Two-Stage Aerosol Collector
The SASS® 4100 is a highly efficient, two-stage filter-based aerosol collection device. It is the highest-capacity portable aerosol dry collector in production. Many applications require the collection and analysis of aerosol particles, ranging from environmental air sampling and counter-terrorism to epidemiology, medicine, and agriculture. These applications typically involve the monitoring or collection of airborne plant, animal or human pathogens. But aerosol sample analysis is frequently plagued by three problems:
- The targeted pathogen is present at a very low concentration
- The collection process involves too small an air sample to be statistically valid
- Available bioassay methods are not sensitive enough
By concentrating the sampled air, the SASS 4100 overcomes these problems.
Ultimate High-Capacity Aerosol Collection
At 4,000 LPM, the SASS 4100 two-stage collector captures and concentrates even the sparsest aerosol particles.
Ideal for Field Use in Any Weather
Compact, lightweight and portable, and tough enough for use even in wet or freezing weather conditions.
Biological or Radiological Sampling
Efficiently collects either biological or radiological samples with just a change of filter.
- No moving parts, other than the primary fan
- Maintenance is minimal
- Wide operating temperature range
- Structure is comparatively clog resistant
- Sampled air volume is maximized, improving collection statistics
- User-specified automated protocols
- Wireless control option
- Long-life primary and rechargeable battery options
- Easy decontamination, including fan rotor
- Compact and lightweight
- Air quality
- Public health
- Medical facilities
- Homeland security
- Power plants
