About Air Decor
Air Decor, based in Oldenburg, develops, produces and installs custom inflatables: inflatable stage sets, product replicas, archways, advertising columns, stand balloons, crowd balls, helium balloons, sky dancers, entrance tunnels, promotional tents, figures and bouncy castles. Manufacturing includes large-format printing on polyester (around 3,500 m² for the 6PM Festival project), sewing of the objects, fitting with continuous blowers and interior LED lighting; airtight models are made from TPU, standard models from polyester and PVC. For large outdoor objects, structural engineers perform static calculations and stability verifications including wind loads and load transfer, for example for the Wacken Open Air main entrances mounted on 40-ft containers. The service spectrum ranges from structural design and design drafts through production and quality assurance to shipping, on-site setup and rental (Chrome Spheres, Air Decor Tower). Customers come from festivals and events, sports, trade fairs, brand advertising, theatre, film and artist branding, including Wacken Open Air, Keinemusik, Telekom, Apache 207 and HUGEL (Coachella).
