Transcription

1 Supply air diffuser for ceilings PET PETI The TR connection box is an optional accessory for PET and PETI. Description The square perforated ceiling diffuser is best suitable for cofort ventilation. The unit consists of a perforated front panel and back box with a circular air connection. Correctly diensioned operates with a draught-free air distribution, at a low noise level, without the accuulation of dirt around the diffuser. The eleent is optial for offices, schools, departent stores or hospital applications, and ay also function as an exhaust air diffuser. The unit can be ounted into standard odular suspended ceilings, or freely suspended. If not otherwise specified is delivered with a standard -way air distribution setting. Recoended ax. t: - C. The PETI type is designed to fit standard odular suspended ceilings. Its perforance data are identical to the perforances of the PET units, but the external size of each forat is equal to the size of the standard (9x9 ) suspended ceiling plate. Serial sizes PET: 1,, PETI: 1,,,, 1, 0 irflow rates /h (1- l/s), See the diagras below for further inforation.

2 Material PET: The front perforated panel and the back connection box is ade of steel sheet. The frae is ade of aluinu. The unit is powder coated in R 900 white colour, with a rubber gasket on the air connection. PETI: The front perforated panel, the back connection box and the frae is ade of steel sheet, powder coated in R 900 white colour, with a rubber gasket on the air connection. Optional accessories P air deflector plate: s standard PET and PETI are always supplied with a -way air distribution. If ordered with the optional P air deflector plates, which are placed on the inside of the perforated front diffuser panel, the air direction pattern ay be odified to either 1, or -way. TR coissioning box: The TR standard coissiong box is priarily suitable for ounting and regulating supply air diffusers in a ceiling installation. The TR plenu box is recoended for applications, where there is a requireent for a low noise level perforance. TR coissioning box aterials: Galvanized sheet steel, sound-reducing glass-wool lainated glass fibre insulation. TK coissioning box: s an option PET and PETI is also available with TK, a connection box which has a reovable coissioning with easureent tubes for the exact calculation of the airflow. This feature siplifies the controlling and coissioning of the airflow at any tie. TK also includes internal sound insulation with optial sound attenuation qualities. TK is priarily suitable for ounting and regulating supply air diffusers in a ceiling installation. The coissioning box is recoended for applications where a low installation height is required. TK is available with 1- or -step diension change between the air duct and the diffuser box connection. For further inforation about TK please contact irvent. Mounting Both the PET and the PETI are connecting directly to the TR box. The diffusor front plate can easily be opened with the use of a plastic card, and reoved enabling a quick installation and cleaning. 1.. The front diffuser plate design is only an illustration.
