Dortek hermetic sealing sliding doors are designed for areas where control of air leakage is critical.
The door has a patented track system so it seals perfectly against the floor and frame.
Air leakage has been tested independently and results up to 400 Pa pressure differential are available upon request.
The efficiency of the seal has been officially tested and results show it to be over 99% effective thus reducing cross-contamination, dirty air entering the cleanroom and expensive air handling costs.
