Functional description

Low-leakage steel doors are low-leakage separating elements for rooms or other enclosures.

When the door is being closed, i.e. when the double locking levers are being turned, the perimeter seal is fully pressed against the frame. As a consequence, the air leakage rate is extremely low even in case of high differential pressures.
