What Should We Know After Finished Install HEPA Filter
What Should We Know After Finished Install HEPA Filter
HEPA Filter structure:
Frame, gasket, filter media, spacer, glue, hot-melt spacer,
protective net, PU foam.
The ULPA/HEPA/EPA filter life and maintenance
A: General speaking, if the filter finally pressure is double or triple than
primary pressure, it is time to change a new air filter.
B; please check and test the area clean class, the test date should satisfy
with workshop require.
C: if you often change the pre-filter or secondary filter, it can prolong the
HEPA filter life.
Problem and solution:
Problem | Reason | Solution |
There is some particular when you scan | 1:the surface of media has particular 2: the frame have small aperture. | 1: with the air blow the filter for a while, the particular will take off 2: repair glue |
After installing in clean room, we find there air leakage | 1; the gasket was broken 2: the installation frame or air hole has small leakage | 1: change the gasket. 2: check the install frame and air hole. proof it with glue.
|
After finishing installation, the clean room system can not reach requirement in test. | 1. Clean room inside is sub-pressure. 2. The system pressure is not enough. | Increase air flow in system |
Find there is a lot of air leakage | The filter is damaged | Change filter |
The air system supply enough rating air flow, but air velocity is still small | The filter reached its rating capacity for dust holding | Change filter |
