Hospital Hermetic Cleanroom Door Engineering Overview
Airtight pressure barrier, touchless hygiene access & AERB radiation containment
As a leading Hermetic Door Supplier in India, Bio Meditech designs, manufactures, and installs high-performance automatic sliding hermetic doors for modular operation theatres, intensive care isolation suites, and medical imaging departments.
Our doors utilize an engineered 4-way drop-and-slide track system. During the final travel stroke, the door blade drops 15mm downward onto the floor and shifts 10mm inward toward the wall frame, compressing continuous multi-chamber EPDM rubber gaskets on all four sides. This hermetic seal preserves sterile cleanroom air pressure differentials (+15 to +20 Pascals) and stops airborne infection cross-contamination.
Available in SS 304 Stainless Steel or anti-bacterial High-Pressure Compact Laminate (HPL), our doors can be custom-ordered with 2mm to 3mm continuous lead shielding and lead-glass vision panels certified for AERB radiation containment in Cath Labs, CT scanner rooms, and hybrid surgical suites.

Frequently Asked Questions (FAQs)
What is the price of an automatic hermetic sliding OT door in India?
In India, hospital hermetic door pricing ranges from ₹85,000 to ₹1,45,000 for manual hermetic cleanroom sliding doors, ₹1,85,000 to ₹2,90,000 for automatic sliding hermetic doors with HPL finish and touchless sensors, ₹2,60,000 to ₹3,80,000 for premium SS 304 stainless steel automatic hermetic doors, and ₹3,40,000 to ₹5,50,000+ for lead-shielded radiation protection doors (2mm-3mm Pb with lead glass) for Cath Labs and X-Ray rooms. Bio Meditech provides direct manufacturer pricing and customized GeM tender BOQ quotations.
How does the 4-way hermetic sealing mechanism work?
Unlike ordinary sliding doors that simply roll horizontally, a hermetic door track incorporates a specialized cam incline at the closing position. When the door reaches the closed point, it drops 15mm downward onto the floor and shifts 10mm inward toward the door frame. This mechanical movement firmly compresses continuous silicone/EPDM gaskets against the wall and floor, creating an airtight seal that prevents pressure loss.
What lead thickness is required for Cath Lab and X-Ray room radiation doors?
Under Atomic Energy Regulatory Board (AERB) guidelines in India, diagnostic X-Ray and CT rooms typically require 2.0mm lead equivalence (Pb), while Cath Labs, interventional radiology suites, and radiotherapy rooms frequently require 2.5mm to 3.0mm lead equivalence. Bio Meditech provides custom-calculated lead sheet cores with certified lead glass vision panels.
What is the difference between an HPL door blade and an SS 304 door blade?
An HPL (High-Pressure Laminate) door blade features an anti-bacterial resin-impregnated compact sheet available in various hospital colors, offering high impact resistance and scratch protection. An SS 304 door blade is clad in 1.0mm medical-grade stainless steel with a satin hairline finish, providing ultimate chemical resistance against aggressive sterilizing agents.
What happens to the automatic door during a power failure?
Our automatic hermetic doors include an integrated emergency rechargeable battery backup that provides over 200 open/close cycles during power outages. Additionally, the manual operating force is engineered to be less than 3.5kg, allowing clinical staff to push the door open effortlessly by hand in emergencies.
Does Bio Meditech provide on-site installation and AERB/NABH documentation in UP & India?
Yes. Headquartered in Lucknow, Bio Meditech biomedical engineers handle complete turnkey structural track installation, motor commissioning, airtightness smoke testing, and AERB radiation survey validation across Lucknow, Kanpur, Varanasi, Gorakhpur, Prayagraj, Noida, Patna, and all surrounding areas.
