Product Overview  ——Cleanliness Standard Dispensing Booth for Negative Pressure Containment in Hospital

LAF/Weighing Booth/Dispensing Booth

Cleanroom LAF is a local purification device that generates stable, eddy-free unidirectional airflow to quickly remove contaminants and prevent their deposition on products. It is widely used in scenarios with high cleanliness requirements such as and microelectronics.

Features at a Glance

• Precise Guarantee of Local High Cleanliness, Reducing Contamination Risks in Core Processes

   

  The unidirectional laminar airflow generated by LAF systems is eddy-free and dead-corner-free. Combined with HEPA/ULPA filtration (with a filtration efficiency of ≥ 99.97% for particles ≥ 0.3μm), it can maintain a stable ISO Class 5 or higher clean environment at the operation workstation, quickly removing airborne particulates and microorganisms to prevent their deposition and product contamination. Compared with the full-room high-grade cleanliness design, LAF focuses on critical processes (such as sterile drug filling and microelectronic chip packaging), reducing the incidence of contamination incidents by more than 40%. It is particularly suitable for precision manufacturing and biopharmaceutical fields sensitive to impurities.
   
• Significantly Reduce Construction and Operational Costs, Improving Economic Efficiency

   

  There is no need to upgrade the entire cleanroom to high-grade standards. Only local purification of core workstations through LAF units can reduce the area of high-energy-consuming clean space by more than 60%. On the one hand, it cuts down the initial investment in decoration and air conditioning systems; on the other hand, the modular design of LAF allows flexible mobile deployment to adapt to production line adjustment needs, while reducing energy consumption for full-room constant temperature and humidity control. The long-term operational cost is 30%–50% lower than that of the full-room high-grade cleanliness solution.
   
• Meet Stringent Industry Standards, Simplify Compliance Verification Processes

   

  LAF features stable airflow velocity (0.3–0.5 m/s) and predictable flow direction, fully complying with the requirements of strict standards such as GMP, ISO 14644-1, and USP <797>. Through smoke tracer tests, particle counter detection, and other methods, the airflow organization and cleanliness compliance can be intuitively verified, and traceable data reports can be generated, reducing the risk of audit rectification. It is especially suitable for pharmaceutical and medical device enterprises that need to pass compliance certification.
   
• Flexible and User-Friendly Operation, Adapting to Diverse Process Requirements
   
  • Airflow type selection on demand: Horizontal laminar flow is suitable for scenarios such as sample weighing and small-part product assembly, where airflow moves parallel to the workbench surface to remove contaminants; vertical laminar flow can form an "air barrier" to protect both operators and products (e.g., when used in conjunction with biological safety cabinets).
  • Modular LAF units support quick installation and movement, enabling flexible adjustment of workstation layouts according to production line changes to meet the needs of multi-variety and small-batch production. The enclosed structure also reduces noise and ensures uniform temperature control, improving operator comfort and reducing fatigue-induced errors during long-hour operations.
   
• Convenient and Controllable Maintenance, Ensuring Long-Term Stable Operation

   

  The modular design of LAF systems standardizes maintenance operations such as filter replacement and air velocity calibration, eliminating the need for full-room shutdown for maintenance. Equipped with online monitoring modules, it can conduct real-time monitoring of airflow velocity and particle concentration, set up abnormal alarms, and avoid potential fault risks in advance. Meanwhile, continuous laminar air cleaning reduces reliance on high-frequency workstation disinfection, extends the service life of equipment and consumables, and further lowers operation and maintenance costs.

Products Description

• Housing/Casing: Constructed from stainless steel, aluminum, or coated galvanized steel for durability, cleanability, and corrosion resistance.

• HEPA/ULPA Filter: The core filtration element, mounted on the discharge side, providing final air cleaning.

• Centrifugal Blower Fan: Typically a backward-curved impeller design, providing stable airflow with good energy efficiency and low noise. Units may feature single or multiple fans (for redundancy).

• Pre-filter: Usually a primary (G4) or medium-efficiency (F8) filter located at the fan inlet. It protects the main HEPA filter and extends its service life by capturing larger particles.

• Control System:

  • Speed Control: Modern FFUs predominantly use Electronically Commutated (EC) motors, allowing infinite variable speed control via 0-10V DC, PWM signals, or network commands. This enables precise airflow adjustment and significant energy savings compared to older AC motor designs.

  • Monitoring: May include integrated differential pressure sensors (to monitor filter loading), status indicator lights, alarm functions, and communication interfaces for connection to Building Management Systems (BMS).

• Airflow Diffuser/Perforated Plate: Mounted below the filter, it helps to equalize and stabilize the discharged airflow, promoting uniform laminar flow.
