A worn diaphragm assembly can disrupt the controlled flow of air or fluid in a pneumatic or vacuum system. This aftermarket replacement part references the Doosan catalog and carries the part number DWMB91H20-04380.

A common failure consequence is loss of pressure regulation, leading to erratic performance or system stalling.
