neverest RKI backflow flap is very robust and durable. The backflow flap opens and closes automatically. The strong stainless steel spring allows installation horizontally or vertically. Perfect for retrofitting ventilation systems without backflow flap. The rubber ring ensures a 100% seal and quiet closing when the exhaust fan is not in operation. Function: The exhaust air backflow valve can be used universally in all standard round ventilation pipes and flex pipes according to DIN EN 1506. The backflow flap prevents the return of the exhaust air or the entry of cold outdoor air. The flaps open when the fan turns the exhaust air outwards and close automatically as soon as the airflow stops. Versatile for use in all supply air and exhaust systems, such as air conditioners, dryers, cooker hood, dryers, heating systems, and ventilation systems in private homes, commercial, and industrial settings. Perfect choice for hobbyists and professionals. The backflow flap is very stable, temperature-resistant and reliable. Installation is simple, just slide in the ventilation pipes and enjoy the benefits. We are subject matter experts and there for you. If you have any questions or complaints, please contact our customer service directly. Your request will be processed immediately.
