FU-220 Biosafety Negative Pressure Transport Unit
The FU-220 Biosafety Negative Pressure Transport Unit (Patent No. 202010472369.8) is a compact, independently sealed, and fully mobile containment space developed by Cleanair Group. Designed to provide effective biosafety isolation between infectious disease patients, medical personnel, and the surrounding public, the FU-220 is purpose-built for the isolation, observation, and safe transfer of suspected infectious patients — enabling rapid and effective suppression of further viral transmission.
One of the FU-220’s most distinctive advantages is its elevator-compatible design: engineered to fit the standard lift dimensions found at ports, airports, and transit hubs, it can be smoothly transported between floors without the need for ramps or special infrastructure. Combined with dual electric drive wheels and manual push handles, it offers unmatched mobility in confined and high-traffic environments.
Whether stationed at a border checkpoint, deployed in a hospital fever clinic, or held in reserve for emergency response, the FU-220 delivers reliable negative pressure containment with minimal setup time — protecting healthcare workers and the public when it matters most.
The FU-220 is particularly suited for high-density transit and public health settings, including international airports, seaports, high-speed railway stations, and border crossing checkpoints. It is equally appropriate for hospital fever clinics, emergency departments, and other public facilities requiring rapid patient containment.
Its elevator-compatible dimensions make it especially valuable in multi-floor facilities where patient transfer between levels is required. The FU-220 also supports direct negative pressure sampling within the unit, providing a safer operating environment for medical personnel performing specimen collection procedures.
1. Aviation-Inspired Compact Design Sleek and precise in form, the FU-220 features a steel-frame construction with full powder coating. Three-sided transparent protective panels provide clear visibility into the unit from all angles.
2. Dual Mobility System Two electric drive wheels and two universal swivel casters on the base allow effortless manual pushing or remote-controlled electric movement — adaptable to any operational environment.
3. Elevator-Compatible Dimensions Specifically designed to fit standard elevator dimensions at ports and transit facilities, enabling smooth inter-floor patient transfer without modification to existing infrastructure.
4. Reliable Negative Pressure Sealing The robust enclosure structure is fully sealed at all joints, maintaining a stable negative pressure environment that meets regulatory requirements and prevents pathogen escape.
5. Hygienic Interior Construction All interior contact surfaces feature smooth, rounded transitions. A drainage outlet in the base plate allows thorough interior cleaning and waste removal.
6. Mechanical Latch Door System A secure mechanical latch door can be opened and closed with ease, ensuring reliable containment without complex operation.
7. Button-Based Operation All primary functions are operated via simple push-button controls, minimizing the learning curve for frontline personnel.
8. Emergency Alarm System An internal emergency call button triggers an immediate flashing red light and audible alarm, alerting outside personnel to any urgent situation within the unit.
9. 3-Hour Battery Backup Following disconnection from mains power, the UPS battery system maintains full negative pressure operation for a minimum of 3 hours (excluding electric drive movement).
10. Dual Power Compatibility Operates on both mains power and onboard UPS battery, supporting both fixed-location and short-duration mobile deployment.
11. Motion-Controlled UV Disinfection Internal UV disinfection devices are controlled by a human presence sensor, automatically deactivating when personnel enter the unit to ensure occupant safety.
12. Terminal Disinfection System Equipped with a hydrogen peroxide or alternative disinfection system and an internationally standardized quick-connect interface for post-use terminal decontamination.
