Model 2045 Particle Generator Using Polystyrene Latex spheres

MSP Corp., M2045, High Output, PSL Particle Generator - Request a Quote

M2045, Particle GeneratorThe Model 2045 Particle Generator uses PSL spheres to provide a very high particle challenge to ULPA filters and HEPA filters. Polystyrene Latex spheres are used as the upstream particle challenge to measure filter efficiency of ULPA and HEPA filters and search for pin hole leaks across the filter surface. HEPA filters provide 4/9 and 5/9 filter efficiency, while ULPA filters offer 6/9 and 7/9 filter efficiency. The Model 2045 Particle Generator easily meets the upstream particle challenge, producing 7.2x10 E10 at 0.10μm particles per minute. Polystyrene Latex spheres at 0.3μm are used to challenge HEPA filters and detect pin hole leaks, while Polystyrene Latex spheres at 0.15μm or 0.12μm are used to challenge ULPA filters and detect pin hole leaks.

The upstream particle count of the filter challenge is extremely important, since a 6/9 ULPA filter has the capability to trap 99.9999% of all particles flowing through the filter, which is 1 particle out of 1 million particles trapped by the 6/9 ULPA filter. Thus a very high, upstream particle count of 7.2x10 E10 at 0.10μm particles per minute is needed to sustain the upstream particle challenge of a HEPA filter. The Model 2045 is the only Particle Generator to provide this high particle count challenge. The Polystyrene Latex spheres are mixed with the appropriate air flow volume, such as 700 CFM, 1000 CFM or 2000 CFM, which provides a uniform airflow to the upstream filter, while evaporating the DI water surrounding each Polystyrene Latex sphere prior to the upstream filter contact.
