Introduction
Test items:
Integrity (whether the damage of the filter, filter joint, end cap adhesive with or without defects);
The maximum bubble diameter of the first bubble point pressure filter;
The average pore size of the bubble point pressure filter;
Filtering accuracy (βx ≥ 20 corresponds to the reference value).
Test objects:
Oil filter material and air filter;
Oil filter and air filter;
All filter components of the chip filter and filter.
Application
Product development and quality control department monitoring center
Quality inspection and supervision institutions
Filter users and filter manufacturers
Features
◆ Filter element and filter material is easy to install;
