Fig. 4: Jet pattern of outlet installed flush with the ceiling
The radial slot outlet generates turbulent mixing air flow with highinduction radial air jets. As standard the preset bar position, i.e. discharge direction, is horizontal. Altering the bar position enables to adjust the discharge direction from horizontal to a downward incline. By closing several bar segments the discharge pattern may also be changed from full 4-way discharge to partial discharge. A key and instructions are available for subsequent bar adjustment. The radial slot outlet to be used as a return air inlet has its bars set to the vertical position as standard, but it can also be supplied with horizontal bars or without bars. Installation freely suspended from the ceiling In this case the outlet element is fitted with additional lateral slots. The additional air jets so obtained stabilize the whole supply air flow and raise the discharge flow, thus achieving large radial penetration depth into the room, even when cooling. The reduction of temperature and jet velocity is the same as for outlet installation flush with the ceiling.

Radial slot outlet RL-C
Construction design Preliminary remark
The circular-type radial slot outlet RL-C generates turbulent mixing air flow and is designed for air distribution in commercial applications. It is particularly suitable for spaces with high indoor air flow requirements and can be installed flush with the ceiling or freely suspended. The discharge direction can be adjusted by altering the position of several bars. This air outlet can also be used as a return air inlet.

Radial slot outlet RL-C
Adjustment of discharge direction Discharge direction and air volume flow rates
The radial slot outlet can discharge the supply air horizontally in 4, 3 or 2 directions. For 4-way discharge all bars are in the ‘h’ position. If air discharge is required only 3-way, 2-way symmetric, or 2-way asymmetric, then several slots are to be closed as shown below. The air volume flow rate is thus reduced; the related factors can be read off the following table.

Construction design
The RL-C outlet is available in 4 sizes. It is consists of of the circular faceplate 1 with built-in bars 1a that can be adjusted individually, and of the circular connection box 2. For installation freely suspended from the ceiling, the outlet element is fitted with additional lateral air slots 1b. As standard the lateral connection spigot 3 1) is fitted with a damper 4 adjustable from the room. The outlet element can be easily taken down after removing the central fastening 5. The RL-C outlet will be suspended at appropriate holes 6 (ø 9 mm) positioned in the upper part of the connection box, e.g. with customary quick fasteners.

Radial slot outlet RL-C
Mode of operation
Installation flush with the ceiling With such installation and horizontal air discharge the highturbulence air jets slide along the ceiling. The resulting flow achieves intensive admixture of indoor air concomitant with fast reduction of temperature and jet velocity.
