Air conditioners are equipped with compressors or ventilators generating low-frequency vibrations, and are often installed in buildings (on roofs) where we will find acoustic and vibratory nuisances which can weaken the structures.
The air conditioners can be also be fixed inside vehicles (trains, trucks, bus) and must be protected from shocks & vibrations (for the passengers comfort).
Paulstra proposes a wide range of suspensions to answer to these requirements.
