Chuqi stands as a premier provider of high-precision diffusion media for the global life sciences and microelectronics industries. We understand that in biological pharmacy, air diffusion stability is as critical as filtration efficiency. Our LW-650G series is engineered with a focus on deep-bed filtration, utilizing a progressive density structure that significantly outlasts standard media. By mastering the balance of 3D glue dipping and heat-welded fiber technology, Chuqi ensures that our clients in the semiconductor and medical sectors achieve the most stable, particulate-free micro-environments possible.

Q1: Is the LW-650G filter suitable for Class 100 environments?
Yes. It is specifically designed to meet the rigorous demands of 100,000–1,000 magnitude environments, making it ideal for the most sensitive cleanroom grades.
Q2: How does the “progressive density” design benefit my lab’s HVAC system?
This design allows for deep-bed filtration, meaning dust is captured throughout the full 22mm – 24mm thickness of the media rather than just on the surface. This extends the filter’s life and reduces pressure drop.
Q3: Can fibers shed from the filter and contaminate my samples?
Absolutely not. Our media uses heat-welded fibers that eliminate the risk of shedding, ensuring total air purity for vaccine production and research.
Q4: What makes this media ideal for “biological pharmacy” applications?
Beyond its F5 efficiency, the balanced air velocity it provides creates a stable laminar flow across the air outgoing surface, which is critical for maintaining sterile boundaries in pharmacy labs.
Q5: How does the 3D glue dipping technology improve filtration?
It ensures that every fiber in the matrix is active in capturing particles, allowing it to trap sub-micron dust that standard “dry” or surface-tacky filters often miss.
