Koolair introduces two new grille models:
Circular egg crate grille with straight blades → 22-5-C, and with inclined blades → 22-5-I-C.
Model 22-5-C has been specifically designed for installation in plaster ceilings, offering an elegant and functional solution for air return applications. It features quick and easy mounting using downlight-type springs or screws, and allows direct connection to circular ducts or via plenum box.
Ideal for spaces requiring high air volumes, this grille combines performance with a discreet and refined design, integrating seamlessly into environments where aesthetics are as important as functionality.
Hinged square egg crate grille with straight blades → 22-6, and with inclined blades → 22-6-I.
Designed for installation in false ceilings, this solution enables fast and effective cleaning of the internal system, ensuring compliance with the most demanding hygiene standards.
Its hinged design allows tool-free maintenance, making it ideal for controlled environments such as laboratories, operating rooms, or pharmaceutical production areas.


Both models are intended for air return and offer the option of 45º inclined blades, enhancing both aesthetic and functional integration in various settings. However, they differ significantly in terms of mounting systems and available accessories.
Refer to the technical documentation for full details on these two new products.
