for continuous operation; when paired with the manufacturer’s thermostats or 8120X digital controller, the ERV can be intermittently turned off when outdoor humidity or temperature is too high. A templated mounting bracket is included to simplify installation on ceilings, walls, or floors. aprilaire.com
