Pass box with lifting doors： Intelligent and safe pass-through equipment in clean environments

I. Core Functions and Advantages

Electric Lifting Transfer: Equipped with a vertically lifting platform, typically ranging from 0.5 to 1.5 meters, adaptable to various height requirements.

Multiple Operation Methods: Includes button control, foot pedal control, and sensor control, meeting convenient operation needs in different scenarios.

Double-Door Interlocking and Sealing Design: Employs a double-door structure; when one door is opened, the other automatically locks to prevent air convection and contaminant diffusion.

Sealing strips around the doors ensure airtightness, meeting the stringent air cleanliness requirements of cleanrooms.

UV Disinfection and Air Purification: Some models have built-in UV germicidal lamps to disinfect the surfaces of transferred items, reducing the risk of secondary contamination.

High-end models are equipped with HEPA filters to further purify the air inside the transfer window, enhancing the cleanliness level.

Anti-Pinch and Safety Protection: Automatically reverses direction when encountering obstacles during lifting to prevent injury to personnel or items.

Some models support electric/manual switching; can be temporarily switched to manual mode in emergencies to ensure safe operation.

II. Structural Composition and Materials

Main Frame: Constructed from high-quality stainless steel (such as SUS304) or cold-rolled steel plate with a baked enamel finish, ensuring durability and ease of cleaning. Compact window design optimizes internal space and improves transfer efficiency.

Lifting Platform: The platform surface is flat and can support items of varying weights, adapting to transfer needs of different sizes and shapes. The lifting mechanism uses high-precision gear and rack or chain drive, ensuring smooth operation and low noise.

bservation Window and Door: The door is equipped with a large tempered glass observation window, offering high transparency for easy observation of the interior. Various door lock designs are available, including concealed locks and electronic locks, ensuring operational safety.

Control System: Microcomputer control supports setting parameters such as lifting speed and dwell time. Some models are equipped with an intercom function for convenient communication between personnel on both sides.

III. Application Scenarios

Hospital Operating Room: Used for transferring surgical instruments and medications, reducing the number of times the operating room door is opened and lowering the risk of infection. Used in conjunction with the airtight operating room door, it forms a complete clean barrier.

Pharmaceutical Plants and Biological Laboratories: Transferring raw materials and samples between areas of different cleanliness levels to prevent cross-contamination. Complies with GMP (Good Manufacturing Practice) requirements, ensuring production safety. Electronics Plants and Cleanrooms: Transferring electronic components and precision instruments to prevent damage to products from dust and static electricity. Improves production efficiency and reduces the frequency of manual operations.

Food Processing Plants: Transferring raw materials and semi-finished products between clean and non-clean areas to ensure food safety.Complies with HACCP (Hazard Analysis and Critical Control Points) system requirements.

IV. Technical Parameters and Optional Functions Basic Parameters: Dimensions: 930(L)×100(W)×1660(H)mm (customizable).

Passage Dimensions: 710(L)×100(W)×750(H)mm (accommodating different item sizes).

Power Supply: 220V, 0.1Kw, low energy consumption.

Material: All stainless steel or cold-rolled steel plate with painted finish, highly corrosion-resistant.

Optional Features

Anti-pinch function: Automatically rebounds when encountering resistance during lifting, ensuring safety.

Intercom function: One-button two-way intercom for convenient communication.

Sensitive lifting: Achieves contactless operation via infrared sensor or foot pedal control.

UV disinfection: Built-in germicidal lamp reduces the risk of secondary contamination of items.

Air shower function: Some models are equipped with an air shower device for further purification of transferred items.
