The dust-vapor mixture is fed to the box filter named Full Filtering, patented by OCM Clima.
It is made of painted sheet RAL 9002 and installed upstream of the electric fan. The fan processes the mixture before it is emitted into the atmosphere.
The functionality of the filter is based on the principle of the droplet separator, which fosters the phenomenon of coalescence and is self-cleaning, thanks to a compressed air system managed by a control unit connected to the software Aspharia.
The filter is provided with a big storage capacity and it requires an occasional, fast and particularly simple maintenance.
