Sliding door is used to transfer material between chambers, from a chamber to the environment or from a chamber to another piece of equipment (e.g. fume hood). Movement of the sliding door is controlled by a foot switch or touch control panel. In the vertical direction the door is moved by a pneumatic cylinder. When the sliding door is used, compressed air must be brought to the isolator. Two seal versions are available: static or pneumatic. The door is made of AISI 316L, POM-C compliant with FDA CRF.177.2470; the silicone seal is FDA CRF.177.2600 compliant.
