Customer need
Respirable or thoracic sampling needs an appropriate size-selective head and specified flow, in addition to a filter.
NOVEL · PRODUCT AND SYSTEM SOLUTIONS
Sensidyne GK2.69 Thoracic / Respirable Cyclone
Select thoracic sampling at 1.6 L/min or respirable sampling at 4.2 L/min with one 37 mm cyclone head.
Choose the Fraction Before Sampling
GK2.69 separates particles by aerodynamic size before collecting the selected fraction on a filter. The required fraction is selected by flow rate; the same sample does not separately quantify both fractions. A compatible Gilian or other personal sampling pump must maintain the selected flow against the filter pressure drop.

Sample the required aerosol fraction
Sensidyne GK2.69 Thoracic / Respirable Cyclone: selection starts with the measurement or system output your team needs for its decision.
Product output
At the correct flow, the cyclone supports collection of the intended fraction on the filter.
Decision supported
Select the head, pump and filter together and check the assembled train; thoracic and respirable settings are not interchangeable.
Why Use It?
Workplace exposure assessment can require the thoracic or respirable fraction rather than undifferentiated total dust. The filter and analytical method are selected for the substance; gravimetric dust mass alone does not identify crystalline silica or other specific constituents.
Setup and Flow Verification
Fit the filter-containing section of the three-piece cassette to the cyclone O-ring seat. Connect the cassette outlet to the pump, secure the head at the lapel and route the hose over the shoulder. Calibrate with a fresh filter and the complete train. Select 1.6 or 4.2 L/min for the intended fraction; consult the manual for connections, cleaning and pressure requirements.
Pump and Filter Compatibility
The manufacturer reports 11.5 cm H₂O pressure drop with a 37 mm GF/A glass-fibre filter at 4.2 L/min, and 3.4 cm H₂O at 1.6 L/min. A 0.8 µm MCE filter at 1.6 L/min is listed at 11.9 cm H₂O. These are specified filter/flow combinations, not a universal pressure drop for every membrane.
