RRA

• The RRA is available in 18 diameters from 160 mm to 900 mm.

Depending on the air volume to be conveyed and the desired appearance, the circular pipe adapts to any room situation.

The number of slots can be freely selected depending on the desired diameter.

Starting with one slit in a discreet look up to 14 slits, everything is possible.

An air volume of 125 m³/h can be blown into the room per meter of slot.

The length of the tubes can be adjusted to the millimeter up to a maximum length of 2000 mm.

The slot length is automatically adjusted to the pipe length.

• The air jet direction can be adjusted steplessly between 0° and 180° during operation using the eccentric roller.
• Depending on the roller position, any blast direction can be set with a constant air volume flow or variable volumetric flows with a constant blast direction.
• The negative pressure ensures a stable flow and precise jet control with low sound power levels.
• A high induction already takes place in the area of the exit plane of the slot.
• Rectifier profiles ensure that the outlet speeds are uniform over the length of the roller and perpendicular to the roller.

• The design of diffusers is based on the required air volume in accordance with DIN EN 16798.
• The Kampmann calculation programs can be used to design the diffusers for specific projects.

• The round tube section is mounted using threaded rods or wire rope hangers.

The free round duct tool can be used to quickly and easily design and hydraulically calculate the entire duct run. This ensures that the desired air volume is supplied to the room from each diffuser.

The number of slots is freely selectable depending on the diameter and can be selected with up to 14 slots (RRA) or 36 slots (ORA).
