Velco supply air valves are an excellent choice for a wide range of applications. In addition to ready-made valve assemblies, we offer fully site-specific, customized solutions that are individually assembled according to the requirements of the installation site. This allows consideration of, for example:

• sufficient sound attenuation
• required air flow rates
• the number of wall duct sections according to wall thickness
• exterior grilles compatible with the façade
• installation method and structural special features

With a wide selection of components, valve assemblies can be configured to precisely meet the technical requirements of each project. Velco supply air valves are available in four sizes: ø80 mm, ø100 mm, ø125 mm, and ø160 mm. The product range also includes supply air valves, exterior grilles, installation ducts, and mounting plates in several different models – all designed as fully compatible systems.



Velco supply air valves are suitable for all buildings with natural (gravity-based) or mechanical exhaust ventilation. Depending on the model, the valves can be installed:

• through a new wall penetration
• in a wooden ventilation hatch
• as a replacement for an existing valve
• or inside a metal hatch
