5 ROKA, RPKA Supply air diffuser 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.

6 VSKA Swirl diffuser Swirl diffuser VSKA VSKA are supply air diffusers designed for ceiling mounting. The design of the air deflectors and discharge outlets causes the air discharged by the diffuser to mix with the air in the premises (high induction rate). This provides an excellent indoor climate, even when the temperature of the supply air is appreciably below the room air temperature. VSKA has adjustable air deflectors. The diffusers are shown without, with insulated and uninsulated connection box. VSKA has an adjustable slot of mm.

20 DYKB, DYCB Nozzle air diffuser Execution and function, material, product code Execution and function DYKB and DYCB are air diffusers with adjustable nozzles for the setting of an optional diffusion pattern, intended for ceiling mounting. The design of the nozzles gives very good mixing of the room air (high induction). The nozzles are rotatable and offer the possibility of changing the diffusion pattern and the diffusion direction for adaptation to the actual installation and device position. The possibility of optimal air flow is assured in this way, and large undertemperatures can be handled. DYKB and DYCB adjustable slot of mm for greater air flows. Both the devices are square; DYCB has a circular, and DYKB has a square nozzle pattern. 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.

56 DYSB Nozzle air diffuser Execution and function, material, product code Execution and function DYSB is a series of nozzle air diffusers with adjustable nozzles for the setting of an optional diffusion pattern, intended for ceiling mounting. The design of the nozzles gives very good mixing of the room air (high induction). The nozzles are rotatable and offer the possibility of changing the diffusion pattern and the diffusion direction for adaptation to the actual installation and diffuser position. The possibility of optimal air distribution is assured in this way, and large undertemperatures can be handled. The devices are shown both with insulated and uninsulated connection box ATTB. The measurement damper can be removed from room without changing the flow setting, for inspection and cleaning of the damper, the box and the duct. The connection box is approved for cleaning. The measurement hose from the measurement damper in the ATTB connection box is very easily accessible inside the diffuser. This facilitates measurement and balancing. The connection box can be connected directly to a duct bend but different k-factors are applicable for different installation alternatives. The nozzle diffuser is supplied with a separate diffuser plate and transfer box. Material and surface finish Both the diffuser and the connection box are made from hot-dip galvanized steel sheet. The diffusers are powder-coated for a high surface finish and good impact and scratch resistance. Standard colour White RAL-90, gloss, equivalent to NCS S 02-Y. Other colours on request.

65 Floormaster DVRA, round Floormaster DVRA, Round terminals Floormaster DVRA are round supply air terminals for positioning on the floor with a connection to a circular duct. The terminal is designed for displacement air handling in accordance with the Floormaster system for good air comfort and high ventilation efficiency. Floormaster terminal devices are equipped with an air distribution system consisting of a roll-shaped perforated distribution plate with an attached honeycomb sheet in black polycarbonate. This component combination permits uniformly horizontal air distribution through the front panel with a short near zone and a very low noise level.
