TELLUS-PBM-LØV  

CIRCULAR SUPPLY DIFFUSER FOR EXPOSED INSTALLATION

Tellus-PBM-LØV is a circular supply air diffuser for exposed installation, combining the well-known Tellus-LØV diffuser with a new patented modular plenum solution. The new plenum solution provide increased flexibility, extended product lifetime and reduced environmental impact in buildings with changing requirements.

Marketing highlights:

  • Patented modular plenum (PBM) enabling conversion between installation types
  • Possibility to rebuild without replacing the diffuser
  • Extended actual product lifetime in buildings with frequent changes
  • Design-protected LØV perforation
  • Prepared for X-SENS-TPDM sensor (Temperature, PIR, Diffuser Mounted)

General information

Application
Tellus-PBM-LØV is a circular supply air diffuser designed for exposed installation.
The diffuser provides excellent induction and is suitable for both constant and variable air volume systems. It is particularly well suited for installations where visible ventilation components are desired or required. The integrated PBM plenum enables the product to function as both an air distribution device and a measurement and regulation unit.
The modular PBM design allows the product to be adapted if installation requirements change, for example when converting from exposed installation to ceiling installation. This makes the product especially suitable for buildings with frequent refurbishment or changing tenant requirements.


Functional description
Tellus-PBM-LØV distributes supply air through a front panel with design-protected LØV perforation. The airflow pattern is rotational as standard, ensuring high induction and efficient mixing of supply air with room air. The diffuser features a fixed slot height, allowing easier commissioning.
The PBM plenum:
  • ensures even airflow distribution
  • incorporates an airflow adjustment damper
  • includes measurement outlets for commissioning
  • contributes to sound attenuation
  • The integrated damper can be locked in any position for precise airflow regulation.
The product can be equipped with the X-SENS-TPDM sensor, integrating temperature measurement and presence detection (PIR), enabling demand-controlled ventilation.
Design
Tellus-PBM-LØV features:
  • circular design for exposed installation
  • removable front panel with LØV perforation
  • fixed slot height
  • rotational airflow pattern as standard
The PBM plenum introduces a cylindrical, modular design replacing traditional fixed plenum solutions.
PBM – Plenum Box Modular:
  • cylindrical plenum design
  • patented solution enabling conversion between installation types
  • adaptable between exposed installation and ceiling installation
  • modular construction allowing reconfiguration without replacing the diffuser


The modular design enables reuse of the product in new configurations, reducing the need for replacement.


Material and surfaces
The diffuser is manufactured in steel.
Standard finish:
Diffuser front powder coated in RAL 9006 gloss 30, for an unpainted steel design.
Optional finishes:
Special RAL or NCS colours on request. The diffuser front and plenum box will then be painted in same color.
The PBM plenum:
  • manufactured in galvanised steel
  • internally lined with sound absorbing polyester material
  • equipped with EPDM rubber gasket on connection spigot
The LØV front panel ensures robust construction and consistent airflow performance.


Commissioning
The PBM plenum includes:
  • integrated airflow adjustment damper
  • measurement outlets for airflow verification
The damper is accessible via the removable front panel. This enables simple commissioning, accurate airflow adjustment and easy re-balancing if system requirements change.


Maintenance
The removable front panel provides easy access to:
  • damper
  • measurement points
  • internal components
Maintenance is minimal and typically limited to inspection and cleaning.
The product is designed for long service life and stable performance.


Environment
Tellus-PBM-LØV is designed to support sustainable building solutions by extending the actual service life of ventilation products.
In modern buildings, ventilation products are often replaced due to layout changes rather than technical limitations. The patented PBM concept enables reuse by allowing the product to be rebuilt and adapted between different installation types.
This reduces the need for replacement and contributes to:
  • reduced material consumption
  • lower waste generation
  • decreased environmental impact from production and
transport The product is designed for durability, easy maintenance and long-term performance.
