The Sharp Cut Cyclone (SCC) 1.829 and SCC2.654
The SCC 1.829 was primarily designed for photometer applications at 5 Lpm for a PM2.5 cut. Similarly, the SCC 2.654 has the same performance at 10 Lpm. The SCC series of cyclones has been intensively developed and is the subject of two, peer-reviewed papers1,2. The model's performance is highly predictable and several other cut points can be predicted with either cyclone.
Another feature of the SCC model is their very low pressure drop at design flow rates, the details of which are specified in the instruction manual. The photometer with which the cyclones may be utilized must have a vertical inlet tube of ½ inch O.D. The cyclone is held to this tube a by a pair of internal "O" rings. Additionally the cleaning frequency of the SCC is greater than 30 days of continuous operation, which is desirable for continuous particulate monitors.

Latter additions to this line of Cyclones are the SCC 0.732 and SCC 1.197. These were primarily designed as PM1 Cyclones for Diesel soot sampling applications. They are identical in appearance to the previous units illustrated except that the diameter of the tube used in the outlet socket must be 3/8" Outside Diameter.
The range of performance point with these cyclones cover the principle health related range of interest.
