SASS 3100 Dry Air Sampler

The SASS® 3100 Smart Air Sampler System is a compact, rugged microprocessor‐controlled portable air sampler designed for use with state‐of‐ the‐art electret filter media. It is highly suited to the collection of biological and radioactive aerosols. In independent tests performed by third parties, it has out‐performed all competitors in terms of collection efficiency and suitability. The standard 44mm diameter electret filter used with the SASS 3100 samples at a maximum rate of 300 liters/minute and has a collection efficiency of 50% at an aerosol particle diameter of 0.5 microns. A second HEPA‐style electret filter that is physically interchangeable has 95%+ collection efficiency for particles greater than 0.3 microns in diameter. It has a maximum sampling rate is 49 liters/minute‐ a very high rate for a HEPA‐style filter of this size. For users interested in collecting radioactive aerosols, the HEPA‐style filter meets all key international standards for radioaerosol collection. Flow rates and sampling protocols are microprocessor controlled and may be pre‐ programmed for different types of field work using a bundled PC software package. The unit can be operated in local mode wherein the user turns the fan on and off manually or it can also be operated remotely via an RS232 serial link. For applications where run‐to‐run cross‐contamination is a serious concern, the filter mounting structure may be removed and cleaned as a separate component. The motor/rotor assembly may also be removed and the rotor cleaned. Field operation may be powered by either a primary or rechargeable battery. The primary battery provides over 24 hours of continuous operation at maximum flow, while the rechargeable battery should power the device for about 20 hours. A universal wall‐plug power supply accepting 100‐240 V AC at 50‐60 Hz is also provided.
