1. How to choose the right filter bags for your company?
Cause every filter has its own characteristics and parameters, so
when we choose filter material for filter bags, we have to know the
following parameters:
(1) Working temperature ( Continuous / Peak)
(2)Measurement of filter bags
(3) Gas’ chemical properties
(4) Working pressure
(5) Emission concentration
2.How to assure the product quality?
If you need , we can offer the sample for you, after your
confirmation, we can produce the products according to your
requirement.
3.How many times can I clean and reuse a filter bags?
Filter bags are designed for one time use. Attempting to clean a
filter bags will stretch the material. Maybe some holes will get
bigger and allow dust to get through. In our company, most of the
fiber is imported, we use the best raw material to ensure the
quality of filter cloth bags. Normally we can offer 2 years,
3years, 4years bags life time and even longer by your requirements.
4.What shipments are available?
Normally, we ship goods by sea,air or express. Special requirement
can also be acceptable.
5.Sample rule
We offer you free samples as your requirement.If you are the first
time to cooperate with us ,the postage should be paid by you. When
you place the order ,we will return back to you in the next
cooperation.
