Description

PET/PETI is a square diffuser for suspended ceiling application, suitable for supply and extract air, too. The unit consists of a perforated front panel and back box with a circular air connection with rubber gasket. The standard PET/PETI diffusers have a 4 way air distribution pattern. However, this can be changed to 1-, 2- or 3-way air distribution by placing a deflector on the inner side of the front. When ordering, these need to be differentiated by using the corresponding codes: 1v, 2v, 3v, or 4v.

The PETI type is designed to fit standard modular suspended ceilings. Its performance data are identical to the performances of the PET units, but the external size of each format is equal to the size of the standard (595x595 mm) suspended ceiling plate, so the PETI can be easily installed into the suspended ceiling.

Application

The diffuser is suitable for the ventilation of comfort rooms, offices, schools, department stores, hospitals, restaurants etc. where draught-free operation at low noise level is important. In case of cooling, the recommended maximum difference between the temperature of the room air and that of the supply air is 10 °C.
