Airtight Door
product description
products center
Mingren airtight doors are purpose-built for sealed clean environments, directly manufactured by our factory. Centered on three core advantages: superior airtightness, antibacterial durability and operational safety, our products meet the strict requirements of various clean scenarios. We provide both standard in-stock sizes and non-standard customized solutions, with fast delivery and comprehensive after-sales support
## 1. Antibacterial & Durable for Long Service Life
Our doors are constructed from galvanized steel or 304 stainless steel with seamless integral molding, eliminating dirt-trapping gaps. The antibacterial coating withstands long-term disinfection spraying and wiping (including 84 disinfectant and alcohol) without rusting or paint peeling. Honeycomb filling enhances impact resistance, allowing the door to resist dents from frequent bumps by hospital beds and material trolleys, delivering outstanding durability under heavy daily usage in hospitals and factories. Double-layer sealed anti-fog glass windows maintain clear visibility throughout the extended service life
## 2. Multi-layer Sealing to Preserve Indoor Cleanliness
By combining stepped door frames, full-circle sealing strips and automatically lowering bottom sealing strips, the door forms a fully enclosed space after closing. It stably maintains indoor positive or negative pressure, blocks external dust, bacteria and odors, and prevents internal clean air leakage. This fundamentally eliminates cleanliness non-compliance caused by air leakage in operating rooms and production workshops. The acid and alkali resistant sealing rubber has excellent anti-aging properties, requiring no frequent replacement
## 3. Flexible Customization & One-Stop Service
We provide customizable single-leaf and double-leaf doors, with optional accessories including crash strips, access control systems and interlocking linkage systems. Custom door colors are also available. Our factory delivers one-stop services including on-site measurement, installation and commissioning, resolving common air leakage problems at installation gaps. All products are covered by an extended warranty, with convenient spare parts supply. Bulk orders enjoy the price advantage of direct factory sales
## 4. Application Scenarios
Hospital operating rooms, isolation wards, medical aesthetic operating rooms, pharmaceutical sterile workshops, food clean production lines, electronic dust-free workshops, research negative-pressure laboratories, and all other spaces that require sealed bacteria and dust control
