Construction products detail

Supply and exhaust ventilation units

Supply ventilation units serve to supply indoor spaces with filtered and possibly preheated outside air.

Exhaust ventilation units serve to remove exhaust air from indoor spaces.

Regulatory framework

Mass-produced, ready-to-connect ventilation units with a volumetric flow rate of ≤ 1,000 m3/h that are permanently installed and operated in buildings are relevant from a regulatory point of view.

Further measures such as, e.g., wall vents, may be required to ensure adequate air exchange.

In this work area, DIBt grants national technical approvals (abZ) and/or general construction technique permits (aBG). European Technical Assessments (ETAs) can also be issued for corresponding products.

Please also note the applicable design and execution rules for ventilation technology, cf. in particular MVV TB, Parts A and B and the following information and technical rules.

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

Please feel free to use the template below.

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
