FAQ – Frequently Asked Questions

Q1: What does a 40µm PE disc filter remove?
It filters medium-sized particulates like dust, fibers, or suspended solids in gas, air, or liquids.

Q2: Can this filter be reused?
Yes. It can be cleaned and reused using water, alcohol, or mild detergent, depending on your application.

Q3: Is the PE material safe for sensitive systems?
Yes. PE is non-toxic, chemically inert, and suitable for clean applications including medical and lab use.

Q4: What is the temperature limit for PE filters?
Generally suitable up to ~80°C. For higher temperatures, PTFE or metal alternatives are recommended.

Q5: Can DALON customize this disc filter?
Absolutely. We can produce filters in custom diameters, pore sizes, and shapes per your exact design.
