Air flow filtration consists of the elimination, or reduction to acceptable thresholds, of all contaminating substances suspended within it: these can range from dust and fumes – substances characterized by relatively coarse and dry particulates – to oil mists or odor molecules, which are conversely moist and of much smaller dimensions.

Such a difference in possible suspended particulates obviously requires filters of a completely different type, with different technologies and efficiencies, for air dust and odor removal.

In industrial settings, filtration takes place between the air intake and emission phases. The reasons why industrial air flow filtration is necessary are fundamentally threefold:

First, there are safety and health reasons for workers. Many industrial processes generate vapors, fumes, or mists laden with toxic substances that must not be inhaled by production workers: filtration allows for their reduction and protects their safety.

Secondly, there are economic reasons. In several industries, during production, there are valuable substances – precious metal dust in goldsmith workshops or solvents in printing processes, for example – which tend to disperse as particulate matter. Filtration allows them to be captured, recovered, and reused in the production process. Conversely, there are also dusts and particulates that, by depositing and accumulating on industrial machines, damage them; filtration, in this case, allows their presence in the air to be reduced, thus safeguarding the operation of the production equipment.

Thirdly, but no less important, there is an ecological reason: various contaminating substances, by-products of industrial processes, must absolutely not be released into the environment, as they could cause serious pollution. Filtration allows for their capture and the emission of clean air, accumulating the contaminants where they can be disposed of safely.

Precisely for the third reason just mentioned, precise rules and regulations exist and are constantly updated that regulate, at the local level and according to the type of productive activity, the maximum acceptable thresholds for each type of particulate and pollutant, and therefore what type of filtration system must be used to reduce them.

Filtration is therefore a precise duty of the company, established by law in terms of methods and extent.

This state of affairs naturally leads companies to orient their choices in the field of filtration based on two criteria. The first, inevitably, is strictly technical: each type of contaminant, and each type of production process, requires the application of different technologies to achieve effective abatement. The second is instead a very conservative criterion: that of orienting each choice to the minimum threshold required by the regulations, aligning oneself with that result.

It is perfectly understandable, on the one hand, that a company aims to contain costs, and that the filtration system can represent a considerable expense – between construction and maintenance – that one wants to control. But on the other hand, especially if well managed, the expenditure for the abatement of polluting particulates can become a real marketing investment, especially at this historical moment.

More and more people are re-evaluating ecology as an important element in the evaluation of a company, and consequently companies that demonstrate that they go beyond the legal obligation in the defense of the environment are beginning to acquire a strong leverage on the image front. Showing awareness of the importance of ecology, today, can be (besides being a good idea in absolute terms) even a competitive tool. For this reason, it may be useful to consider even more performing systems than the minimum necessary.

Bruno Balducci srl not only produces, but also designs its own air filtration systems: for this reason we can customize each filter according to the application conditions, the sector of use and the filtration efficiency required by the client, up to the possibility of creating absolutely unique and custom-designed products for the particular needs of a company.

In addition to this we can custom build for you components and spare parts for older systems, for which it has become difficult or impossible to find original spare parts on the market: our service includes, in addition to design and production, all the operations of maintenance necessary to maintain your filtration devices in perfect efficiency.
