Cleanable filter media

Test method for filtration characterization of cleanable filter media






















ISO 11057 Sequence of the standard test phases

Measuring phases

Conditions

Determination of clean-gas concentration

Phase 1: conditioning

30 loading cycles with differential pressure controlled pulse-jet cleaning and a cleaning set point of 1 000 Pa

yes

Phase 2: ageing

2 500 pulse-jet cleaning cycles at an interval of 20 s each

no

Phase 3: stabilizing

10 loading cycles with differential pressure controlled pulse-jet cleaning

no

Phase 4: measuring

30 loading cycles but at least 2 h measuring time with differential pressure controlled pulse-jet cleaning and a cleaning set point of 1 000 Pa

yes

Phase 5: optional measuring

2 h loading cycles with raised cleaning set point of 1800 Pa

yes
