Our company substituted hoffan #75 air vents for vacuum breakers.  This is on a steam coil in a Trane air handler.  What problems could I expect to see if any?

    The question

    really is, what is the steam pressure the air handler runs at?  If the Hoffmanns are rated for that pressure, I don't see why there would be a problem.  The 75 is rated for 3 psig; the 75H is rated for higher pressures.
