High Output PSL Particle Generator
The High Output Polystyrene Latex (PSL) Particle Generator is designed for HEPA/ULPA filter testing, leak detection, and cleanroom certification. The instrument produces monodisperse PSL aerosol particles with stable and repeatable output, providing reliable particle concentrations for filter efficiency verification.
It generates up to 7.2 × 10¹⁰ PSL spheres per minute at 0.12 μm, sufficient to produce downstream concentrations suitable for six-nine efficiency (99.9999%) ULPA filters. The generator features a high-purity stainless steel atomizer for easy cleaning and maintenance, and its high-efficiency design reduces PSL liquid consumption.
Application
The High Output PSL Particle Generator is suitable for:
Factory production testing of HEPA and ULPA filters
Acceptance testing of HEPA and ULPA filters at customer sites
Leak detection and filter scanning for repair
In-place testing of cleanroom filters for efficiency measurement
Standards
The generator is designed to meet general international standards for HEPA and ULPA filter testing and aerosol generation for particle counting, including ASTM F2189, IEST-RP-CC001, and related ISO standards.
