Halton HEPA diffuser can be used both to supply and exhaust air.
The diffuser supplies the filtered air into the space. Adjustable nozzles allow creating the desired airflow pattern. Nozzles can be adjusted in 15 degrees intervals.
In case of exhaust application, the air is exhausted through the diffusers perforated front panel.
The installation of Halton Vita HEPA diffuser is performed by the ventilation contractor.
The diffuser is connected to the duct by screwing or by riveting. The duct connection spigot is equipped with a seal gasket. The diffuser can be installed:
CAUTION!
Do not drill any holes into the casing. If the casing has been damaged, unfiltered air may leak.
