Product Description
NF SeriesNF series filter cartridges use nano-sized fiber as filter media, with high porosity and stalbe pore size.Each filter can be used for integrity test.Nano fiber membrane SEM
Features and benefits- Nanofiber membrane with our own independent intellectual property rights, has better poriness and higher flow rate, which is almost three times better than normal pleated filter cartridge.
- Absolute filter cartridge: stratified gradient structure; 99.9% interception efficiency; measurable bubble point value.
- Back-washed with an acid base solution of 1-14pH, and still remain the initial performance. Greatly extend the service life.
- DFA 21 CFR170-199, EC Number1935/2004 certificated.

ApplicationsElectronics, food&beverage, pharmaceuticals, process water. Typical case
Ozone water filtration problem(about chemical resistance and flow rate) in Panel plant
Company D is a global LCD panel company with several product lines, such as covering 6th generation line, 8.5 generation line, etc. It has several production bases in Taiwan and mainland China.
During the contact with Company D, our salesman found that in order to increase the flow rate of washing water, the customer rushed into the ozone water at the process node, causing the filter core used by the customer to be corroded within 2 days.
After understanding the problem, our company immediately communicated with the customer and sent a technical team to visit. It was learned that the corrosion-resistant PTFE material could not meet the flow rate requirement. Although PES can meet the flow rate requirement but is not resistant to corrosion.
Therefore, our company had proposed a high-throughput,high-blocking,corrosion-resistant product (nano PVDF material) as a solution. After the customer compared, he thought we could try it out.
As a result, our filter element did not detect corrosion for one month after ensuring flux and interception rate, and the customer's product yield also met the requirements. The customer was very satisfied with the verification results and quickly reached the supply agreement for the filter element.
The result is that our filters have been used for a month and weren't detected any corrosion on the premise of meeting all the requirements. The customer was very satisfied with the verification results and quickly reached a supplier agreement for the filters. |

FAQ
1. How long is the service life of the filter cartridges/How much is the filtration capacity?Take ink filtration as an example.
1) Different types of ink, viscosity, contamination and grinding process affect the service life of the ink.
2) The different configurations of filter cartridges affect the life of the filter cartridge, whether there is pre-filtration or not, whether pre-filtration is balanced or not.
2. Why does some filter cartridges have a problem of fiber shedding?1) Chemical resistance is not good;
2) The filter membrane
such as polypropylene (PP) stretched microporous membranes and polypropylene (PP) fiberized deep filtration membranes themselves have the risk of fiber shedding;
3) Fibers caused by wire drawing during the production process, and no rinsing.
Solution: We can add our anti-fiber shedding layer or use other filter membrane made by special processes.
3. What is the MOQ?/How can I get a sample?/ What's the sample fee?/How long wiil it take?
We don't have the MOQ, but the price depends on the quantity.
Generally a small amount can be free, but the clients need to pay their shipping costs.
If the amount is big, or the unit price is very high, we can give the clients some discounts.
Please confirm with us the model you'll purchase and prepay the sample fee.
We will send out the sample within 3-5 working days afetr receiving payment.
