Q 17 . How can we decrease the cost effectively for “factory” when using filters and housings？

We suggest you to check all the details as following in order:
1.Find out the using list of filter rating indication.
2.Find out if it is possible to use certain rating indication.
(especially from nominal rating 1um to 50um)
3.Do not over rely on the data in the catalogue because all factories test filtration systems by water.
You still have to buy certified and replaceable filters and have to do on-line test.
The most important is that finding out a company willing and able to solve all the problems for you.
