Frequently Asked Questions

Q1: What is the primary difference between HEPA and ULPA mini-pleat filters?

While HEPA filters target 0.3um particles, our ULPA mini-pleat filter is engineered for extreme filtration grades (U15/U16), achieving 99.99995% efficiency @ 0.12um to protect the most sensitive microelectronics.

Q2: Why is “Hot-melt” technology critical for semiconductor cleanrooms?

Traditional aluminum separators can shed microscopic metal fragments. Our advanced hot-melt separator eliminates this risk, ensuring zero metal shedding which is vital for LCD/OLED display and wafer production.

Q3: How do you ensure the filter does not leak during terminal air supply?

Each unit is individually tested using precision scanning to guarantee zero leaks. Additionally, we use professional gel-glue (Polyurethane) to create a hermetic seal with the frame.

Q4: Can these filters be used in high-precision optical labs?

 Yes, they are highly recommended for optical instrument labs and aerospace engineering where maintaining good uniformity winds and sub-micron air purity is essential for instrument accuracy.

Q5: What are the size options for the external frame?

We offer high-precision aluminum alloy profiles in standard thicknesses of 50mm, 69mm, and 90mm to fit various FFU and ceiling grid configurations
