C-Series
2.5 Ton to 15 Ton Air Over Oil Presses
These C-Series Units 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. These 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 presses are a more cost effective and energy efficient alternative to the Full Hydraulic Press.
