(1) if the product requires a purity level of 100, select a laminar flow type; If the product requires a purity level of 1000-100 000, choose the type of turbulent flow.
(2) reduce vortex currents and avoid pollutants from outside the working area entering the working area.
(3) in order to prevent secondary dust spreading, the air velocity shall not be too high. The return air of the turbulent clean space shall not be located at the top of the working area. It is advisable to position the inverse vents evenly on the floor or under the side walls.
(4) the flow of air in the working area shall be uniform and the flow rate shall be in accordance with the requirements of technology and hygiene; The flow of clean air shall surround the working area as much as possible so that the pollutants can enter the outlet of the return air before spreading; Oh, my god.
(5) in the arrangement of the operating equipment, a certain distance shall be left to permit the arrangement of air inlets and returns and the smooth passage of air: the influence of high equipment on the arrangement of air flow shall be taken into account in the design of air flow management.
(6) a clean workbench shall not be located in a clean room with a laminar flow of air. When installed in a clean room with turbulent flow, it should be located on the windward side of the air flow in the working area to improve the cleanliness of the air in the room.
(7) if there is a drawbar in a clean room, it should be located on the windward side of the air flow in the working area in order to reduce the pollution of the room.
