DQ of Dynamic Pass Box (Design Qualification)

OBJECTIVE for DQ of Dynamic Pass Box

To determine that the DQ of Dynamic Pass Box perform as intended by repeatedly running the system on its intended schedules and recording all relevant information and data. Results must demonstrate that Design consistently meets per-determined specifications under normal condition, and where appropriate the worst case situations.

RESPONSIBILITY:

Customer:

To provide the Scope of supply.

To give final approval to drawing and technical data sheet.

Manufacturer:

To design, engineer and provide complete technical details of the Equipment.

To confirm safe delivery of the equipment to the user site.

To ensure that no un-authorized and/or unrecorded design modifications shall take place. If at any point of time, any change is desired by mutually agreed design, change control procedure shall be followed and documented.

SCOPE OF SUPPLY:

  • Design of the machine shall meet the Scope of Supply finalized with the Customer.
  • To define the customer’s & the manufacturer’s responsibilities.
  • To provide the brief process description of Dynamic Pass Box.
  • To provide the technical Specifications of the Dynamic Pass Box.
  • To provide the information on bought out components.

BRIEF PROCESS DESCRIPTION for DQ of Dynamic Pass Box:

  • Dynamic pass box is normally used to transfer materials and goods between clean rooms of different levels or between clean room and non-clean room. Besides UV light and an interlock system, dynamic pass box is equipped with a suction HEPA filter.  A dynamic pass box works like an airlock or laminar it has an interlocking system on both sides to protect from contamination and cross-contamination. Dynamic pass box door can open one side at once, and the other side door remains closed.
  • Dynamic pass box is a self cleaning pass box. The air sucked by a centrifugal blower than passed through HEPA filter. After the pressure is equalized, the filtered air enters the working zone at a uniform air velocity, forming a clean working environment
  • When the material is put inside pass box & the door is closed, UV light will turn on and material is placed under UV for some time to kill bacteria. Then the material can be taken out.
  • The basic construction of the machine consists of :
  • Standard stainless steel 316 L for contact parts
  • Non contact parts SS304 with matt finish
  • Non metallic contact parts,    any material with food grade quality having no       potential impact on the products

Body:

     The body of the box consists of the outer casing and the inner chamber.

Doors:

Two doors (one on each side) with tempered glass windows sealed by durable feather edge rubber prevent airborne particles contamination. Besides, each door has door handle. The door handles are different according to the types of interlock system.

Interlock system:

This is an important of every pass box, ensuring two doors don’t open at the same time. This prevent the risk of cross contamination in clean rooms

UV Light

UV light are designed inside pass box for disinfection of transferred objects before entering the clean room

Fan

It sucks the air and blows it through HEPA filter. The clean air will go into the chamber to sterilize the objects 

Filters

Filters are used to remove the airborne particles

Differential pressure gauge

To check the differential pressure across hepa filters

Blower and fan

Clean air enters the inner space of pass box, dilutes and filters the air inside.

Electrical chamber and mechanical chamber: 

All mechanical components such as gears, motors, and moving belts, as well as electrical components such as wiring, switches, and MCBs, are installed in this segment.
