패스박스 Pass Box

제품 개요

패스박스는 청정실 출입구나 청정 등급이 다른 방 사이에 설치하여, 양쪽 기류가 직접 통하지 않게 하면서 물자를 전달합니다. 두 짝의 문이 인터록되어 동시에 열리지 않으므로 물건을 넣고 문을 닫은 뒤 반대쪽에서 열어 꺼내며, 실내외 공기가 직접 통하는 일이 없습니다. 비송풍형은 에어록으로 기류를 차단하므로 청정 등급이 비슷한 방 사이의 전달에 적합합니다. 송풍형은 케이싱 상부에 고성능 필터와 노즐을 달아 물건이 들어오면 청정 기류로 표면 먼지를 먼저 털어낸 뒤 전달하며, 외부 물자가 고청정 구역으로 들어오는 경우에 씁니다. 양쪽 문 안쪽 가장자리에 전용 실링 스트립을 달아 기밀을 확보합니다.

상세 설명

The interlock is the whole point

A pass box looks like nothing more than a box with two doors, and the only thing it actually does is guarantee those two doors never open together. Without the interlock the box becomes a short duct connecting outside air straight into the cleanroom. Mechanical interlocks use linkages: simple, unaffected by power loss, but heavier to operate. Electrical interlocks use solenoid locks and sensors, feel lighter, and allow indicator lamps and buzzers — but the fail state on power loss, locked or released, has to be confirmed. For high classifications or transfers across a pressure differential, an electrical interlock with status indication is the better choice.

When the blow type is needed

The deciding question is where the material comes from. For transfers between adjacent rooms inside the clean zone, the plain type is enough — both sides are of similar cleanliness and the airlock does the job. When material enters a high-grade zone from a general area, its packaging carries outside particles, and an airlock cannot remove what is stuck to the object. That is where the blow type belongs, sweeping the surface with clean air first. External material entries in semiconductor and pharmaceutical plants are almost always the blow type.

Do not size on the item alone

The internal code is the clear internal dimension: 555 means a 500mm internal square, 888 an 800mm one. Leave working clearance when selecting — if an item only just fits, operators have to reach inside and manoeuvre it, and contact with the inner wall sheds particles. Installation height is the other commonly missed factor. A pass box is built into a wall, and the shelf height dictates the posture used to load and unload. Too low forces bending, too high makes heavy items hazardous, and any floor level difference between the two rooms has to be taken into account at design stage.
