ROUND ALUMINIUM AIR DIFFUSERS FOR INSTALLATION IN FLOORS

The different attachments allow a wide range of applications with different air flows, installation conditions and several options for volume flow balancing.

Nominal sizes: 150, 200 mm
Volume flow range 1 – 59 l/s or 4 – 213 m³/h
Annular diffuser contour with different surface structures For constant and variable volume flows
For all types of raised floors Horizontal or vertical air flow
Reduction element adjustable on the front or rear side Can be installed with and without trim ring
The trim ring allows quick and easy installation and removal of the grille inserts for cleaning purposes
High mechanical strength/breaking resistance > 17 kN Ideal for comfort zones
Optional equipment and accessories
Swirl unit adjustable at the back for manual adjustment between vertical and horizontal air routing
Trim ring with spring clip fixing to cover the installation opening Dirt trap can also be used as a reduction element
Plenum box

General Information

Application Floor diffusers as supply air diffusers for comfort areas
Installation in raised floors without plenum box if it is constructed as a pressurised floor Installation in raised floors with plenum box to allow individual ventilation in rooms or zones Vertical supply air flow, with adjustable swirl unit also horizontal air flow
Variants with adjustable swirl units can be manually set to vertical or horizontal air routing
Attractive design element with various types of surfaces, for building owners and architects with demanding aesthetic requirements Comfortable and energy- efficient airflow through supporting convection currents in the occupied zone
Thermal loads are effectively dissipated For constant and variable volume flows
For supply air temperature differences of –12 – +20 K

Special features

Simple and quick assembly and covering of the installation opening when used with trim ring and spring clip fixing
Installation in hard flooring requires a spacing ring The spacing ring is included in the delivery if no trim ring has been selected High crush resistance > 17 kN
The grille insert is torsion-proof and centred in combination with trim ring With or without swirl unit to allow for various air patterns
A dirt trap reduces contamination of the floor and facilitates volume flow rate balancing. It can be adjusted from the diffuser front and back surfaceNominal sizes

Construction

Surface floor diffuser (floor grille and trim ring)
-1: Deburred diffuser core
-3: Deburred diffuser core, painted black, exposed surface overtightened
-4: Deburred diffuser core, exposed surface overtigthened
Parts and characteristics Grille insert Floor diffuser
Ring spacing: 6 mm
Height-adjustable dirt trap which serves as a reduction element for volume flow rate balancing Adjustable swirl unit for vertical or horizontal swirling air flow or air routing
Trim ring with spring clip fixing
Rotation lock and centring grille insert Covers the installation opening
Spring clip fixing enables different magnitude of the raised floor and the compensation of large cut-out tolerances when creating the installation openings. For the tightest possible fit of the trim ring, we recommend the minimum installation dimension
Balancing with soft flooring, e.g. carpetWorks well with soft flooring, e.g. carpet

Attachments

Spacing ring to hold the grille insert for variants without trim ring
Trim ring with spring clip fixing to accommodate the grille insert and to attach the installation opening Adjustable swirl unit for vertical or horizontal swirling air flow
Fixed swirl unit for vertical air flow (only for nominal size 200)
Height-adjustable dirt trap which also serves as a reduction element for volume flow rate balancing
