5 Execution and function, material, product code Execution and function ROKA, RPKA is a ceiling air diffuser with good technical characteristics and has the same technical data regardless of which appearance is selected. Diffusion directions and throw can be changed easily. The air diffuser is supplied with a separate diffuser plate and transfer box. The measurement hose from the measurement damper in the ATTB connection box is very easily accessible inside the diffuser. This facilitates measurement and balancing. Connection box ATTB has a combined measurement and balancing damper with low noise generation, which is easily removable without changing the settings. The connection box is available in two executions, insulated and uninsulated. The connection box can be connected directly to a duct bend, but different k-factors are applicable for different installation alternatives. Material and surface finish Both the diffuser, including the connection piece, and the connection box are made from hot-dip galvanized sheet. The devices are powder-coated for a high surface finish and good impact and scratch resistance. Standard colour RAL-90, gloss, equivalent to white NCS S 02-Y. Other colours on request. Installation, adjustment and maintenance Instructions for installation, balancing and care are described in detail in our technical instructions, which are supplied with every product.
