About this item
- neverest RKI check valve 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 100% closure and quiet closing when the exhaust fan is not in operation.
- Function: the exhaust air backflow flap is universally applicable in all standard round ventilation pipes and flex pipes according to DIN EN 1506. The backflow flap prevents the exhaust air from flowing back or the inflow of cold outside air. The flaps open when the fan blows the exhaust air outwards and closes automatically as soon as the airflow breaks off.
- Versatile 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 industry.
- Perfect choice for hobby craftsmen and professionals. The backflow flap is very stable, temperature-resistant and reliable. Installation is uncomplicated, simply slide into the ventilation pipe and enjoy the advantages.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
