ly by the effects of the emissions on humans. A distinction is made between whether they are inhalable (I-fraction) or alveolar (A-fraction). A-fraction pollutants can pass between the blood-air barrier, which separates the air- filled cavities of the pulmonary alveoli from the blood in the capillaries. DIN EN 481 defines statutory limit values.
To meet the regulations of various countries, it is often necessary to use extraction and filtra- tion systems to clear the air of pollutants.
Eliminating Particles In order to eliminate air pollutants, it is
not enough to only provide ventilation in the manufacturing environment. The use of effi- cient extraction and filtration technology is mandatory according to the Employ- er’s Liability Insurance Association. There is a wide variety of avail-
able extraction and filtration systems. Selecting the appropriate system de-

basis for subsequent high-grade filtration, which defines the overall efficiency of the sys- tem and the residual pollution in the recircu- lated air.
Besides removing unpleasant odors, the
goal of air purification is to eliminate haz- ardous airborne substances. Air purification can play a major role in determining which companies survive in the highly-competitive electronics manufacturing space, as air quali- ty has a significant impact on employee well- being and product quality.

pends on the type and volume of pro- duction, the use of automated, semi- automated, or manual production equipment, as well as any require- ments for mobility and flexibility. State-of-the-art extraction and filtra- tion units can process ambient air so well that the cleaned air can even be recirculated into the work area. Collecting the airborne pollu-
tants is a significant part of the task. Close proximity to the source of emis- sion is critical. This not only captures particles before they reach the ambi- ent air and build up on equipment, but also minimizes the cost of the ex- traction system. The larger the dis- tance between the source of emission and the collector, the higher the suc- tion capacity of the machine needs to be. This has a huge impact on overall energy consumption. There are many different kinds of
collection elements, which are the fit- tings on the ends of the extraction arms. These are designed to ensure op- timal absorption of the emissions in different processes. Depending on the type and the amount of pollution, as well as airflow principles, users can se- lect from a wide variety of elements. Complete enclosures are also available. Choosing the proper collecting el-
ement is key to the quality of the en- tire extraction and filtration system. The level of pollutant capture is the
