Frequently Asked Questions
Q1: What are the advantages of choosing between Top and Side gel seal locations?
Our versatile sealing slots allow you to choose top or side liquid grooves. This ensures a perfect fit for specific terminal housings or FFU designs, making installation seamless in various cleanroom layouts.
Q2: Is the U16 ULPA filter really necessary for semiconductor fabrication?
Yes. In Wafer Fabrication and lithography, even 0.1um particles can cause fatal defects. Our U16 grade filter captures 99.99995% @ 0.12um, providing the extreme protection required for high yields.
Q3: How does the “non-volatile polyurethane gel” benefit my cleanroom?
The high-adhesion polyurethane gel we use is specially formulated to be non-volatile. This ensures no chemical off-gassing, maintaining the purity of the air in sensitive semiconductor and optical instrument labs.
Q4: Can this filter handle the high-volume air turnover in OLED production?
Absolutely. While providing ultra-high efficiency, the filter is also rated for a high dust holding capacity of 1080g. This extends the service life and maintains consistent airflow in demanding LCD/OLED display lines.
Q5: Are the face guards essential for mini-pleat ULPA filters?
We highly recommend the optional double-sided face guards. Mini-pleat ULPA media is extremely fragile; these guards prevent accidental damage during installation, ensuring the hermetic seal and efficiency remain intact.
