FAQ

Frequently Asked Questions

Technical answers to common questions about Hard Hub Disc Filters.

A Hard Hub Disc Filter is a metallic filter element with a rigid machined hub that provides a secure metal-to-metal seal and high mechanical strength for polymer melt filtration.

Yes. Hard Hub Disc Filters are designed for multiple cleaning cycles. Depending on the contamination and process media, they can be cleaned using chemical cleaning, ultrasonic cleaning, thermal cleaning, or automated high-pressure cleaning systems, helping extend filter service life and reduce operating costs.

Yes. Purofiltec manufactures replacement Hard Hub Disc Filters compatible with various polymer filtration systems and OEM equipment, based on customer drawings and specifications. We can even make housing for Disc Filters and cleaning Machines.

Yes. Purofiltec designs and manufactures Automatic Disc Filter Cleaning Machines for efficient and repeatable cleaning of metallic disc filters. The system uses high-pressure water jets to remove polymer residues and contaminants while minimizing manual handling, reducing cleaning time, and extending filter life.

Hard Hub Disc Filters are available with filtration ratings from 10–80 µm, depending on the required polymer melt filtration application.
