Greetings,
I've got a question, so I have this air handling unit that contains 2 filters (Galvanized frame G4 and Bag filter F7) attached together.
At what pressure differential should I set up the manometer, for the alarm of the filter contamination?
F7 Pressure Max pressure advised is 200 Pa
And the G4 is 140 Pa
Do I add the two values together? 340 Pa?
Available for more information.
Hi
I wouldn't recommend using one manometer across both bag and panel filters. Others however may have a different opinion.
Ideally, as the panel and bag filters have different characteristics and pressure drops you need to use two manometers, one for each type of filter.
Agreed ^^^^^
Use one manometer per filter type/bank.
The panel filter collects most of dirt so could be changed several times before the bag needs replacing.
I totally agree with you, nice advice.
