We already saw in a previous note what are the wet and dry vacuum cleaners —And we also saw a special note about ash vacuum cleaners-. We then have to develop the idea of ​​how to choose a vacuum cleaner of these characteristics that helps us in our work, according to the nature of it.

Not all machine tools they produce the same type of waste; sometimes it is shavings, other times sawdust, dust, liquids or even ashes. It is important to have a guide to choose one vaccum cleaner capable of handling that waste; Here’s how to do it.

How to choose a vacuum cleaner according to the tool and type of work

As we have already seen in previous notes, many machine tools have a port that allows you to connect the tube of a vaccum cleaner to avoid the emission of particles into the atmosphere: from drills to gutters, the tendency is to prevent the projection of these residues at the root.

Some tools provide a bag, similar to those used in vacuum cleaners household, to collect dust, sawdust or shavings, but it happens that on many occasions that bag is not enough, whether the work is intensive or extensive. In these cases is when to choose a vaccum cleaner it becomes fundamental. But which one to choose?

We can divide the choice into two large groups according to the type of waste generated: dry waste and wet waste. The distinction is important since the type of filter to be used depends on it.

Jobs that generate dry waste

In this group we can find tools such as sanders, drills, grooves, grinders and others. They all generate dust, shavings or sawdust, but these particles always share the characteristic that they are dry.

In addition to being able to supplement all these tools, the dry vacuums They allow to clean by themselves the residues left after the operations.

Among the most common trades that would benefit from choosing a vaccum cleaner of this type we can count the brickwork (removal of fine debris and brick dust, paint, etc.), the carpentry (collection of sawdust, which can then be stored in bags for sale or reuse), the metallurgical (aspiration of chips and filings) and spare parts, painting, wallpaper, etc.

Jobs that generate wet waste

There are not many tools that in themselves generate this type of waste, except perhaps those that are used to process organic materials.

The vacuum cleaners for wet waste They are extremely useful, on the other hand, for cleaning sumps and gutters, emptying coolant tanks (soluble oil, many times it acquires unpleasant odors when it decomposes as a result of the appearance of bacteria) and cleaning the residue resulting from the wall cleaning process with pressure washers .

So the most common uses for wet vacuums is the cleaning and suction of all types of wet or liquid residue, and complement rather than supplement the action of other tools.

Trades that frequently use this configuration are industrial oven and grill cleaners, factory maintenance personnel – who remove old coolant from machines – plumbers (cleaning sinks, patio sinks, pipes and others) and workers in the industries pharmaceutical companies (although they also use dry waste filters).

The best choice in these cases is that of a wet vacuum autonomous —with its own engine— whose tank is metallic, since with it we can also suck up ashes (dry residue) just by changing the filter for a HEPA one.

Is it possible to choose a model and just change the filter?
