Auto-Door Laminar Flow Pass Box | HEPA-Filtered Touchless Transfer for Critical Zones

Product Description

Robotic-Grade Contamination-Free Transfer
Our Auto-Door Laminar Flow Pass-Through enables zero-human-intervention material movement between controlled environments. The integrated H14 HEPA system delivers ISO Class 5 air purity within the chamber, while motorized doors with infrared sensors eliminate touch-induced contamination.

Featuring adaptive airflow velocity control (adjustable 0.3-0.6m/s), it dynamically compensates for door-opening turbulence. The 316L stainless steel construction with radiused corners meets cGMP sanitization requirements, and the PLC logs all transfer cycles with particle counter interface ports for real-time compliance reporting.

FAQ Highlights

Q: How does laminar flow prevent contamination during door opening?
*A: Our 3-stage protection:

1. Pre-purge cycle: Chamber pre-cleaning before inner door open

2. Air curtain: 0.55m/s downward flow creates particle barrier

3. Step-over design: 80mm raised sill blocks floor contaminants*

Q: What if power fails during operation?
*A: Fail-safe protocols activate:

• Doors auto-lock in closed position

• UPS backup maintains HEPA airflow for 15min

• Mechanical release lever accessible externally*

Q: Can it handle heavy items like media tanks?
*A: Yes, with optional upgrades:

• Load capacity up to 50kg (standard 20kg)

• Conveyor roller track integration

• Floor-embedded installation for trolleys*
