Air flow control adapted to needs | Sound absorber | optimum discharge setting
Thermal comfort
Excellent ambient air flow through inductive adjustable air diffuser profile.
Innovative mechanism
Air flow control and discharge setting adapted to needs for constant comfort.
Integrated sound absorber
No extra installation necessary. Compact ready-to-use solution.
INDULFLOOR. The flexible floor air diffuser.
Compact, quiet and variable.
INDULFLOOR is a compact floor air diffuser with an integrated sound absorber and innovative mechanics for demand-based air volume flow control and discharge setting. The settings can be adjusted either manually or electrically via actuator/controller. The walkable linear grille with support frame and the asymmetrically positioned air connection nozzle allow for flexible installation. Four height-adjustable feet compensate for construction tolerances, while the mounting console provides a simple interface to the raised floor, allowing the floor covering to be applied directly. The integrated pressure tap enables precise on-site air volume adjustment, optionally available as a pressure-independent air volume control with Modbus communication.

| Length | 1100 mm |
| Total height incl. adjustable feet | 193 - 243 mm |
| Recommended line pressure range* | between 30 and 60 Pa |
| Air flow rate range per outlet | 30 - 160m³/h |
| Sound power level | LwA 31 dB(A) at 130 m³/h and 26 Pa |
| Temperature differential ΔT | down to - 6 K |
| Air flow setting: | manual, electrical: 2-stage / continuous / variable control |

* Minimum pressure loss for the version with an electric air flow controller: 2 to 30 Pa, depending on the air volume flow.

| Installation | Low box height for problem-free installation in raised floors, without clearance to the façade. |
| Components | Compact, ready-to-use solution: air diffuser, air flow rate and discharge setting (optionally with actuator or air flow rate controller), sound absorbing. |
| Assembly/installation | Single-piece for ease and speed of installation. |
| Commissioning | No adjustment needed, factory preset. |
| Air flow rate control | No access hatch needed, as the air flow rate can be adjusted manually from the room or electrically. The pressure measurement nipple is used to measure the set air flow rate. |
| Ambient air flow + thermal comfort | Inductive air diffuser profile for optimal mixing/source flow, independent of the set air flow rate. Subsequent increase or decrease of the air flow rate is possible without impacting comfort. |
| Acoustics | Sound absorbing integrated into the air diffuser. |
| Cleaning | Floor trough of linear diffuser can be cleaned according to VDI 6022 by removing the floor grille and air diffuser profile. |
| Flexibility | Electric actuator or air flow rate controller can be retrofitted from the room side. |
| Energy | Energy-efficient ventilation with minimal pressure loss. Electric adjustment and variable air flow rate control enable energy and cost savings through demand-driven ventilation. |
INDULFLOOR is installed directly onto the unfinished floor. Installation tolerances are easy to compensate for with the height-adjustable feet so that the diffuser can easily be aligned then secured to the floor with the impact-noise decoupled fixing tabs. The INDULFLOOR has an access panel to which the floor covering can be applied directly. The floor panels of the raised floor can be recessed in the area around the INDULFLOOR, thereby reducing the overall installation height. The INDULFLOOR can be installed as a single diffuser or as a band arrangement.
An innovative mechanism ensures an almost constant flow pattern, regardless of the air volume flow. The air flow rate and discharge impulse can be easily adjusted using a slide damper with a scale, accessible from the room. Optionally, a demand-based electric air flow rate adjustment or control with an actuator and Modbus communication is available. A pressure measurement nipple on the room side allows for air flow rate determination.
