As fast as a pneumatic cylinder and as strong as a hydraulic one

How they Work
Pneumo-hydraulic cylinders integrate two components in a single actuator: a pneumatic cylinder and an air/oil pressure intensifier.
The pneumatic cylinder is located in the lower part of the unit and allows for rapid approach to the workpiece.
The air/oil intensifier is located in the upper part of the unit and allows the pressing of the piece with high force (up to ten times greater than the force that would be obtained with an air cylinder of the same bore).
Pneumo-hydraulic cylinders can replace hydraulic cylinders, eliminating the need for a dedicated hydraulic power unit.

With 2 models and 9 sizes (thrust force from 5 kN to 419 kN) the pneumohydraulic power units of the AP and AX series offer high productivity at low costs.

They use compressed air as the only power source.
The approach stroke is completely pneumatic, fast, efficient and inexpensive.
Once in contact with the piece, the ingenious air-oil multiplier system develops the force necessary for the actual pressing.

Pressings, fittings, deformations, assemblies.
Operations that the cylinder performs easily, efficiently, combining the best of pneumatic and hydraulic technologies.

The Advantages

High quality hydraulic and mechanical seals: these cylinders are built to last.

With pneumatically controlled approach and return and hydraulic pressing stroke, they guarantee reduced cycle times for unrivaled yield.

The pneumatic/hydraulic separation limits consumption to the pressing phase only, only when needed.

The AP Series

The hydropneumatic cylinders of the AP series have an linear .
