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.

过滤 Hepa
AccessoriesIVISION 工业真空吸尘器配件
HEPA 是 "高效微粒空气 "定义的缩写。 它是一种用于吸尘器的过滤器，具有对流体、液体或气体进行高效过滤的特殊系统。它能够捕获大量极小尺寸的颗粒，这是其他吸尘器过滤器所不具备的。事实上，过滤器有不同的类别（L/M/H），HEPA 过滤器也有不同的类别，根据材料的不同，吸入效率也不同。 HEPA 过滤器由多层组装的超细纤维过滤片（一般为硼硅酸盐）组成，并由铝隔板隔开。微纤维过滤片的任务是阻挡污染性固体颗粒（或微粒）。这些固体颗粒非常小，可能对健康有害或影响最终产品的质量。 HEPA 过滤器属于 "绝对过滤器 "的范畴，因为这种过滤器的过滤效率很高。HEPA 过滤器的过滤效率在 85% (H10) 到 99.995% (H14) 之间。UNI EN 1822 标准规定了 0.3 µm 微粒的过滤效率。
