The AH-Series Hydro-Pneumatic Press, or sometimes referred to as an “air over oil” press, is an alternative solution to conventional hydraulics presses by providing a cleaner, quieter, and more cost effective solution to a wide variety of pressing and forming applications. This unit provides a rapid low force approach stroke with a self-contained hydraulic intensified power stroke all in one complete package.
You can purchase individual intensifier cylinders separately. See our B-Series Intensifying Cylinder for more information.
Applications: Riveting, Crimping, Punching, Swaging, Trimming, Marking or Character Stamping, Assembly, Notching, Joining, Forming, and Fastening.
