| Filter classes | E10~H14, 85%~99.9993%@0.3μm |
| Test aerosol | DEHS |
| Particle counter | 8 channels, 0.3,0.5,0.7,1.0,2.0,3.0,5.0,10.0μm |
| Scan speed | ≤10 cm/s |
| Sampling probes | 1 or 4 probes, 66*15mm |
| Compressed air supply | ＞7 kg/c㎡ |
| Power supply | AC 380V, 50Hz |
| Dimensions | 5700*1800*1800 mm |
| EN 1822-4 / ISO 29463-4 | Local leakage determination for applicable finished EPA, HEPA and ULPA filter classes. |
| EN 1822-5 / ISO 29463-5 | Overall filter-element efficiency or penetration measurement at the required particle size or MPPS. |
The test system supports the applicable procedures according to its configured aerosol, particle-measurement range, airflow and scanning arrangement. EN 1822 and ISO 29463 do not certify the cleanliness class of the room in which the filter will be installed.
Scope Boundary
Overall efficiency, local leak scanning and installed-system integrity testing are different test tasks. Factory testing of a finished filter does not verify possible leakage through the housing or installation after the filter is installed.
