PNEUMATIC

Principle operation pneumatic sliding door;

The operation of a sliding door is the most basic of all door types, the guiding is realized by a track in which the rollers connected to the door leaves are running.
The movement of the door leaves (A) is by means of a linear pneumatic cylinder (B) which is connected to one of the door leaves (primary). The synchronization between the primary and secondary door leaf is realized by means of a synchronization cable or belt (C) or by means of a spindle (D) and spindle nuts (E). The spindle has right and left turn thread for opposite door movements, both opening or both closing. 

This door system can have as well a double leaf as a single leaf configuration.
