An air diffuser ensures draught-free air distribution in all situations across a wide variety of rooms, acting as the terminal point of the air duct in air-handling units (AHUs). Together with connection boxes and ventilation valves, air diffusers form the interface between the ductwork system and the occupied space, making a crucial contribution to a comfortable indoor climate and energy-efficient air distribution.

Wildeboer offers a comprehensive range of ceiling air outlets to meet a wide variety of requirements in office buildings, schools, hotels, retail spaces, meeting venues, and industrial and administrative buildings. Depending on the application, solutions for supply and extract air are available, as well as options for different air flow rates, installation scenarios and architectural requirements.

Air outlets for various applications

The requirements for air distribution vary depending on a building’s use. In addition to a high level of thermal comfort, air quality, acoustics, energy efficiency and harmonious integration into the architecture play an important role.

The product range comprises various air outlets designed for different flow patterns and applications. These include, amongst others:

  • swirl diffusers for maximum induction and very rapid equalisation of temperature differences
  • linear diffusers for high air flow rates at low sound power levels
  • slotted diffusers with adjustable air deflectors for single-sided, double-sided, alternating and vertical airflow
  • ventilation valves for supply and extract air applications
  • other air diffusers for different room and usage concepts

Wildeboer air outlets: their benefits

  • Suitable for supply and extract air applications
  • Different flow patterns for various room layouts
  • Supports energy-efficient air distribution

Plenum boxes as a component of an efficient air distribution system

Plenum boxes for air diffusers ensure a uniform airflow to the diffuser and promote optimum air distribution. At the same time, they simplify the installation of the air outlets and – depending on the design – allow for precise adjustment of the air flow rate.

Depending on the requirements, connection boxes are available in various designs – particularly for confined spaces – and with different features. This allows air diffusers to be optimally adapted to the respective ventilation system.

Wildeboer plenum boxes: the benefits

  • Suitable for installation in closed ceiling systems, grid ceilings and free-hanging ceilings
  • Uniform airflow from the ceiling air diffuser
  • Optional damper and special air deflectors available for optimal air distribution with minimal airflow noise

Air valves for supply and extract air

Air valves are suitable for use in supply and extract air systems and are fitted in residential, commercial and public buildings alike. They enable controlled air flow and support the hygienic operation of modern ventilation systems.

Thanks to various sizes and adjustment options, the valves can be adapted to different air volumes and installation situations.

Wildeboer air valves: their benefits

  • For supply or extract air applications
  • Installation in ceilings, walls and as a free-hanging unit
  • Stepless airflow adjustment via a rotatable valve disc

Configure products with ease

For quick and application-oriented product selection, Wildeboer air inlets and ventilation valves can be configured using the Wildeboer Configurator in Wildeboer Connect. Based on project-specific requirements, suitable product variants can be selected and technical specifications customised.

Once configuration is complete, relevant technical information, tender documents and other planning documents are available, depending on the product in question.

Frequently Asked Questions about air outlets, plenum boxes and air valves

An air outlet is the visible terminal element of a ventilation system, through which air is supplied to or extracted from a room. It influences air distribution, airflow within the room and comfort levels in the occupied area. Depending on the application and installation situation, there are various designs available, for example for ceiling, wall or floor installation.

Depending on the room layout and air flow pattern, air outlets can be positioned in ceilings, walls, floors or parapet areas. Key factors influencing the selection include the desired air distribution, the air flow rate, the room geometry and the need to avoid draughts in the occupied area. Their positioning should therefore be tailored to the intended use, comfort requirements and installation conditions as early as the planning stage.

For several Wildeboer products, the airflow can be adjusted using suitable components. Plenumboxes can be optionally fitted with damper flaps, allowing the airflow to be adjusted without dismantling the air diffuser. For VSA and VSZ ventilation valves, the airflow can be continuously adjusted via the rotatable valve disc.

Wildeboer plenum boxes for ceiling air diffusers are suitable for closed ceiling systems, grid ceilings and free-hanging installations. A range of installation heights and connection options allow for flexible adaptation to the specific design and construction of the ventilation system.

Different plenum boxes are available depending on the ceiling air diffuser. For many swirl diffusers and air diffusers, square connection boxes with a side connection spigot, two side connection spigots or a top connection spigot are available. For certain diffusers, round connection boxes with a side or top connection spigot are also available. The K4 plenum box is designed for the DF swirl diffuser.
