정적 패스 박스

1. Product Overview

The Static Pass Box, also known as Static Transfer Window, is a material transfer device installed between clean and non-clean areas or between zones of different cleanliness levels. Unlike dynamic pass boxes that incorporate fans and filters, the Static Pass Box contains no powered devices and relies solely on physical isolation and interlocking mechanisms to achieve safe material transfer between areas of different cleanliness levels.

The Static Pass Box offers advantages including simple structure, low cost, easy maintenance, and noise-free operation. It is a fundamental material transfer device for cleanrooms and is widely used in pharmaceutical, biological laboratory, electronics manufacturing, and food processing industries.

2. Working Principle

The working principle of the Static Pass Box is based on two core mechanisms: physical isolation and interlock control.

첫째, 물리적 고립.패스 박스 하우징은 서로 다른 청결도 수준의 두 개의 영역을 물리적으로 분리합니다.두 문은 정상적인 조건에서 닫혀 있으며, 양쪽 사이의 직접적인 공기 교환을 방지하는 물리적 장벽을 형성합니다.

Second, Interlock Protection. An interlock device is installed between the two doors. When one door is opened, the opposite door is automatically locked and cannot be opened. This design ensures that only one door can be opened at any given time, effectively preventing cross-contamination through airflow.

Third, Material Transfer Process. The operator on the low-cleanliness side opens the outer door, places the material inside the chamber, and closes the outer door. The interlock then releases the lock on the opposite door. The operator on the high-cleanliness side opens the inner door, removes the material, and closes the inner door, completing one full transfer cycle.

Fourth, Seal Maintenance. When both doors are closed, the sealing device of the pass box ensures airtightness between the housing and doors, maintaining stable pressure differential between the two sides.

3. Product Structure and Components

The Static Pass Box consists of the following core components:

Housing: Manufactured from high-quality stainless steel sheet or cold-rolled steel sheet, with brushed or coated finish. The interior surface is smooth and flat for easy cleaning. The housing structure is robust with good sealing properties.

문: 일반적으로 내용을 관찰하기 위해 투명한 보기 창을 가진 이중층 강화 유리 문 또는 스테인리스 스틸 문.문은 부드러운 열기 및 닫기 위해 문문을 통해 하우징에 연결됩니다.

Interlock Device: Includes mechanical interlock and electronic interlock. Mechanical interlock uses mechanical linkages to achieve door interlocking without power supply. Electronic interlock uses electromagnetic locks and control circuits requiring power supply, offering better reliability and safety.

Sealing Device: High-elasticity sealing gaskets or magnetic sealing strips installed on the door edges to ensure airtightness when doors are closed.

작업 표면: 내부 바닥 표면은 평평한 작업 표면으로 일반적으로 스테인리스로 만들어져 있으며 내마모성 및 청소가 쉽습니다.일부 모델은 무거운 항목을 이동하기 위해 비 전원 롤러를 장착할 수 있습니다.

Handle: Stainless steel handles installed on doors, meeting cleanroom hygiene requirements and providing easy operation.

Indicator Lights: Electronic interlock models typically feature status indicator lights showing door open/close status and interlock status.

버저: 일부 모델은 문이 오랫동안 열려 있을 때 소리적 경보를 방출하여 운영자에게 문을 닫도록 상기시킵니다.

Control Panel: Electronic interlock models are equipped with a simple control panel for controlling interlock logic and alarm settings.

4. 특징 및 이점

First, Simple Structure. The Static Pass Box contains no complex components such as fans or filters. The structure is simple and reliable with low failure rate.

Second, Cost Effective. With no power or filtration systems, the manufacturing and maintenance costs of Static Pass Boxes are significantly lower than dynamic pass boxes, making them suitable for budget-constrained projects.

셋째, 소음 없는 작동.정적 패스 박스는 작동 중에 움직이는 기계적 부품이 없으므로 소음에 민감한 실험실 및 의료 시설에 적합한 완전히 조용한 작동을 가져옵니다.

셋째, 쉬운 유지보수.매일 유지보수는 내부 및 외부 표면을 청소하고 밀봉 가스켓을 검사하는 것으로 제한됩니다.필터 교체 또는 팬 유지 보수가 필요하지 않으므로 유지 보수 작업부하가 낮습니다.

다섯째, 유연한 설치.정적 패스 박스는 경량이고 컴팩트하여 설치를 쉽게 합니다.샌드위치 패널 벽, 벽돌 벽 및 건조벽을 포함한 다양한 벽 유형에 설치할 수 있습니다.

Sixth, Energy Efficient. Static Pass Boxes require no power except for the electronic interlock (which consumes minimal electricity). This meets energy efficiency requirements.

Seventh, Safe and Reliable. The interlock device ensures both doors cannot be opened simultaneously, effectively preventing cross-contamination. Electronic interlock models also feature power-off protection where all doors automatically lock when power is lost.

Eighth, Highly Customizable. Dimensions, materials, interlock type, door style, and other features can be customized according to customer requirements to suit different application scenarios.

Item Characteristics: Determine the internal dimensions based on the size of items to be transferred. Consider the maximum length, width, and height of items, allowing appropriate clearance. For heavy items, consider selecting non-powered rollers.

Frequency of Use: For high-frequency use, electronic interlock type is recommended for fast response and high reliability. For low-frequency use, mechanical interlock type can be selected, requiring no power and offering lower cost.

Installation Environment: Confirm wall type and thickness, and select recessed or wall-mounted installation. For sandwich panel walls, standard recessed installation is suitable. For brick or concrete walls, installation openings must be prepared.

Material Requirements: For pharmaceutical and biological laboratories, all-304 or 316L stainless steel is recommended. For general industrial environments, carbon steel with powder coating is suitable.

Door Type: Choose glass door when real-time viewing of contents is needed. Choose stainless steel door when high durability is required.

10. Installation and Maintenance

Installation Key Points: Cut an opening in the wall according to the external dimensions of the pass box. Insert the pass box housing into the wall opening, ensuring it is level. Fill gaps between the housing and wall with sealing compound or sealing gaskets to ensure sealing. Secure the pass box to the wall using mounting screws or fixing flanges. For electronic interlock type, connect power supply and ground. Install the doors and adjust hinges for smooth opening and closing. Test interlock functionality.

Daily Maintenance: Clean interior and exterior surfaces and viewing windows daily using lint-free cloth and appropriate cleaning agents. Regularly inspect sealing gaskets for aging, damage, or deformation; replace if damaged. Regularly check door hinges for looseness and tighten screws. For mechanical interlock type, regularly check interlock mechanism for smooth operation and apply lubricant if necessary. For electronic interlock type, regularly check indicator lights and buzzer for proper operation; test power-off protection function. Check doors for smooth opening and closing; adjust if sticking occurs.
