Description

Negative detail diffuser for unobstructive integration in interior designs. With minimal to no draft and no Coanda effect to keep ceilings clean, the vent meets highest expectations. The vent can also be used for extraction.

Highlights

• Negative detail – only 18mm wide
• For supply and extract air
• Airflow up to 112m³/h per meter
• Standard 125mm spigot
• Compatible with BlauFast RPZ125 valve connector
• Insulated (double wall)
• Optional Butterfly Damper, adjustable from room
• Dummy profile available for continuous slot design

Installation
The Kiefer INDUL vent can be installed hanging on installation rods (not included in delivery). The 125mm spigot is compatible with the Blauberg BlauFast system:
Connect 2x 90mm BlauFast ducts (RK90) with valve adaptor RPZ125/90×2 to spigot of 1m Kiefer INDUL diffuser. Respective only one duct is needed for 0.5m INDUL diffuser.

About INDUL Linear Diffuser
Slimline linear diffuser for maximum thermal comfort and unobtrusive installation in all types of ceilings, even where space is at a premium. The reliable free jet characteristics prevent dirt deposits along the air diffuser, keeping ceilings clean for longer.

Energy
The extremely high induction rate of INDUL linear diffusers enables draught-free operation even at very low supply air temperatures. This creates significant potential for saving energy through the use of free cooling.

Design
The slender diffuser profiles blend perfectly into any ceiling architecture and keep ceilings dust-free for longer. Whether unobtrusive or deliberately accentuated, they will meet all architectural requirements.

Technology
INDUL free jet characteristics are unique in enabling a continuously diffuse ambient air flow and allow temperature differentials of down to -14 K, without the slightest compromise on thermal comfort.

Function
The supply air is divided into fine alternating free jets, which intensifies the induction of ambient air. This high level of induction permits a substantial temperature differential between the ambient air and supply air, and in particular the use of free cooling. The required cooling capacity is reduced to a minimum. Effective insulation of the plenum box largely prevents energy losses despite the low temperatures. And thanks to the use of recycled aluminum, the INDUL air diffuser scores highly on lifecycle costs, as evaluated by current certification systems.

The classical ambient air flow
The specially developed discharge geometry produces fine individual air jets. Ambient air can be effectively induced at the edges of the individual jets. Through the induction (admixture) of ambient air, the temperature differential between the supply air and ambient air is balanced out over a short distance. The discharge velocity of the supply air is also reduced by the time it reaches the occupied zone, with the result that no draughts are perceived.

About Kiefer Klimatechnik Germany
Since 1877, the way Kiefer thinks and acts has revolved around optimum solutions and products. The aim has always been to create ventilation and air-conditioning technology that is fit for people, does not harm the environment and saves energy – and today more than ever. Customers’ satisfaction is very important to Kiefer. This means that Kiefer are on hand during every phase of the project: from the initial sketch through the finished project all the way to installation and maintenance services.
