Today I would like to introduce a new type of material to you, which is the clean room filter material produced and developed by the company.
Let’s take a closer look below.
The first index to evaluate the cleanliness of industrial gases is purity, and the second is the number of dust particles and bacteria entrained in the gas.
The dust content in the air of various commercially available bottled nitrogen is 1140 to 265 particles/L (0.3μm).
The dust content in the gas output from the pipeline of the gas generating station is greater than 600 particles/L (≥0.3μm).
The dust content of production gases is generally required to be no more than 3.5 particles/L (≥0.5μm).
So a dust filter must be installed.
For gases used in the pharmaceutical industry, the filters used at the end of the pipeline mostly use clean room filter materials. The pore sizes of the filter membranes are different, including 0.22μm, 0.45μm, 1μm, 3μm, 5μm, etc., resulting in different degrees of purification. High-efficiency air filters can reach level 100 for dust with a particle size of ≥0.3 μm, and are currently used as the main means of terminal purification.
High-efficiency air filters are available in flat, cylindrical and pleated types, and are divided into several models according to different gas flow rates.
The clean room filter material produced by Suzhou PTFE filter membrane manufacturer by mechanically stretching PTFE material can ensure complete retention of impurities such as bacteria and has a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
