Electronic clean workshop is a part of the enterprise with particularly large capital investment. After the completion of the construction of clean workshop, whether the design purpose can be achieved (to meet the requirements of product process production and GMP) needs to be confirmed by practical testing.

Cleanliness is a particularly important key factor in the testing of electronic clean room standards. If the cleanliness test of the electronic clean workshop is not qualified, when some cleanliness test is not up to standard, some of the local space, but also the whole electronic clean workshop project. Although the requirements of process production can be reached through rectification, debugging, cleaning, etc., it often wastes a lot of manpower and material resources, delays the construction period, and delays the process of production efficiency. There are often causes and shortcomings that can be completely avoided before testing.

In some small purification level requirements are not too high on the construction of electronic clean workshop, some enterprise units in order to save money, casually find no qualifications or experience of small companies. The competition among some purification engineering companies is fierce. In order to get the project, some construction units give a lower quotation in the bidding. In the later construction, the use of some units do not know much about the situation, jerry-built, the use of low power air conditioning ventilation compressor units, so that the air supply power and area do not match, resulting in unqualified cleanliness. There is another reason, is that after the design and construction of the unit, and increase the new requirements and purification area, which will also make the original design can not meet the requirements, this congenital defect is difficult to improve, to avoid in the engineering design stage. An industry insider also found that individual construction units in the acceptance, pre-blocked part of the air outlet, in order to muddle through.

In the application of high energy efficiency filter in electronic clean workshop, Hejie technology electronic purification project in strict accordance with the provisions of the cleanliness of 100,000 or more than 100,000 level of air purification treatment, should use the first effect, medium effect, high energy efficiency filter of three levels of filtration. And in the verification process of maintenance of a clean project, we have found that an electronic clean workshop project uses sub-high energy efficiency air filter instead of high energy efficiency air filter on the 10,000 level of purification, resulting in unqualified cleanliness. Finally replaced the high energy efficiency filter, to meet the requirements to meet the standard.
