Greenwood Airvac dMEV fan has host of features

Greenwood Airvac’s Unity CV2GIP dMEV fan achieves a specific fan performance of 0.16 W/l/s at its best point. The boost and trickle speeds of these fans can be accurately altered following testing to ensure compliance first time — unlike switching between preset airflow rates, which may not result in the exact airflow required.
These fans have eight patents and registered designs, including a twist-lock front fascia for easy installation and Greenwood CommissionSmart touch pad for quick and accurate push-button set up and commissioning.
Operation can be humidity and time controlled.
