PASS BOX

ELECTRICAL INTERLOCK FOR CRITICAL ENVIRONMENTS

A Pass Box is a cleanroom support equipment designed to transfer materials between clean-to-clean rooms or from non-clean areas into cleanrooms while minimizing contamination risks. Constructed from 304 stainless steel with airtight welded structure, and equipped with an electrical interlock system to prevent both doors from opening simultaneously.

• Electrical interlock maintains pressure & prevents cross airflow.
• Hygienic finishing with smooth, easy-to-clean surfaces.
• Optional HEPA filter for added particle protection.
• Durable construction with optional tempered glass doors.
• Wide applications in pharmaceuticals, laboratories, and biotechnology facilities.
