EMT-R-U Cylindrical Extract Diffuser (No Damper)

APPLICATION AREAS
This is a single-row curved-blade grille without a damper. It is used as a return air grille. To allow installation on cylindrical air ducts, it is manufactured according to the required duct diameter. The center blades are designed to be adjustable for air direction control.

FEATURES
The grilles are manufactured using specially rolled aluminum profiles. After applying special filler to the joints between the grille and the outer frame and sanding the surface, they are chemically cleaned and coated with electrostatic powder paint. Standard dimensions are provided in the tables. Custom production in any size is available upon request.

IMPORTANT NOTE
For this type of grille, the duct diameter to which the grille will be mounted must be specified at the time of order. Depending on the installation method, the specified dimensions are given as (L × H), where L = width and H = height. As standard, the grille is manufactured 10 mm smaller for duct mounting. If specified, production can be made according to net dimensions.

INSTALLATION MATERIALS, PACKAGING & TRANSPORTATION
Mounting screws are supplied with the grilles. Packaging is carried out using polyethylene film. Since the grilles are fragile and may deform, transportation must be handled with care. Standard dimensions are provided in the tables; custom production in any size is available upon request.

SAMPLE ORDER FORMAT
For this type of grille (wall-mounted), the first dimension written, 400 mm, refers to the horizontal size (blade length), and the second dimension, 200 mm, refers to the vertical size.
