In lower cleanroom classes (ISO 9 \u2013 ISO 6) the number of air changes is controlled. In more sensitive clean rooms, the surface velocity is kept within certain limits instead of the number of air changes. The people in the room and the amount of particles originating from the process should be considered when making all calculations.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a; font-size: 105%;\"><strong>air flow model<\/strong><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a;\">Three different air flow models can be mentioned when designing a clean room:<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a;\">Unidirectional (laminar): Air moves straight, vertically or horizontally in an unobstructed path.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a;\">Non-unidirectional (turbulent): Air flow creates an irregular, non-parallel flow.&nbsp;<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a;\">Mixed (kar\u0131\u015f\u0131k): Hava ak\u0131m\u0131 odan\u0131n farkl\u0131 b\u00f6lgelerinde laminer, farkl\u0131 b\u00f6lgelerinde t\u00fcrb\u00fclansl\u0131 \u015fekildedir.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a; font-size: 105%;\"><strong>High efficiency filtration<\/strong><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a;\">Generally, HEPA filters are used in clean rooms, which can capture 0.3 micron particles with 99.97% efficiency. HEPA stands for high efficiency particulate air. In addition to the diffusion filtration mechanism, different mechanisms are also used in HEPA filters. Although the filters can be located on the air handling unit, they are mostly installed in the HEPA filter boxes above the clean room to ensure the cleanliness inside the room.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a; font-size: 105%;\"><strong>Chamber pressurization<\/strong><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #27282a;\">Clean rooms are generally min.
