VACUUMS & SWEEPERS
INDUSTRIAL VACUUMS: WHAT TO LOOK FOR
In an industrial setting, it is vital that you have the right cleaning products to cope with the more
heavy-duty requirements of the job. With that in mind, The Preparation Group talk us through what to look for when selecting your industrial vacuum.
For collecting dust, debris, contaminants, liquids and spillages, quickly and efficiently there is a solution for every industrial cleaning application. However, the correct vacuum selection is paramount.
The chosen dust extraction unit must match the operation in terms of the size of motor, level of suction power, filtration capabilities and the dust ‘bin’ capacity, otherwise the process will be ineffective and there will be dust contamination. Not all vacuums are the same. For maximum efficiency and durability, look for robust models with easy cleaning and changing of filters and energy saving models that can multi-task.
Questions you need to ask are; what is the available power; what is the material composition; the type, volume and density of the dust or debris, and is there a specified filter grade.
For light applications, a single motor vacuum with a small bin capacity may be suitable for the task.
For mid to large operations, there are models with two or three motors that are individually powered, allowing the operator to select the level required for the specific task. Statistics show that for most daily operations, 80% of the time only 50% of the available power is needed without impeding on suction capacity and performance. Industrial vacuums such as the 202DS and M450 models have this energy saving feature.
The next consideration must be the size of the ‘bin’ or bag attachment in which the dust is contained prior to disposal. The capacity must be suitable to deal with the quantity of dust and large enough to contain the debris for the duration of the operation. It is not practical to have to continually empty the ‘bin’ or to seal bags.

When there is a need to vacuum both wet and dry materials, there are dual purpose dry/wet industrial models on the market that effectively remove both, without the need to change the filter system.
For situations where dust is critical or where toxic and hazardous substances are present, there are vacuums that feature a Longopac® Safe Bagging System such as the 202DSLP or M450LP. Here, instead of a bin, dust and solid material is collected into a continuous anti- static feeding bag which is twisted and sealed by the operator into bags for disposal. This gives the operator confidence that airborne particles are safely contained.
With any operation, it is essential that the correct filter is fitted. In many projects clarifying the filter grade capacity and the level of filtration in comparison with the intended operation and the level or type of dust produced is essential. There are three main types of filters; L, M and H (low, medium and high). A vacuum must be fitted with an L or M type filter in order to correctly function, but can also be fitted with an additional H grade filter for collecting very fine particle dust and dust containing asbestos. A vacuum fitted with an H filter is by definition an H-type Vacuum. L grade filters are only suitable for containment of sand shed particles and the simplest applications.
Vacuums fitted with an H grade filter should have an ‘H’ sticker on them. To double check that one is fitted, take the head off the vacuum to confirm that there are two filters inside (one will be an H filter).
