Why Test Air Shower Differential Pressure
Why Test Air Shower Differential PressureWhy should we test the differential pressure of the air shower room, but also from the working principle of the air shower room, the air shower room as installed in the clean room and non-clean room between the local purification equipment, when people and goods need to enter the clean room needs to be blown through the air shower room to remove the dust carried. The reason why the air shower room can achieve the effect of purification is that the centrifugal fan will be a static pressure box through the high-efficiency filter air, and then through the nozzle to form a jet of airflow, with a certain wind speed will be the person and the dust on the surface of the object to take away, to achieve the effect of clean.It is noted here that the high-efficiency filter plays a vital role, the high-efficiency filter controls the number of dust particles as well as sedimentation bacteria and planktonic bacteria, etc., determines the operating effect of the air shower room purification, so the replacement time for the high-efficiency filter is very important to grasp. High-efficiency filters in normal use of the situation, the service life can reach more than one year, installed in the air shower room of high-efficiency filtration of the front section of the primary filter protection, the service life will be extended. HEPA filters need to be replaced based on accurate running time records and cleanliness and airflow. A simpler way is to judge the replacement of high-efficiency filters by the pressure difference. For high-efficiency filters installed in the air shower room, when the resistance of the filter is greater than 350Pa, the airflow speed on the air outlet surface cannot reach more than 25m/s, thus affecting the clean effect. |
