High Output PSL Particle Generator

A high output polystyrene latex (PSL) aerosol generator for HEPA/ULPA filter testing, leak detection and cleanroom certification.
Generates up to 7.2×1010 PSL spheres per minute at 0.12 µm. Produces 1×108 PSL per cubic foot when injected into 720 cfm of air flow for testing 24”x48” filters at 90 ft/min face velocity, sufficient to produce a downstream concentration of 100 particles/ft3 for a six-nine efficiency (99.9999%) ULPA filter. Monodisperse size distribution with very few doublets and triplets. High efficiency atomizer reduces liquid consumption. Stable and repeatable operation. High purity, all stainless steel atomizer for easy cleaning and maintenance.
 
Features
1. Generates up to 7.2×10-10 PLS spheres per minute at 0.12 μm.
2. Monodispese size distribution minimal number of doublets and triplets present.
3. High efficiency atomizer reduces rate of liquid consumption and the cost of PSL solutions used.
4. Stable and repeatable operation.
5. High purity, all stainless steel atomizer for easy cleaning and maintenance.
6. Atomizer can be turned on and off just for the duration of the test to further reduce PSL liquid consumption (optional).
7. Remotely-operable atomizer allows easy integration into filter test systems (optional).

Applications
1. Production testing of HEPA and ULPA filter testing in the factory.
2. Acceptance testing of HEPA and ULPA filter at customer sites.
3. Filter scan to locate leaks for repair.
4. In place testing of HEPA and ULPA filters in the cleanroom for efficiency measurement and leak detection.
