Frequently Asked Questions
Q1: Is the 93mm frame thickness compatible with all standard FFU units?
Yes, our 93mm slim aluminum frame is precision-engineered to integrate perfectly with most standard FFU (Fan Filter Units) and knife-edge ceiling grids.
Q2: How does the “blue jelly gel” improve the sealing compared to traditional methods?
The specialized blue jelly gel sealant creates a permanent elastic seal within the gel-groove design. This ensures a 100% leak-free connection with the knife-edge frame, eliminating air bypass risks.
Q3: Can this filter provide enough air volume for large industrial workshops?
Absolutely. The filter supports a rated air flow of up to 1800m³/h per unit, making it a scalable and powerful solution for large-scale industrial purification.
Q4: Why is “Good Uniformity Winds” important for SMT and PCB assembly?
In electronics SMT lines, air turbulence can disturb small components. Our design ensures good uniformity winds, providing stable laminar airflow that protects high-density PCB assembly from dust defects.
Q5: Is the aluminum frame resistant to humidity and oxidation?
Yes, we use an anodized aluminum alloy steel casing that effectively resists oxidation. This makes the filter durable for years of use in varied environments, including high-humidity research labs.
