LINN Gerätebau has been involved in equipping fish farms throughout Europe for 40 years. Based on the experience of our own trout farm, which has been run by the Linn family since 1929, we have repeatedly developed equipment for everyday use, which has become established on the market and then often becomes part of the necessary technical standard in fish farms.

We are the market leader in Europe in the field of water aeration and oxygen-enrichment of fish farms and aquaculture. The main focus here is on floating water aerators, which bring the oxygen, which is essential for the fish, into the water. More than 10 different types of devices with different ejection patterns and motor power are manufactured in our company - often individually according to customer requirements.
