Industrial fans are the heart of aspiration systems. Actually, they are the main components generating and handling airflow and its necessary aspiration in all filtration and purification systems for air polluted by contaminants generated in several industrial applications.
Chemical and Pharmaceutical Industry
Suction arms are the ideal solution for the elimination of various contaminants released by industrial processing processes. Aspiration takes place directly in the point where the harmful substances are emitted, avoiding damages to workers’ health.
The easy carrying of wheeled and fixed filter units makes them suitable for several workplaces, even the smallest ones. The easy positioning of these wheeled units, with the possibility of installing also a suction arm, allows to get as close as possible to the emission zone of the pollutant.
Compact cartridge filters are mainly used in indoor and small spaces. The compact and sturdy design integrates all the necessary elements for an efficient aspiration and filtration process of dry fumes and dust.
Horizontal cartridge filters for fumes and dust filtration, including plasma cutting fumes, ensure easier and faster filters replacement and maintenance operations, thanks to their different set up.
Industrial processing generating limited concentrations of fumes and dust can use mechanical dry filtration of cartridge filters, equipped with a wide filter surface which is able to clean inlet air, retaining and separating solid particles.
Bag filters are used in several industrial processes of dry processing of materials. They’re equipped with bags in different materials depending on the pollutant to retain and their wide filtering surface can extract and filter high concentrations of dry fumes, very fine dust and metal particles. They’re available both in standard and ATEX version.
The vertical or horizontal configurations of washing towers share the same working principle: the elimination of contaminants is performed through the contact between the polluted airflow and the washing liquid.
The Regenerative Thermal Oxidizers or Combustors are aspiration and filtration systems which eliminate organic substances present in the airflow through combustion or thermal oxidation. Their main distinguishing advantage is the heat and energy recovery system.
Carbon filter filtration is an air purification technology which uses the excellent absorbent property of this material to filter and eliminate the odorous factor of the air polluted by volatile organic substances.
The natural, ecological and economical bio-filtration biological process is easily and efficiently applied in all industrial sectors which release harmful and odorous organic substances in the air and, therefore, require its abatement.
In compliance with the European directive in force, ATEX filters are specifically designed to be used in potentially explosive workplaces which are exposed to the emission of dust or flammable materials which may be a dangerous source of ignition.
Several applications take advantage of the efficient mixture of air and water typical of hydrodynamic functioning of wet filters, compared to common dry filters.
The particular design of suction benches, studied to avoid that the pollutant reaches the worker during processing on the countertop, allows dry fumes and dust aspiration at the source of production directly. Aspiration is performed within the work surface and air is filtered through filtering cartridges inside of the suction bench. Aspiration ends with the backwash compressed air cleaning of cartridges.
Suction walls are designed for big quantities of fumes and dust and perform a frontal extraction of fumes and dust deriving from processing which are carried to internal filtering sections of the wall or to an existing aspiration and filtration system.
Cyclone separators are designed for the elimination of coarse dust, shavings, sawdust, metal dust, thanks to the efficient principle of centrifugal force. Their positioning allows the abatement of dust before the filtration in a more complex system. Cyclones dimensions are calculated according to the airflow rates of the system and the quantity of pollutant to be eliminated.
Maintenance and cleaning of the workplace from waste and scraps are usually performed by industrial vacuum cleaners which are suitable for the aspiration of more or less polluting dust, solids or liquids, depending on their features.
