Kingfisher protection

Our heraldic animal: the kingfisher. Where he feels comfortable, the waters are still fine. We have a lot in common with the kingfisher: its distinctive, multi-colored, iridescent plumage is a symbol for a variety of products that only we can offer you. Its incomparably fast wing beats and maneuverability stand for fast delivery and a high level of mobility that you as a customer can expect from your Winkler team.

Last but not least, the kingfisher is considered an endangered species that is under strict nature protection in Germany. On this issue too, we feel very connected to the flying gem, as the people like to call it. Because Winkler Filtertechnik is in close competition with much larger market participants. Being ahead of them - namely being able to respond more quickly and flexibly to customer inquiries - is something we enjoy every day.
