Q1: How does the low-noise design of this air shower pass box
benefit operations in noise-sensitive environments like
pharmaceutical labs or electronics cleanrooms?
This air shower pass box addresses noise concerns with a specially
engineered design, including sound-dampening insulation and
optimized airflow channels that reduce operational noise to ≤60dB.
The quiet operation is critical for environments where noise can
disrupt research, compromise concentration, or violate workplace
safety standards. Despite its low noise, the unit maintains
high-performance particle removal (via HEPA H13 filters with
≥99.99% efficiency at 0.3μm) and rapid air velocity (20–30 m/s),
ensuring cleanroom compliance without sacrificing user comfort.
This balance of quietness and effectiveness makes it ideal for
sensitive applications where both productivity and acoustic control
are essential.
Q2: How does the E-interlock system in this pass box prevent
cross-contamination while ensuring efficient material transfer?
The E-interlock system is a key safety feature that ensures only
one door opens at a time, creating an airtight barrier between
clean and non-clean zones. This prevents cross-contamination, a
critical requirement in GMP-compliant pharmaceutical or food
processing environments. The system integrates with the air
shower’s controls, automatically initiating a 10–15 second purge
cycle to remove particles before the opposing door unlocks. This
seamless process streamlines material transfer while maintaining
ISO 14644-1 Class 5 cleanliness. The intuitive interface and
reliable interlock mechanism reduce operator error, enhancing
safety and efficiency in high-traffic cleanroom workflows.
Q3: How does the 201 stainless steel construction and
960x890x1690mm compact size make this air shower pass box suitable
for space-constrained industrial settings?
The 201 stainless steel build offers corrosion resistance and a
smooth, non-porous surface that resists particle buildup and
simplifies sanitization, making it durable for harsh industrial
environments. The 960x890x1690mm compact design is specifically
engineered to fit into tight spaces while providing an
800x800x800mm interior for bulk material transfer. This
space-efficient layout allows integration into existing cleanroom
layouts without compromising performance. The lightweight yet
robust construction also simplifies installation and maintenance,
reducing downtime. Whether in pharmaceutical labs, electronics
assembly lines, or food production facilities, this unit balances
compactness, durability, and functionality to meet the needs of
modern industrial operations.
