Greenhouse Exhaust Shutter, Manual, 18" x 18", Aluminum, Single Panel

Aluminum exhaust shutters are a fundamental piece of any comprehensive ventilation strategy, designed to ensure fresh air is properly brought into your structure for mixing and circulation. This 18" x 18" model is constructed from heavy-duty aluminum and features reinforced welded corners, making it one of the best-valued options for greenhouse growers today. By coordinating with exhaust fans, these shutters help facilitate the vital exchange of air needed to keep your growing environment healthy and productive.

The engineering of this shutter focuses on both efficiency and weather protection. It utilizes interlocking louvers that create a tight seal against the elements when closed, helping you maintain a controlled climate within your greenhouse. To ensure consistent operation without sticking, the unit is built with nylon bearings and solid shafts. Furthermore, a dedicated tie bar is included to eliminate the common issue of shutter flapping, ensuring quiet and stable performance during operation.

Installing this manual shutter is straightforward, as the frame is delivered with pre-drilled mounting holes to minimize setup time. For those looking to automate their greenhouse environment, this unit is fully compatible with motorized shutter kits, allowing you to easily transform it into a power shutter at a later date. To maintain peak efficiency and air movement, it is recommended that the louvers be cleaned periodically to remove any accumulated debris.
