What materials is Static Pass Box Made of?

A static pass is manufactured with the following materials

• Stainless steel in cubical shape
• Electromagnetic LED indicator
• 8watts UV light
• UV light meter
• 40watts capacity
• No filter

What are the Differences between a Static Pass Box and a Dynamic Pass Box?

Static Pass Box

• This type of pass box is an auxiliary between rooms of the same air quality. It is widely used in rooms with limited personnel movements.
• Static pass box is only applied for cleanroom to cleanroom activities.
• Static pass box doors have an electromagnetic interlock fitted with a LED light that allows the user to know when a door is open.
• Since the channeling of items only happens between rooms of the same air standard, the static pass box does not have an interlock guard system.
• Static pass box does not have filters
• It is designed to prevent air particulate from ambient surroundings to enter the cleanroom.

Dynamic pass box

• It is best used in transferring materials between uncontrolled compartments to controlled compartments.
• This type of box has interlocked doors that prevent cross-contamination in the event of channeling the materials.
• A dynamic pass box has an interlock guard system that allows control of the inlet and the outlet. Hence, not both can be opened at the same time. This method helps in decontaminating the materials being transported from both rooms.
• It has a filter of 0.3 microns stainless steel and 10 microns aluminum.
• This type of pass box has a 0-25mmwc pressure gauge, and a motor blower for about 1/5 that helps in shaving off dust particles.

What Industries Use Static Pass Box?

A static pass box is applied in the various industrial institutions. In many cases is used in:

• Pharmaceutical
• Microbiology laboratories
• Microelectronic laboratories
• Scientific Researches laboratories
• Precision Instrument Manufacturer

Why is there a Need for a Static Pass Box?

• Cross-contamination is the most dreaded part of manufacturing products in industries like pharmaceuticals, research laboratories, and microelectronic laboratories.
• Static pass box then plays a vital role in containing the clean air in the cleanroom. As it only allows transport of material from rooms of the same air quality, it keeps the balance inside the facilities.
• Through this, dust particles and contaminants are put at bay keeping the products safe and secure.
