The classification filters for vacuum cleaner and powders emissions into the environment, is assigned by the type of powders and the degree of danger to health. For its suction devices such classification is regulated by IEC 60335-2-69 worldwide. This classification provides several categories of powders, such as:
• Category of powders L (low/moderate): fall into that category powders with MPC values (maximum permitted concentration in the work place) > 1 mg / m³Are retained at least 99% of particles aspirated.The disposal of the collected material must be made trying to raise a few powders. • Category of powders M (medium): fall into that category powders with MPC values (maximum permitted concentration in the work place) > 0.1 mg / m³ and wood powdersAre retained at least 99.9% of particles aspirated.The disposal of the collected material must be made trying to raise a few powders. • Category of powders H (high): fall into that category powders with MPC values (maximum permitted concentration in the work place) < 0.1 mg / m³, with carcinogenic and pathogenic powdersAre held at least 99.995% of particles aspirated.The disposal of the collected material must be done without raising powders.On each iVision vacuum cleaner is applied a label indicating the hazard class of the dust in the environment allowed.
The gate valves that enable the closure of multiple vents allow the operator to choose to work with one, two or more hoses simultaneously. These gates can be operated manually by operators, handled automatically by machines, or remotely via foot pedal.
The cleaning kit is usable on all of the series and consists of a robust, anti-abrasion tube that ends at the extremities with special zinc-plated steel accessories capable of transporting, without any obstacle, chippings and oil from the machine tool to the vacuum collection tank. The suction tube comes housed inside a support in order to facilitate the movement of the vacuum in the workshop without being an obstable for the operator, it allows the avoidance of leakage of oil during the maneuvers of the vacuum.
HEPA is the acronym used for the definition “High Efficiency Particulate Air”.
It ‘a kind of filter for vacuum cleaner with a particular system of filtering with high efficiency for fluid, liquid or gas. It has the ability to trap a very high amount of particles of very small size, ability that other filters for vacuum cleaners do not have. Indeed, there are different categories of filters (L / M / H), and different categories of HEPA filters, that has made according to the material more efficient to inhale.
The HEPA filter is composed from microfiber filter sheets (generally borosilicate) assembled in multiple layers, and separated by aluminum septa. The microfiber filter sheets have the task to block the polluting solid particles (or particulate). The solid particles are very small and can be harmful to health or may affect the quality of the final product to be obtained.
HEPA filters are part of the category of the “absolute filters”, justified by the fact that these filters have a high efficiency of filterign. In particular, HEPA filters introduce an efficiency of filtering between 85% (H10) and 99.995% (H14). The filtration efficiency of particles of 0.3 µm, is regulated by the UNI EN 1822.
