The controlled structural variations of Absolute HEPA filter applications may be similar if we analyze the precision synthesis. The design of cutting edge Absolute HEPA filters further reveals that their self-assemblies are remarkably sensitive to primary chemical structures. This will lead to highly diverse and stable nanostructures even though the feature sizes around 10 nm or smaller in the bulk. Absolute HEPA filters should provide a versatile platform for engineering needs in filtering practice. There is no doubt that the findings are not only scientifically intriguing in understanding the physical principles of absolute HEPA filter applications but also technologically relevant with microelectronics.
This is largely because the units of Absolute HEPA filters are situated outdoors. Ultrafine and submicron particles can be absorbed with the help of Absolute HEPA filters since they are possibly highly related with respiratory and cardiopulmonary diseases and syndromes as well. Many studies have shown that an ionizer operated upstream of a ventilation filter could greatly enhance the particle collection efficiency in absolute HEPA filter applications. This is because Absolute HEPA filters will not affect the pressure drop. However, most of these studies are based on one single fiber material and does not develop any comparison among different Absolute HEPA filters.
That is why we need to investigate into the influence of the fiber material and filter class of Absolute HEPA filters in terms of the enhanced efficiency. The influence of absolute HEPA filter applications is also considered. The experiments concerning Absolute HEPA filters are conducted in a full-scale filter test rig that has one hundred percent air re-circulation. To be more specific, seven filters are made of three types of fiber materials and a mobility particle size has been utilized to count ultrafine and submicron particles. This is true in the upstream and downstream air flow inside Absolute HEPA filters. In the chamber test, a charged synthetic filter can be mounted in the air re-circulation system since each test plenum consists of one or more filter boxes.
Thus, we need to take into account of the reduction pieces, connecting ductwork, and circular ducts of absolute HEPA filter applications without any doubt. These factors will help us to regulate the flow of air through the filters since the duct fans can be sized inside Absolute HEPA filters. By doing so, we can also overcome the predicted total pressure drop at the end of the experiments. This is because the inlets of the units are protected from large objects, tree litter and precipitation. The airflow inside Absolute HEPA filters through the systems can be adjusted to a standard rate through the filters.
