The working principle of the Aluminum Pass Box can be summarized as High Sealing + Interlocking + Physical Isolation:
Operation Process:
Operator on the low-cleanliness side opens the outer door
Places materials inside the chamber
Closes the outer door (interlock activates)
Operator on the high-cleanliness side opens the inner door
Removes materials and closes the inner door, completing transfer
Interlock Principle:
When one door is opened, the opposite door is automatically locked
Ensures air from both zones does not directly communicate
Prevents pressure differential disruption and contaminant entry
Purification Principle (Optional):
HEPA filter circulates and filters internal air
UV lamp irradiates material surfaces for disinfection
Ensures cleanliness of both materials and environment during transfer
Aluminum Pass Boxes are widely used in the following industries:
1. Pharmaceutical and Drug Manufacturing-
Transfer of raw materials, excipients, semi-finished products between different cleanroom grades
Complies with GMP standards
Supports high-frequency material turnover
2. Biological Laboratories
Transfer of biological reagents, cell cultures, microbial specimens
UV sterilization function ensures experimental safety
Suitable for BSL-2 and above laboratories
3. Electronics and Semiconductor Manufacturing
Clean transfer of chips, circuit boards, precision components
Reduces dust and static interference on components
Improves product yield and production stability
4. Food Processing Industry
Transfer of packaging materials, seasonings, semi-finished products
Prevents pests, dust, and microorganisms from entering production areas
Complies with HACCP food safety standards
5. Medical Facilities
Sterile transfer of medical devices and surgical instruments
Complies with ISO cleanroom standards
Suitable for operating rooms, sterile supply departments
When selecting an Aluminum Pass Box, consider the following factors:
| Factor | Recommendation |
|---|---|
| Material Selection | Stainless steel for high cleanliness requirements; Aluminum for lightweight needs |
| Dimensions | Determine internal space based on maximum material size |
| Interlock Type | Electronic interlock for higher safety; Mechanical interlock for cost-effectiveness |
| Purification Function | UV lamp or HEPA filter required for sterile environments |
| Installation Environment | Verify wall opening dimensions and installation method |
| Certification Requirements | Pharmaceutical industry must comply with GMP standards |
Installation:
Cut corresponding opening in the wall
Use aluminum profile/galvanized sheet/stainless steel for edge trimming
Ensure level installation with proper sealing
Daily Maintenance:
Clean internal and external surfaces daily
Regularly inspect sealing gasket integrity
Test interlock functionality periodically
For HEPA filter units, perform regular integrity testing
The Cleanroom Aluminum Pass Box is an essential material transfer device in controlled environments. Its combination of lightweight aluminum construction, reliable interlock protection, and customizable features makes it an ideal choice for pharmaceutical, laboratory, electronics, and food industry applications. Proper selection, installation, and maintenance ensure long-term reliable operation and contamination control.
Interlock elektronik menyediakan amaran audio / visual apabila pintu dibiarkan terbuka, mencegah kerosakan kemalangan daripada pembukaan paksa, membolehkan integrasi BMS, dan menyokong kawalan akses dengan pencatatan data pengguna.
Gunakan pembinaan keluli tahan karat yang dikimpal sepenuhnya dengan kimpalan jahitan berterusan dan sudut jari lancar. Ini menghapuskan retakan dan celah yang sukar dibersihkan di mana pencemaran boleh berkumpul.
Periksa gasket EPDM atau silikon untuk pemampatan 250% apabila pintu ditutup. Ganti jika keras, retak, atau kehilangan elastisiti. Bersihkan dengan alkohol 70%; mengelakkan klorin atau pembersih asid yang kuat yang menyebabkan kakisan.
Ikuti "bersih terlebih dahulu, kemudian membersihkan jangkitan" - keluarkan pembungkusan luar, basuh dengan alkohol isopropyl 70% atau asid perasetik 0.5%, letakkan dengan jarak antara item, dan terdedah kepada UV selama sekurang-kurangnya 15 minit (30 minit disyorkan).
Ya. USP 797 memerlukan pengambilan sampel permukaan semua kawasan yang dikelaskan termasuk bilik laluan. CSP Kategori 1/2 memerlukan sampel bulanan; Kategori 3 memerlukan pengambilan sampel mingguan dan pengambilan sampel hujung kumpulan.
Tugaskan klasifikasi ISO ruang yang lebih bersih. Sebagai contoh, jika laluan menyambungkan ISO 8 kepada ISO 7, mengklasifikasikannya sebagai ISO 7. Amalan terbaik industri mengikuti standard yang lebih tinggi dari dua kawasan yang berkaitan.
Interlock (mekanikal atau elektronik) hanya membolehkan satu pintu dibuka pada satu masa. Apabila satu pintu dibuka, pintu sebaliknya dikunci secara automatik, mewujudkan kunci udara yang mencegah pencemaran silang dan mengekalkan perbezaan tekanan bilik.
Bilik melalui adalah kandang yang dipasang di dinding bilik bersih untuk memudahkan pemindahan bahan antara kawasan sambil meminimumkan risiko pencemaran. Ia mengurangkan lalu lintas kaki, mengekalkan tekanan perbezaan, dan menghalang pertukaran udara yang tidak ditapis melalui pintu yang saling terkunci.
