An elegant solution for metal applications where a lower height profile is required compared to classic circular ducts is the OVAL jet metal duct.
- HEIGHT SAVINGS The exclusive oval shape allows for up to 50% space savings compared to circular ducts.
- EASE OF INSTALLATION The use of the new KLIMA-PLUG® snap-in system allows for great ease and speed of installation.
- AESTHETIC SOLUTION The diffuser is pleasant, modern, and easily integrable into any structure.















The distinctive oval shape of the OVAL Jet integrates perfectly into complex architectural contexts, replacing traditional circular diffusers with a refined profile. Made of metal with a height from 200 to 500mm and a length from 400 to 1000mm. It can be painted in all RAL chart colors.

The new OVAL section is available in various metals:
- galvanized;
- painted, pre-painted (in any color of the RAL classic scale);
- stainless, in INOX AISI 430, AISI 304, AISI 316.
- laminated steel
- aluminum
Regarding air distribution, the diffusion will always be determined by an appropriate number of rows of holes calculated in relation to the air flow rate of the ventilation unit, the available pressure at the diffuser inlet, specific architectural requirements, and customer requests.
Oval ducts are supplied in modules of 1.25 meters in length, with an innovative NIPPLO connection.
The edges are appropriately shaped to facilitate insertion and ensure the release of material stresses. Each module is supplied as standard with a clamp for ceiling mounting, complete with M8 female nuts for screwing threaded rods or other attachment systems.

Installation with Nipplo system developed by Klimagiel
Klimagiel has developed an innovative fastening system for oval ducts, designed to ensure faster, simpler, and safer assembly.
The Nipplo system involves each duct module being made with a female entry end, while the Nipplo acts as the male joining element. This allows two duct sections to be securely joined, resulting in a more stable and rigid structure, minimizing installation time and improving overall work quality.
Thanks to this method, assembly becomes more efficient, optimizing installation times and ensuring long-lasting system durability.
