The Metaflex CA door runs with an inflatable, double-layer sealing rubber which ensures a complete airtight and gastight seal, even with an uneven floor or wall. After closing, the door can be hermetically sealed and locked with the stainless-steel lever.
To prevent unnecessary opening and closing, the CA door will be provided with a gastight, synthetic revolving window. This allows a visual inspection, without opening the door. The window can be opened from the inside in case of an emergency. As an additional benefit, the revolving window prevents unnecessary energy loss.
