Efficient drying, cleaning, blowing off,
heating & cooling!

In contrast to the competition, where mostly piston compressors and jet nozzles are used, we work exclusively with compact, high-speed turbo fans, which generate a constant, laminar air flow or air curtain in a particularly efficient manner (efficiency >70%) in conjunction with specially designed nozzles.

The result is outstanding and has clear cost advantages compared to other technologies.
