I wonder how much you know about clean room FFU filter membranes? Today I will take you to learn about this material.
FFU is the English abbreviation, the full name is FanFilterUnits, the Chinese meaning is “fan filter unit (unit)”, also known as air filter unit.
The fan inhales air from the top of the FFU and filters it through primary and high-efficiency filters. It provides high-quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels.
The FFU implementation standards of various purification engineering companies are slightly different. The common indicator in the industry is: the clean air filtered by the FFU filter membrane in the clean room is sent out at a uniform wind speed of 0.45M/S±20% on the entire air outlet surface. But the stability gap is huge.
After on-site testing, international brands generally find it difficult to adapt to “Chinese environmental factors”. Although the quality is generally higher than that of domestic companies, the stability test after one year is generally not ideal; and the engineering quality of most domestic low-end brands is also relatively low. Not satisfactory.
The purification engineering industry began to pay attention to the two-way acceptance standards of product quality and stability, and gradually used on-site testing data (previously, most of them relied on industry reports) to more truly reflect the cost-effectiveness of the project. ptfe membrane manufacturer specializes in the production of clean room FFU filter membranes, with A full set of advanced production equipment and technology, as well as an advanced clean room and an independent composite slitting workshop, ensure the production quality of ptfe membrane; the product materials produced are all imported raw materials, with high uniformity, stable performance and good breathability , the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
