Air is leaking out of this (circled in Red). What does it do? Is it replaceable by itself?
1. Item circled in red is a pressure regulator, very likely it is HWH part number AP23204.
2. Regulates pressure?
3. Perhaps, or may be repairable. Do a Google search for
AP23204 and see what turns up. HWH might sell them, or FOT, or MOT?

Thank you very much for this info - much appreciated
It is the pressure regulator and vacuum generator for one of your slides. Can turn the shut off valve at the bottom of the picture to stop and deactivate the slide bladder. They are field repairable and if it was to cause an overpressure it could damage the bladder. Outlet pressure should not be above 15 psi.
