Micro-jet nozzles linear diffusers The KIS linear diffusers are designed to be applied in air conditioning ventilation and heating systems and at a temperature differential up to 12ºC. Micro-jet nozzles linear diffusers, giving complete flexibility of direction, suitable for wall or ceiling mounting. Diffuser constructed from aluminium and nozzles from PP. As the result of collaboration with the Lievore, Altherr & Molina studio, KIS diffuser provides a new look for this type of diffusers, with smoother lines, reducing the visual impact within the interior architectures.
