U16

U16 filters are commonly applied in advanced manufacturing and research environments where air cleanliness must be maintained at extremely low particle concentrations.

They provide an additional margin of protection compared to U15, supporting tighter process control and higher consistency.

This grade is selected when cleanroom performance requirements approach the upper limits of ULPA filtration without reaching the most extreme classification.

Typical Applications

U16 ULPA filters are used in environments with extremely stringent air cleanliness requirements.

Common applications include:

• Advanced semiconductor fabrication facilities

• Nanotechnology and microelectronics cleanrooms

• High-precision optical and photonics manufacturing

• Sensitive materials research laboratories

• Critical zones within leading-edge production environments

In these applications, U16 filters help maintain ultra-clean airflow conditions and protect highly sensitive processes.

Performance Highlights

U16 filters are engineered to deliver exceptional filtration performance for advanced cleanroom systems.

Key performance characteristics include:

• ULPA filtration tested according to EN 1822

• Extremely high particle removal efficiency at MPPS

• Mandatory individual efficiency testing and leak scanning

• Stable pressure drop suitable for engineered cleanroom airflow

• Consistent performance throughout the filter service life

These characteristics make U16 filters suitable for applications requiring extreme cleanliness and operational reliability.

FAQ

How does U16 differ from U15 ULPA filtration?

U16 filters provide a higher level of particle removal efficiency than U15 filters, making them suitable for environments with more stringent cleanliness requirements and tighter process control.

Are U16 filters necessary for most cleanroom applications?

No. U16 filters are typically used only in highly advanced cleanrooms where lower ULPA or HEPA grades cannot meet contamination control requirements.

Can U16 filters be integrated into standard cleanroom systems?

U16 filters can be integrated into engineered cleanroom systems designed to accommodate higher pressure drop and tighter airflow control. System design considerations are essential.

Do U16 ULPA filters require individual testing?

Yes. Under EN 1822, U16 filters undergo individual efficiency testing and comprehensive leak scanning to verify filtration performance and integrity.
