Dynamic Passbox with Explosion-Proof

Explosion-Proof Laminar Flow Passbox Key Features & Functions

1. Core Features

• Explosion-Proof Design:

  • Housing and electrical components comply with anti-explosion standard.

  • Sealed motors, spark-free switches, and HEPA filter.

• Contamination Control:

  • HEPA-filtered unidirectional airflow (0.45±0.1 m/s) maintains ISO Class 5/7 cleanliness during transfers.

  • Optional UV sterilization.

2. Typical Applications

• Chemical/Pharma: Transferring solvents or APIs in explosive atmospheres.

• Oil & Gas: Moving tools/samples between hazardous zones in refineries or labs.

• Battery Manufacturing: Isolating lithium-based materials in dry rooms.

3. Operational Safety

• • Dual-door electronic interlock with pneumatic seals to prevent simultaneous opening.

  • Pressure-resistant construction (stainless steel 306 with welded seams).

1. Explosion Proof Laminar Air Passbox Structure & Material:

• Constructed with high-grade 304 stainless steel, featuring a curved work area for seamless wiping and sterilization compliance.

• Card-slot sealed door panels with durable gaskets (superior to traditional adhesive strips) ensure long-term airtightness.

• Explosion-proof terminal box with protection class IP65.

2. Intelligent Control System

• User-friendly PLC panel with one-touch settings for self-cleaning/UV sterilization cycles (adjustable timing).

• Automated process control includes:

  • (1) Auto door interlock during operation;

  • (2) Self-cleaning countdown with door lock to guarantee preset duration;

  • (3) Post-cleaning reminders: Audible alerts if objects are not removed post-cycle;

  • (4) Door-closure reminder: Alarms after 5 minutes if left open;

  • (5) Smart energy-saving: Fans/lights auto-off per preset schedules.

• Cumulative sterilization logs (viewable/resettable) for compliance tracking.

3. Purification & Safety

• HEPA-filtered laminar airflow prevents cross-contamination.

• UV sterilization lamps eliminate microbes.
