Ingersoll Rand P39344-600-VS 1/2-Inch Filter-Regulator Piggyback, Black
ARO-Flo Filter-Regulators, or "Piggybacks" combine the functions of both filter and regulator. Piggybacks are compact and most effective when space is constrained. Piggybacks can be ordered with different filter elements and can be modified with different springs, depending on the filtration and air regulating requirements.
