6 POSITIONING AND ANCHORING THE FILTER BENCH

WARNING!

Given the crucial importance of the absolute filters, you must be careful that they have
been placed in special packaging and have not been subject to any type of impact or
damage.

WARNING!
Before installing the filters in the final position, start the primary air handling unit and the
recirculation modules in order to remove any dust and material residue from the aeraulic
ducts, deriving from the positioning and installation operations.

6.1 LAYING THE FILTERS OF THE FILTER CEILING

The filtering system of the filter ceiling has been designed to differentiate the speed of the air leaving the filter bench. For
this purpose, the filter bench has been split into two crowns - internal and external; the external crown consists of low speed filters
whereas, the internal crown consists of high speed filters.
Therefore, it is very important to pay attention to the type of filter to be installed while installing filters.
