Round Duct Nozzle Jet Diffuser Type DSA-RR
Description
Fastening
In modern architecture, sheet metal and spiral ducts of air-conditioning systems are often incorporated in the design of the
room. Emphasis is often placed deliberately on parts of the supply system. In this visible installation of the ventilation ducts, it
is a good idea to integrate the air diffusers into the ducts.
The round duct nozzle jet diffuser type DSA-RR is suitable for
installation into supply air systems. The integrated nozzles
are not adjustable. This is why the round duct nozzle jet diffusers must be installed in accordance with the air flow direction
required so that the nozzles blow the supply air either horizontally to the left/right, or vertically into the room.
A hit-and-miss damper, which ensures that the supply air is discharged uniformly across the whole diffuser area, can be integrated into the diffuser. Because of the uniform admission, the
round duct nozzle jet diffuser type DSA-RR can be integrated at
any point along the duct system.
Accessories, such as dummy pipes, end covers and connecting
sleeves complete the range for this diffuser. (See documents:
Accessories for round duct systems).
Suspension
- prepared for suspended installation by using an M8
threaded rod to be provided by the customer.
Attention!
We would like to point out that for cleaning stainless steel models,
only suitable cleaning materials may be used!
In order to avoid corrosion-caused damage, we recommend
subjecting the components in the natural aluminium design onsite to an after-treatment by anodisation or painting.

Round Duct Nozzle Jet Diffuser Type DSA-RR
Division of length
1-part:
Length 500
Length 750
Models
Round duct diffusers with a
length of > 1000 mm are produced in two parts and joined
in-factory with a connecting
sleeve. Riveting nuts are not
required at this joint side.
The dimensions of the dummy pipe are the same as
those of the round duct grille
type DSA-RR.
A different division of length
is possible on special request. However, the maximum length for a middle or
end piece is 1000 mm.
DSA-RR-H
Both left- and right-hand air throws are possible. Therefore the
round duct must be installed in a turned manner.
