Dynamic Pass Box (DPB): A Robust Solution for Material Transfer in Clean Environments

Within the field of clean environment solutions, BSLtech’s Dynamic Pass Box (DPB)  stands as a critical component for material transfer in high-standard industries such as pharmaceuticals, biological laboratories, and electronics & semiconductors. Designed around the core principles of “self-cleaning, zero leakage, and high adaptability,” this product line is engineered to facilitate safe, sterile material transfer under Class A conditions, effectively mitigating cross-contamination risks.

The DPB  incorporates multiple innovative technologies. Its plate electromagnetic interlock system ensures absolute sealing between doors, preventing contamination from airflow exchange. The workspace features a seamless, arc-shaped design with no dead corners, constructed from 304 stainless steel for superior corrosion resistance, ease of cleaning, and extended durability. A unique dual negative pressure structure, governed by precise airflow control, delivers exceptional sealing performance. Measured outlet air velocity remains consistently at 0.45±20% m/s, significantly exceeding common benchmarks and establishing a reliable “sterile barrier.”

To address diverse application scenarios, the series offers extensive configuration flexibility. Users can select from corner, three-door, or double-layer structures based on layout requirements. Door options include stainless steel frame with tempered glass, embedded tempered glass, or suspended tempered glass. The operational interface supports both Chinese and English languages and allows switching between manual and automatic modes. Furthermore, the product accommodates top or side cable entry and can be equipped with optional modules such as UV germicidal lamps (with power ratings from 62W to 202W) and ozone generators for enhanced sterilization.

“Reliability in material transfer is paramount in industries dependent on pristine environments,” stated the Product Manager at BSLtech. “The Dynamic Pass Box was developed precisely to address the challenges of sealing, cleaning, and scenario adaptation faced by conventional equipment. Through continuous technical refinement and scenario validation, we have established a comprehensive product portfolio that meets wide-ranging needs.” The series currently comprises seven standard models, from BSL-LCTW3-040040 to BSL-LCTW16-100100, with workspace sizes ranging from 400×400×400mm to 1000×1000×1000mm, suitable for transferring items from small reagent bottles to large equipment.

In terms of performance, the DPB series operates below 65dB noise levels with a low power consumption of 0.2-0.3kW, reflecting an energy-efficient design philosophy without compromising cleanliness efficacy. The product line has passed relevant international performance tests and is supplied to the global market. Bestleader Tech also provides customization services, tailoring solutions to specific client requirements regarding cleanliness class, spatial constraints, and functional needs.

As a professional supplier in the cleanroom equipment sector, BSLtech is committed to enhancing product performance through technological innovation. The Dynamic Pass Box DPB series, a key part of its clean transfer portfolio, not only offers customers across industries a dependable choice for material transfer but also contributes to the ongoing elevation of cleanliness standards in critical processes.
