A new chinese restaurant opened in the Atrium City Center in Linz/Austria. The requirements about the airtightness of the exhaust air were particularly strict. Instead of the very clean execution of the installation, the responsible technician asked for an additional sealing of the exhaust air ductwork. As a consequence, the already installed ductwork was sealed from the inside out using the Aeroseal technology.
Building: Chinese Restaurant "Xu Atrium"
Date: March 2016
AEROSEAL Partner: Aeroseal Austria GmbH
Executing company: LSA Luft-Systeme Althuber GmbH
Target: Prevention of odour nuisances and additional airtightness of the kitchen exhaust air
Preseal leakage: 1,7 l/s @ 200 Pa (15,2 m²)
Postseal leakage: 0,5 l/s @ 200 Pa
Reduction of leakage: 70%
After the application of the Aeroseal technology, the exhaust air ductwork corresponds to an airtightness class D. The initial leakage was a class B.
