Containment cabinet HLF

laboratorymedicalfor the pharmaceutical industry

Overview
Envair Technology’s HLF horizontal laminar airflow cabinets deliver unidirectional airflow directed toward the operator to provide better than ISO 5 / EC GMP Grade A air quality at the work zone. Cabinets feature a mobile frame and variable‑speed super‑silent fans that establish sterile conditions quickly with minimal impact on room pressures. Units are designed for straightforward installation, movement and operation in medical and clean‑room environments.

Applications

• Hospital pharmacy compounding (e.g., TPN, IV bag preparation)
• Sterile tissue culture and laboratory aseptic work
• Handling sterile pharmaceutical powders or liquids that do not pose operator hazard
• Assembly of micro‑electronics and precision components
• Precision mechanical assembly of inertial platforms, hard disk drives, etc.

Key features

• DOP test port for performance verification
• Clear side screens for visibility
• Siemens colour touchscreen HMI for control and monitoring
• Available in powder‑coated mild steel or stainless steel finishes
• 316L stainless steel work surface
• Integrated LED lighting
• Optional table frame with lockable castors or levelling feet
• Optional variable‑height stand
• Provision for service taps (vacuum, compressed air)
• Electrical sockets

Performance and operation
Unidirectional horizontal airflow supplies ‘first air’ protection across the work zone. Variable‑speed, super‑silent fans enable rapid establishment of sterile air conditions while minimizing disturbance to room pressure balances. Controls are accessible via Siemens HMI for straightforward start‑up, speed adjustment and monitoring.

Construction and finishes
Choice of powder‑coated mild steel or stainless steel cabinet finishes. Work surface manufactured in 316L stainless steel for corrosion resistance and cleanability. Clear side screens and LED illumination support visual tasks; mobile frame allows relocation without significant installation works.
