The PET/PETI is a ceiling-mounted supply and extract air diffuser designed for comfort ventilation in various settings, including offices, schools, retail stores, hospitals, and restaurants. The diffuser feature a perforated front panel and a back section with a circular air connection equipped with a rubber gasket. The standard PET/PETI diffusers provide a 4-way air distribution pattern, which can be modified to 1-, 2-, or 3-way distribution by placing deflector plates on the inner side of the front panel. These variations need to be specified when ordering using the corresponding codes: 1v, 2v, 3v, or 4v.
The difference between the PET and PETI is that the outer dimensions of the PET type vary with connection sizes, while the PETI maintains a consistent external dimension of 595x595 mm across all sizes.
The PET/PETI diffusers are ideal for ventilating comfort rooms where draught-free operation at low noise levels is important, such as offices, schools, retail stores, hospitals, and restaurants. For cooling applications, the recommended maximum temperature difference between the room air and the supply air is -10°C.
