VHP (Vaporized Hydrogen Peroxide) H2O2 Pass Box

A cleanroom VHP pass box is a specialized piece of cleanroom equipment that is used to transfer materials between a cleanroom and the surrounding environment while maintaining the cleanliness and purity of the cleanroom. The VHP pass box uses vaporized hydrogen peroxide (VHP) as a disinfectant to kill any bacteria, microbes, or other contaminants that may be present on the materials being transferred. This helps to prevent the introduction of contamination into the cleanroom and maintain a high level of cleanliness and purity.

Cleanroom VHP pass boxes are commonly used in industries such as pharmaceuticals, medical device manufacturing, and semiconductor manufacturing, where maintaining a clean and sterile environment is critical. They are typically used to transfer materials such as samples, documents, or tools into and out of the cleanroom without introducing contamination from the surrounding environment.

The types of pass boxes are Static Pass Boxes, Dynamic Pass Boxes, Transfer Hatch, and VHP pass boxes. The VHP Pass box integrates a VHP (Vaporized Hydrogen Peroxide) generator in box.

VHP pass boxes are typically small, enclosed areas that are located between the cleanroom and other areas, such as a storage room or an equipment room. They are equipped with a set of double doors, with interlocks that prevent both doors from being opened at the same time. This ensures that the cleanroom is not exposed to the outside environment when materials are being transferred.

The pass box is typically made of stainless steel or other materials that are easy to clean and resistant to contamination. It is equipped with a VHP generator and a UV lamp to kill any bacteria or other contaminants on the materials being transferred. In some cases, the pass box may also be equipped with an ozone generator sterilization system to provide an additional level of cleanliness and sterilization.

In addition to these features, VHP pass boxes are designed with a circular arc internal area to avoid hygienic dead corners and make them easy to clean. The built-in air return plate and internal cavity are laser-drilled and cold-pressed to create a seamless and smooth surface that is less prone to contamination. The control panel is made of S304 stainless steel for durability and ease of cleaning. The door panel is designed with a double-layer negative pressure system to prevent leakage, and the working area is designed for positive

The VHP pass box can be used for various small items with Class A and Class B criticality required in aseptic production. It can effectively avoid biological pollution caused by transferring items between clean areas and unclean areas. And because of the small scope of action, it avoids the flow of people caused by the need to transfer items and reduces the risk of pollution.
VHP pass box is widely used in microtechnology, biological laboratories, pharmaceutical factories, hospitals, food processing plants and other places.
Items suitable for delivery include: outer packaging of items, clean room supplies, raw materials, auxiliary reaction supplies, experimental accessories, environmental monitoring equipment, etc.

The VHP pass box is a specialized piece of cleanroom equipment used to transfer materials between low-level clean areas and high-level clean areas while maintaining the cleanliness of the environment. The pass box features a built-in vaporized hydrogen peroxide (VHP) generator, which is used to deliver VHP gas to the interior of the pass box for biological decontamination treatment on the exterior surface of the materials being transferred.

This allows the VHP pass box to be used for a wide variety of clean and dry materials, such as packing supplies, tools, raw materials, auxiliary supplies, accessories, and environmental monitoring equipment, which need to be provided in aseptic production and enter A or B critical regions. The VHP pass box operates at biologically appropriate low temperatures (18-26 °C) and uses clean compressed air as its power source, reducing the amount of indoor inlet manifold and swiftly dehumidifying to lower the overall sterilizing time and decrease the likelihood of condensation in the cabin.

The VHP pass box features a processing time of ≤50 minutes for a 3 m³ chamber, and has a rounded inner chamber and tank for easy cleaning. The tempering glass doors provide a clear view of the internal area, while the pneumatically linked doors ensure that only one door can be opened at a time. The main body is constructed of stainless steel 304 or Aisi316L, which is also used for the transfer hatch. The pass box is equipped with Siemens PLC control and offers 6 operating modes for manual or automatic operation.

Additionally, the VHP pass box features a HEPA filter of grade H14, ensuring that no hazardous residues or odors are produced. The pass box is designed to follow GMP and USP guidelines and to preserve every detail, making it a reliable and effective solution for maintaining a clean and sterile environment.

what is cleanroom VHP pass box used for?

A cleanroom VHP pass box is a type of enclosure that is used to transfer materials between a cleanroom or other controlled environment and an adjacent area that is not necessarily controlled. It is typically used in laboratories and other environments where the contamination of materials must be minimized.

Cleanroom VHP pass boxes are equipped with a vaporized hydrogen peroxide (VHP) system that is used to decontaminate the inside of the pass box between transfers. This helps to ensure that the risk of contamination is minimized, even when transferring materials between controlled and non-controlled environments.

Cleanroom VHP pass boxes are used in a variety of settings where the accurate and reliable transfer of materials between a controlled environment and an adjacent area is critical, and where the risk of contamination must be minimized. These settings may include:

Pharmaceutical and biotech industries: Cleanroom VHP pass boxes are commonly used in the production of pharmaceuticals and other biotech products, where the purity and integrity of the materials being transferred is of the utmost importance.

Medical and research laboratories: Cleanroom VHP pass boxes are also used in medical and research laboratories, where the accurate transfer of materials between a controlled environment and an adjacent area is necessary for the conduct of experiments and the development of new products.

Food and beverage industry: Cleanroom VHP pass boxes are used in the food and beverage industry to transfer materials between a controlled environment and an adjacent area, as well as to ensure the quality and safety of these materials.

Aerospace and defense industry: Cleanroom VHP pass boxes are used in the aerospace and defense industry to transfer materials between a controlled environment and an adjacent area used in the production of aircraft and other advanced technology.

Overall, cleanroom VHP pass boxes are an essential tool for any facility where the accurate and reliable transfer of materials between a controlled environment and an adjacent area is critical, and where the risk of contamination must be minimized.
