The perforated metal ducts combine the characteristics of uniform distribution and high induction, the incombustibility and a particularly high aesthetic result. They can also be used for air aspiration and they are easily installed by means of the collar joints.
The metal ducts may have circular or semicircular shape.
The metal diffusers are provided of rows of microholes that allow launching the air in the directions and at the speed desired, so they can be used even in case of high installation elevations, for both heating and cooling, as in the case of traditional ducts.
The perforated metal diffusers are made of following materials:
- Galvanized steel
- Painted steel in the colours of the RAL matching system
- Stainless steel AISI 304
The collars that joints the different sections of diffuser also have the function of connecting to supports and make the installation easy and fast.
