It features metal construction (powder-coated steel body with aluminum components), automatic louvers, and a detachable steel mesh screen. Typical applications include greenhouses, garages, sheds, workshops, and attics where reliable air exchange is required. The unit measures roughly 480 × 480 × 215 mm and includes a 1.8 m power cord and control hardware in the box.
