Pocket filters have a wide filter surface which is able to capture and collect large quantities of polluting particles of dry fumes and dust, while maintaining low rates of pressure loss.
Modular and compact filter unit, easy to be inserted and replaced as a whole in the aspiration system.
Maximum efficiency and long operating durability: the wide filter surface can retain high quantities of dust.
Flexibility of use in different applications.
Clean e Assoclean
Modular filter units made of an average efficiency pre-filter, respectively followed by a high efficiency pocket filter in glass micro-fiber and an absolute filter, which are suitable for the extraction and filtration of air polluted by welding fumes, gas and vapors.
Filtri a tasche
The “CLEAN – ASSOCLEAN” and “CARBO” modular filtering units are used to clean and deodorize air polluted by welding fumes, gas and vapors.
Before being allowed back to the environment, the polluted air leading from the suction points is ducted to the “CLEAN” filtering unit which mainly includes: a pleated average efficiency pre-filter (87,5% measured according to the ASHRAE 52-76 st.d class G3) made of an electrically-welded galvanized frame which encloses the filtering sector of synthetic resin primed, polyester fiber; a high efficiency filter with pockets made of microfibers connected to a galvanized sheet metal frame (95% efficiency measured according to the ASHRAE 52-76-st.d class F9). As a second high efficiency filtering stage, the ASSOCLEAN unit is available, equipped with absolute filter HEPA 13 with filtering efficiency 99,95% and medium efficiency prefilter classified G3 same as the CLEAN unit. If the deodorizing or the absorption of chemical substances or solvents in the air is required, for example, during painting operations or when plastics are processed, the filtered air is passed through the “CARBO” unit which is firmly bolted to the “CLEAN” module. The active carbon used in the “CARBO” unit has a specific area of 1250 sq. m/g, a volume mass of 500 Kg/m3 an iodine value of 1150 mg/g and it’s contained in cylinders made of microperforated metallic net which allow easy change of the carbon.
Thanks to its modular construction, the high efficiency of the filters and the remarkable retention capabilities of the active carbon, it’s possible to optimize the sizes of the unit according to the amount of air to be treated for capacities between 1500 cu. m/h and 27.000 cu. m/h with filtering areas between 3,3 sq. m. and 61 sq. m. For a best performance the “CLEAN” “CARBO” should be used in vacuum.
The filtered air may be re-introduced into the working environment to obtain considerable energy saving for special applications where it’s permitted by local laws.
Fans of the “PRM-PR-PRA” series can be used according to the different requirements. These fans operate either under pressure or vacuum. Stainless steel CLEAN/CARBO units are available upon request.
