ADDITIONAL INFORMATION:
Filter-regulator, or "piggybacks" combine the functions of both a filter and regulator. Piggybacks are compact and most effective when space is a constraint. Piggybacks can be ordered with different filter elements and can be modified with different springs, depending on the filtration and air regulating requirements.
