A Dedicated Standard 199 Test Rig Eliminates Guesswork
Standard 199 testing compares dust collectors based on true operating conditions and real world performance data on emissions, pressure drop, compressed air usage, energy consumption and emission readings. The standard applies to industrial dust collectors that use pulse cleaning to recondition the filter media so the collector can continue to operate. Armed with this comparative data on operation, energy costs and particle emissions, you can make more informed long-term decisions to reduce maintenance, consumables and disposal costs.
Standard 199 Testing Stages
- Stage 1: Initial dust loading. Feed dust into the collector at the specified rate, without pulse cleaning, until the system reaches the specified differential pressure.
- Stage 2: Initial dust loading with on-demand cleaning. Begin on-demand pulse cleaning while continuing to feed more dust at the same airflow. The high and low differential-pressure set points determine the cleaning interval. Pulse cleaning is the most common filter-cleaning method that the pharmaceutical industry uses.
- Stage 3: Dust loading with continuous cleaning. Maintain the airflow and dust feed and continue to pulse-clean the filters at routine intervals for 24 hours or until the system reaches the specified maximum differential pressure.
- Stage 4: Final dust loading with on-demand cleaning. Test the final dust loading with on-demand cleaning by maintaining the airflow and dust feed. As with Stage 2, the high and low differential-pressure set points trigger the filter cleaning, the frequency of which varies depending on the system’s performance and pressure buildup.
- Stage 5: Upset condition. Maintain the dust feed while suspending pulse cleaning to mimic how the dust collector would perform in an upset condition.
- Stage 6: Post-upset condition. Replicate the downtime cleaning process to simulate a post-upset scenario to return the system to normal operation.
