    Is it corrrect that allowable pressure drop for a liquid filter/drier for r-22 is 2 degrees F or 3 psi?Actually is this the same for r-134a for said chiller too?

    We had a thread on that, so do a search.

    I think the result of that discussion indicated that by the time you get to 2F you have a larger drop than 3 psi, in fact, I think it was more than 10 psi.

    It might have been in the Pro section....
