Finding a Baghouse Ventilation Air Leak Before Damaging HEPA Filters

Finding an air leak in a baghouse ventilation system before damaging HEPA filters video thumbnail

In this Tip of the Month Video, IAC Engineer Luis Castano, explains that just like baghouses, the differential pressure on HEPA filters for toxic dust must be monitored. However, if your baghouse has a leak, by the time the HEPA filter monitor indicates a high differential pressure, the HEPA filter’s performance has already been compromised, potentially causing a very expensive problem. Watch the full video below to find out how to detect a leak and prevent this problem.


Video Transcript:

Hi, my name is Luis Castano with IAC’s tip of the month. If you remember last month, we discussed the situation with monitoring differential pressure on your baghouse and the differential pressure on your HEPA filters in case you’re dealing with toxic dust. It becomes very important to monitor both, but then the question came up, by the time the differential pressure on the HEPA filter is a problem, then the HEPA filter is affected.

Now if this system is huge, and HEPA filters are handling a lot of volume then it becomes a very expensive problem. So, one thing we can do is put an emissions detector on the duct between the baghouse and the HEPA filter that will warn you if there’s a problem in the baghouse before you’ve destroyed the HEPA filter. By the time the HEPA filter raises in differential pressure, then the HEPA filter is pretty much done.

So, one way to avoid that is to put an emissions detector after the baghouse which will trigger as a signal that you have a problem before the HEPA filter. If you want to discuss this in detail, please contact IAC and we can help you. Thank you!
