When you buy a vacuum cleaner, you generally pay attention to its technical characteristics, such as the engine power, the types of materials sucked in, the capacity of the container, the air flow and the head. In rare cases, we focus on the filtration system present in the machinery.
Still, the filter is one of the most important parts of the industrial vacuum cleaner. This is because the quality of the air that is reintroduced into the workplace and, therefore, the safety and health of the operators depend on it. Furthermore, another essential function of the filter is to protect the suction head (whether this consists of a fan or a side channel blower), the beating heart of the suction unit, to prevent it from being damaged by the sucked material.
Depending on the type of dust and its level of danger, the filters are divided into different categories according to the IEC 60335-2-69 regulation:
- Class L: moderate risk. The filter is capable of retaining 99% of dust smaller than 2 microns. This classification includes dusts with MAC values (Maximum Allowable Concentration in the workplace) bigger than 1 mg/m3.
- Class M: medium risk. The filter is capable of retaining 9% of dust smaller than 2 microns. This classification includes dust with MAC values bigger than 0.1 mg/m3 and dust derived from wood.
- Class H: high risk. The filter is capable of retaining 995% of dust smaller than 1 micron. This classification includes dusts with MAC values lower than 0.1 mg/m3, carcinogenic dusts and those contaminated with pathogens.
The filtering system of your industrial vacuum cleaner is therefore not a trivial matter. For this, at iVision Vacuum we use very high quality filters, capable of capturing any impurity or particle. To prevent these from being reintroduced into the work environment and therefore putting workers’ health at risk, it is necessary that the filter is cleaned often, making sure that it works properly.

FILTRO HEPA
AccessoriosACCESORIOS ASPIRADORES INDUSTRIALES IVISION
HEPA es el acrónimo utilizado para la definición "High Efficiency Particulate Air". Es un tipo de filtro para aspiradora con un sistema particular de filtrado de alta eficiencia para fluidos, líquidos o gases. Tiene la capacidad de atrapar una cantidad muy alta de partículas de tamaño muy pequeño, capacidad que otros filtros para aspiradoras no tienen. De hecho, hay diferentes categorías de filtros (L / M / H), y diferentes categorías de filtros HEPA, que ha hecho de acuerdo con el material más eficiente para inhalar. El filtro HEPA se compone de hojas de filtro de microfibra (generalmente borosilicato) ensambladas en múltiples capas, y separadas por septos de aluminio. Las hojas del filtro de microfibra tienen la tarea de bloquear las partículas sólidas contaminantes (o partículas). Las partículas sólidas son muy pequeñas y pueden ser perjudiciales para la salud o afectar a la calidad del producto final que se desea obtener. Los filtros HEPA forman parte de la categoría de los "filtros absolutos", justificada por el hecho de que estos filtros tienen una alta eficacia de filtrado. En concreto, los filtros HEPA presentan una eficacia de filtrado comprendida entre el 85% (H10) y el 99,995% (H14). La eficacia de filtración de partículas de 0,3 µm, está regulada por la norma UNI EN 1822.
