    Air filters Max pressure advised



    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.
