DPB/DFLH: Dynamic Pass Boxes And Dynamic Floor Laminar Hatches

Maintaining environmental integrity during the transfer of materials between different cleanliness zones is a critical challenge in pharmaceutical and high-tech manufacturing. Dynamic pass boxes and floor laminar hatches address this by providing an active aseptic barrier, utilizing vertical laminar airflow to flush the transfer zone with HEPA-filtered air. This process effectively removes trace contaminants and maintains pressure differentials, acting as a robust material airlock that aligns with revised EU GMP Annex 1 requirements.

Unlike static systems, these dynamic units utilize recirculating airflow and on-board fans to ensure a constant supply of clean air without requiring complex external ducting. This prevents cross-contamination during the delivery of goods between areas of contrasting cleanliness grades, making it an essential component for cGMP-compliant facilities. By integrating these systems into your facility, you can ensure that material movement does not compromise your critical process environments.
