ROS-A FA4100

The ROS‑A FA4100 Large Duct‑mounted Plasma Fresh Air Unit adopts the ROS‑X™ TD‑L large tubular plasma generator (350*4) with a set of four large plasma tubes. It satisfies deodorization and disinfection demands for moderate‑to‑severe air pollution in large‑volume spaces.
The ROS‑A FA4100 Large Duct‑mounted Plasma Fresh Air Unit generates substantial ROS multi‑ion groups composed of reactive oxygen species and free radicals. It actively removes various odorous molecules in the air for fast odour elimination, while inhibiting bacteria, viruses and mould.
