Shandong Xinli DC FFU filters the interior of the air inhalation through the air filter at the top of the dust-free workshop, and the clean air is sent out in a uniform wind speed, so that the clean and sterile purification effect is achieved.
The filter forms resistance to airflow.The filter accumulates dust and the resistance increases. When the resistance increases to a certain value, the filter is scrapped, as shown in the figure below
(1) In the clean room standards of various countries, the number of air changes in non-unidirectional flow clean rooms of the same level are not the same.my country's \"Code for Design of Clean Workshops\" (GB 50073-2001) clearly stipulates the number of experience air changes required for calculation of clean air supply for different levels of non-unidirectional flow clean rooms, as shown in the following table:
The definition of clean room is a room where the concentration of airborne particles is controlled.Its construction and use should reduce indoor induction, generation and retention of particles.Other relevant indoor parameters such as temperature, humidity, pressure, etc. are controlled as required.A measure of clean room cleanliness: the degree of cleanliness distinguished by the number of particles of a certain particle size per unit volume of air.Cleanliness level:
The nylon mesh primary filter is generally used in the primary filtration system of central air conditioners and household air conditioners. It has the advantages of large air volume, low resistance, repeatable cleaning, and long service life.The nylon mesh filter adopts a lightweight plate structure, a reusable metal aluminum frame, wear resistance, long service life, high strength, good comprehensive use effect, simple and beautiful filter structure, low initial resistance, strong dust resistance, and It is cleaned and reused many times, easy to replace and safe, and users can operate by themselves, which is simple and convenient.And non-standard customization can be made according to customer needs, and it can also be used in multiple groups with buckle/handle interconnection, which is easy and safe to replace.
