Rectangular Roof Stack Unit NVR

The Price rectangular natural ventilator, model NVR, is a ceiling mounted unit which is designed to relieve air to the outdoors in cooling mode and exchange air with the outdoors in heating mode. The NVR features an integral fan which serves to draw air through the roof opening when a “boost” is required in cooling mode, as well as disrupt cool air motion in heating mode, thereby reducing the risk of draft. A wide variety of grille finishes and constructions are available to assist in blending in with the aesthetic of the occupied space.

Available with either a penthouse louver or a mushroom vent, the NVR offers a packaged solution to simplify the selection and design of natural ventilation systems.
