This 40\" x 40\" model is constructed from \u003cstrong\u003eheavy-duty extruded aluminum with reinforced welded corners\u003c\/strong\u003e, offering a durable and cost-effective solution for large-scale air exchange. The double-panel configuration provides the necessary stability for larger wall openings while maintaining an affordable cost for professional growers.\u003c\/p\u003e\n\u003cp\u003eThe engineering of this shutter focuses on quiet efficiency and weather protection. To prevent noise and wear, a dedicated tie bar is included to eliminate louver flapping during high-velocity air movement. The use of solid shafts paired with nylon bushings ensures that the mechanism operates smoothly without sticking, while the \u003cstrong\u003einterlocking louvers\u003c\/strong\u003e create a protective seal to keep out wind and rain when the ventilation system is idle.\u003c\/p\u003e\n\u003cp\u003eInstallation is streamlined by the inclusion of pre-drilled mounting holes in the frame, significantly reducing setup time. Although this is a \u003cstrong\u003emanual unit\u003c\/strong\u003e, it is \u003cstrong\u003efully compatible with motorized shutter kits\u003c\/strong\u003e, allowing for easy conversion to an automated power system in the future. To ensure the unit continues to move air with maximum efficiency, it is recommended that the louvers be periodically cleaned of any accumulated debris. This versatile shutter is suitable for a wide range of environments beyond greenhouses, including industrial, dairy, and poultry facilities.\u003c\/p\u003e\n\u003ch3\u003eOther Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Type: \u003c\/strong\u003eDouble-panel design for enhanced structural performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual Inlet Size:\u003c\/strong\u003e 40\" x 40\" (excluding the mounting flange).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Industry Application:\u003c\/strong\u003e Optimized for use in swine, dairy, industrial, and poultry houses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomation Compatibility: \u003c\/strong\u003eCan be upgraded to a power shutter using a separate motor kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance: \u003c\/strong\u003eSimple, periodic cleaning of the louvers maintains peak airflow efficiency.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"J\u0026D Manufacturing","offers":[{"title":"Default Title","offer_id":61546644504946,"sku":"VRSG40A-C","price":203.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0069\/5854\/6980\/files\/Aluminum-Shutter_Open_1800x1800_579301b2-4a2c-462f-85ec-76a1935fa9d6.png?v=1769215532","url":"https:\/\/plantagreenhouses.com\/products\/greenhouse-exhaust-shutter-manual-40-x-40-aluminum-single-panel","provider":"Planta Greenhouses","version":"1.0","type":"link"}
