This customer is engaged in the field of new energy battery manufacturing, and uses a large number of filters of different class with unconventional sizes. For example, the F9 filter element has a length of 1.2 meters. According to the test of HVAC general ventilation filters, the existing HVAC filters in the market are generally used for ventilation, and the length and width are not more than 700mm. According to the HEPA test, the efficiency of the test rig is higher than that of the F-class filter. After all, the scanning method is used for leakage detect of HEPA filters.
Currently, testing rigs on the market is either designed and manufactured according to ISO 16890 and ASHRAE 52.2, which can test general ventilation filters, but can't test high-efficiency (HEPA) filters. Either designed and manufactured according to ISO 29463, which is mainly used for testing high-efficiency (HEPA and ULPA) filters. The lower limit of the tested filter efficiency is E10.
My filter classes are between F6 and H14. Do I have to buy 2 testing equipments?
After all, it is a big investment to buy two testing equipment at the same time. Equipment maintenance and personnel workload will increase. These costs are allocated to each filter element. In some new enterprises, there are many varieties of filter element, and the sales volume is not stable. How to rationalize the investment of testing equipment is also one of the factors to be considered related to the comparative advantages of filter products.
Solution
Our engineer carried out many experiments, and the improvement scheme based on the SC-L8023 automatic scanning test system was finally determined. Expand the testing efficiency range to meet customer needs.
The maximum size of the filter can be tested is 1220mm×1220mm×400mm. After calculations, the engineers determined the scheme, improved the hardware and software, and after a lot of experiments, the product was formed.
Finally, the efficiency range was extended to F9, the air volume was increased by 20%, and the customer's F9 filter with a length of 1.2m could be tested. In order to make it more convenient for customers to use, we have also added tips for scrapping and replacing consumables-medium efficiency of air intake and high efficiency filters.
Field Application
At present, the equipment has been delivered to the customer for use and has passed the customer acceptance.
After 15 days of trial operation, the test system has passed the customer acceptance.
