Use
The “CLEAN and “CARBO” modular filtering units are used to clean and deodorize air polluted by welding smoke, gas and vapour, fumes, etc…
Operating principle
Before being allowed back to the environment, the polluted air leading from the suction points is ducted to the “CLEAN” filtering unit which mainly comprises: 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 fibre. 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) . 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 is contained in cylinders made of microperforated metallic net which allow easy change of the carbon.
Functionality
Thanks to its modular construction, the high efficiency of the filters and the remarkable withholding capabilities of the active carbon, it is possible to optimise 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 best performance the “CLEAN” “CARBO” should be used in vacuum.
Energy saving
The filtered air may be re-introduced into the working environment to obtain considerable energy saving for special applications where permitted by local laws.
Accessories
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.
