The Difference Between Dynamic And Static Pass Boxes

Pass Box is specially designed for the transfer of materials in controlled environments. It is built with high quality stainless steel. It has two doors with inspection window and a mechanical or electronic access management system. The pass box can be integrated easily into walls and can be supplied as an independent unit or as a unit that connects to existing utilities.


The Difference Between Dynamic And Static Pass Boxes


Cleanrooms are specialized zones that are designed in such a manner that it has very low levels of particulate matter. These particulate entities may comprise of dust, airborne organisms, or vaporized particles. The cleanroom pass boxes are used for transporting items or components in and out of the cleanrooms. Apart from providing full protection, the pass boxes also facilitate with the transportation of the products.


Today cleanrooms are used in many phamaceutical operations however operators count for over 82% of all contamination. Whilst cleanrooms are effective, additional pass boxes minimise even further any risk of cross contaminiation.


Working Principle Of Pass Box

Static Pass Box is installed on the wall between the clean room and the other room. It is a rectangular compartment  with two doors – one opens in the clean room and other opens in the other room. The electro-magnetic interlocking system allows opening of any one door at a time. This prevents the direct air flow between the clean room to the other room. This also eliminates the requirement to open the door of the clean room frequently for transferring the material. Pass box helps in achieving the material transfer without compromising the level of cleanliness in the clean room.


The pass boxes are of two types- Static Pass Box and Dynamic Pass Box

Static pass boxes are more widely used when ventilation is not essential.

Dynamic pass boxes offer more flexibility and are mainly used when intially starting a new cleanroom operation.

Static and Dynamic pass boxes, whilst are similar do have fundamental differences.


Static Pass Boxes

The static pass boxes are fitted in the manufacturing areas and they filter the incoming air so that it remains free from adulterants like dust and other contaminants. It provides excellent working performance in the cleanroom unit.

These type of boxes are used to transfer material between 2 clean environments with little or no human intervention.

This box contains an electromagnetic interlock between the 2 doors and from a visual control point of view, an LED light suggests when any door is open.


Dynamic pass boxes

Being as a leading Dynamic pass box manufacturer, our dynamic pass box is designed to transfer the materials in a controlled environment making sure that there is not much movement. It also ensures that there is a controlled ingress of particulate matters into the room and between the sensitive areas.

The Difference Between Dynamic And Static Pass Boxes

This type of box is used to pass material from a non-controlled environment to a controlled environment.

Two interlocking doors on both sizes protect the controlled environment when any transfer takes place.

Depending on the application, dynamic pass box designs can be single door or double door.
