Spiral ducts and the matching fittings from the HYDRA® product range for air-conditioning and ventilation facilities in buildings are manufactured according to the state of the art. The fittings can be installed with either an O-ring gasket or a lip seal.
They are manufactured from roll-galvanised sheet steel in a process that reduces the impact on the environment and offers outstanding corrosion protection.
The large variety of components and dimensions and a very well stocked warehouse ensure short delivery times.
