Description of one-circuit systems
The one-circuit system is used for frames up to approx. 150 cm length.
With the one-circuit system, clamp positioning must correspond with the inside edge of the frame.
The one-circuit system uses a single control box, with two air outlets. One is connected directly to the first clamp, the other to the clamp diagonally opposite, in order to supply compressed air to both sets of clamps. They are also linked by a pneumatic coupling in the other diagonal corner.
