The Extreme Series provides outstanding performance in a wide range of working environments.


The Exterior Grille protects the exhaust side of the system from weather elements when installed through an exterior wall. The external grille cover is highly recommended. Outside venting can be done if the outside temperature does not exceed 110°F.
