Q1: How does this GMP/ISO-Certified Air Shower Pass Box ensure
compliance with pharmaceutical and electronics industry standards
while preventing cross-contamination?
This pass box is rigorously certified to meet GMP Annex 1 and ISO
14644-1 Class 5 cleanliness requirements, ensuring sterile material
transfer in regulated environments. It features HEPA H14 filters
(≥99.995% efficiency at 0.3μm) and a laminar airflow system that
maintains particle-free conditions. The 304 stainless steel
construction provides a smooth, non-porous surface that resists
particle buildup and simplifies sanitization, critical for GMP
compliance. The electronic interlock system ensures only one door
opens at a time, creating an airtight barrier to prevent
cross-contamination. Optional UV-C sterilization further eliminates
microbial risks, making it ideal for pharmaceutical manufacturing,
electronics assembly, or any application requiring strict
contamination control.
Q2: Can the 304 stainless steel construction and electronic
interlock system withstand frequent use and harsh chemicals in
pharmaceutical or electronics cleanrooms?
Yes. The 304 stainless steel build offers superior corrosion
resistance, making it suitable for environments with daily
sanitization or exposure to mild chemicals. Its durable, non-porous
surface resists scratches and particle adhesion, reducing
maintenance and contamination risks. The electronic interlock
system is engineered for reliability, with fail-safe mechanisms
that prevent door malfunctions even in high-traffic settings. The
pass box is designed for heavy use, with welded seams and airtight
seals that maintain structural integrity over time. Routine
maintenance, such as filter replacements (HEPA filters every 12–18
months) and gasket inspections, ensures long-term performance in
demanding cleanroom environments.
Q3: How does the electronic interlock system in this Air Shower
Pass Box improve operational efficiency and safety in
pharmaceutical or electronics workflows?
The electronic interlock system streamlines material transfer by
automatically coordinating door movements, eliminating the risk of
simultaneous door openings and cross-contamination. It integrates
with the air shower’s controls to initiate a timed purge cycle
(10–15 seconds) that removes particles before the opposing door
unlocks, ensuring efficient, compliant transfers. The intuitive
interface reduces operator error, while real-time status indicators
(e.g., door position, filter alerts) enhance visibility. This
system not only improves safety but also minimizes downtime in
high-throughput operations, making it an essential tool for
pharmaceutical production lines or electronics assembly where speed
and precision are critical.
