2.5 Ton to 15 Ton Air Over Oil Presses

These air-hydraulic presses come in four sizes ranging from 2.5 ton to 15 ton capacity. Standard features include a full length power stroke, 2.0″ adjustable downstop, and an anti-rotation ram guide. The heavy duty C-frame units can be mounted on a floor stand or a bench top machine base. They also have an adjustable force regulator and speed control regulator.

Our C-Series Air-Hydraulics Press is a more cost effective and energy efficient alternative to a full hydraulic press.

C-Series Videos and Animation

When the air-hydraulics press valve is energized, air enters the booster cylinder extending the booster ram. This transfers the oil into the ram cylinder, extending the cylinder rod down. Unlike other brands, hydraulic pressure is maintained throughout the entire stroke, not just a limited part of the stroke. When the valve is de-energized, the ram retracts to full home position. Take a look at our Air Hydraulics Presses in action below.
