Non-return valve with folding slat (very light so very little resistance) that open when there is air displacement by a fan. They ensure that the air flows in one direction only, but at the same time do not adversely affect fan capacity in a significant way. This valve can be installed in a spiro tube or plastic channel (valve is slightly smaller in diameter so it can be slid into the tube and then has to be fixed with glue/sealant or tape). Application: This non-return valve can be installed behind ventilators that can not bridge much resistance, so the valve is suitable for various bathroom fans.
