AFD70

The AFD70 Series Passive Device is a simple, low-cost unit for surface finishing applications. Using a low friction cylinder and linear rail technology this device delivers outstanding performance.

Fitted with a manual or electrically controlled pneumatic regulator, the 70 Series can make quick work of many surface finishing applications.

The 70 Series can be configured as either an AFD71 single acting with only positive force application, or an AFD72 double acting with positive and negative force capability.

The AFD70 Series Passive Force Device was designed as an inexpensive alternative to the 1000 Series. In some applications the AFD70 can provide comparable performance to the AFD1000 at a much lower cost. The simplicity of the 70 Series does, however, require more integration effort from the end user. The 70 Series is a very simple and rugged device, that incorporates several innovative features. The 70 Series uses glass cylinders with graphite pistons, and linear ball bearings to greatly reduce operating friction. It has the same physical dimensions as the 1000 Series, and the same bolt patterns. This means that all of the AFD1000 mounting options are available and that most of the process equipment will bolt right up.

The AFD70 Series requires the user to supply regulated pressure to control the force output. An AFD71 requires one regulator and the AFD72 needs two. The force output resolution is highly dependant on the regulator accuracy. The regulator can be manual or electrically controlled based on the application. If a constant force is required and the orientation does not change, a manual regulator is sufficient. If the force and / or orientation changes during the process, then an electrically controlled regulator is necessary. This means that the rpocess equipment weight must be compensated for, which requires calculation of the regulator pressure.
