3 Product information
3.1 Functional description
The product is a compact filter system which extracts and filters air
containing pollutants, the properties of which are listed in the chapter
"Intended Use".
The captured pollutants are also transported to the product in the air
stream via a ducting system. The polluted air flows past the baffle plates
installed in the product. These protect the filter cartridges against coarser
particles. The polluted air then passes through the filter medium.
The deposited particles collect on the surface of the filter cartridges and
result in a slow increase in the pressure difference at the filter cartridges.
This is assessed by the intelligent control system that initiates a cleaning
process as required. A blast of compressed air is precisely distributed across
the total filter surface of each filter cartridge via a rotation nozzle. The
deposited particles are dislodged and fall into the dust collection container
in the lower section of the product. The filter cartridges are cleaned during
operation. Work does not need to be interrupted. So-called ‘post-cleaning’
is performed once the product has been switched off. This cleaning
method is the more effective of the two.
The cleaned air flows up through the inside of the filter cartridges into the
clean air area of the product from where it is either returned directly to the
working space or routed outdoors via an exhaust pipe.
