What Is a Laminar Flow Cart?
It is a mobile cleanroom device equipped with a high-efficiency HEPA/ULPA filtration system, fan, sealed chamber, pressure monitoring system, and disinfection interface. During transport, it consistently provides clean, unidirectional airflow, forming an independent sterile space for the items being moved.
Its main functions include preventing the entry of microorganisms and external dust, avoiding cross-contamination, and maintaining the cleanliness of transported items.
Therefore, it is not only a transport tool but also a mobile cleanroom system.
Why Can It Create a "Seamless Sterile Bridge"?
ISO Class 5 Continuous Purification Protection
The high-efficiency filter can capture particles ≥0.3 microns, with a filtration efficiency exceeding 99.99%. Regardless of environmental cleanliness during transport, internal cleanliness remains consistent.
Positive-Pressure Airflow Barrier
A stable positive-pressure environment prevents external air backflow and contaminant intrusion.
Fully Sealed Structural Design
A sealed compartment with seamless welding prevents bacteria and dust from entering through gaps.
Strict Control of Internal and External Transfer Modules
Some models are equipped with interlock doors and ultraviolet disinfection devices to ensure strict access control.
This design enables complete aseptic isolation from "Clean Zone A" to a "General Zone," and then to the "Target Clean Zone."Laminar flow carts ensure truly contamination-free movement across different areas.
