Pass Boxes are critical auxiliary cleanroom devices designed to facilitate the sterile transfer
of materials between classified areas, minimizing personnel movement and preventing
cross-contamination.
STATIC PASS BOX (Passive)
Used to transfer materials between two areas of equal cleanliness levels. Relying on an
airtight design and interlocking doors to maintain environmental integrity without an
integrated filtration system.
Core Features
- ๐ Interlocking: Electro Magnetic Door Interlock with LCD display.
- ๐ก๏ธ Construction: Double-skinned SS 304/316L (1.2mm thick) with coved internal corners.
- โจ Sterilization: Integrated 8W to 11W germicidal UV lamp with digital hour meter.
- ๐๏ธ Visibility: Large tempered glass viewing panels on sandwich-type doors.
Core Functions
- ๐ซ Contamination Barrier: Prevents cross-contamination between zones (Grade D to C/B).
- ๐ Pressure Integrity: Maintains pressure cascade integrity of the cleanroom.
- ๐ถ No Movement: Eliminates the need for operators to move between rooms.
- โก Power: 230 V 1 Phase Electrical Supply.
DYNAMIC PASS BOX (Active)
Designed for sterile transfer between areas with different classifications (e.g.,
uncontrolled to Class 100/ISO 5). Features an active HEPA-filtered air handling system for
self-cleaning.
Technical Specs
- ๐ช๏ธ Airflow: Vertical Laminar Airflow at 0.45 ยฑ 0.05 m/s (approx. 90 FPM).
- ๐งน Filtration: H14 HEPA filters (99.999% @ 0.3ฮผ) and EU-6 grade pre-filters.
- ๐ Monitoring: Magnehelic differential pressure gauge (0-250/500 Pa).
- โ Pressure: Operates under positive pressure relative to the dirtier side.
Applications
- ๐ Pharma: Moving raw materials between non-classified and Grade A/B rooms.
- ๐งช Labs: Microbiology labs requiring zero-particle transfer.
- ๐ Electronics: Semiconductor assembly and sensitive component handling.
- ๐ฅ Healthcare: Safe passage of sterile medical supplies and biotech materials.
