Airtight Automatic Sliding Door for Operating Rooms & Cleanrooms

The airtight automatic sliding door for operating rooms, ICUs and cleanrooms: a sealed leaf, an overhead operator kept outside the clean zone, and EN 12207 Class 4 airtightness as standard.

EN 12207 Class 4 Sealing

The airtight automatic sliding door closes against a machined frame with a continuous silicone gasket channel, achieving EN 12207 Class 4 - the highest airtightness grade. When the leaf reaches the closed position, it drops against the floor seal and compresses the perimeter gasket simultaneously. This dual sealing maintains the room pressure differential (typically 15-25Pa for operating theatres, 10-20Pa for cleanroom cascades) without leakage.

Sealed Overhead Track, Brushless Operator

The operator runs on a sealed overhead track completely outside the clean zone - no lubrication, no particles, no maintenance entry required. Brushless DC motors provide smooth, quiet travel with adjustable speed and dwell time. Safety sensors reverse the leaf on obstruction; a battery backup opens the door on power failure.

Activation and Interlock Options

Activation options include radar motion sensor (default), infrared presence sensor, foot switch for scrubbed staff, or card reader for access-controlled areas. Optional interlock controller manages two-door airlock sequences with configurable delay and pressure-equalization timing.

Faces Matched to the Cleaning Protocol

Door surfaces are specified for the cleaning protocol of the facility: HPL laminate with antibacterial finish for standard clinical areas, or 304 stainless steel for CSSD, pharmaceutical cleanrooms and areas with hydrogen peroxide vapor decontamination. All surfaces are non-shedding and withstand alcohol, chlorine and quaternary ammonium disinfectants.
