Introduction
Description
The GS-3 Cyclone is a 10-mm
lightweight conductive plastic
sampler with multiple inlets
that uses a standard three-piece
25 or 37-mm cassett e and fi lter for
collecting respirable dust particles.
The GS-3 Cyclone conforms to
the ISO 7708/CEN criteria of a
4-μm 50% cut-point at 2.75 L/min*
with minimum bias meeting the
performance criteria in OSHA's
final silica rule. Other flow rates
may be used to achieve cut-points
for alternative applications. The GS-3
Cyclone is supplied with cassette
adapter, bowl adapter, and grit pot.
* Calibrated at U.K. Health and Safety
Laboratories. Visit www.skcinc.com/

Nos. 225-100 and 225-103, respectively). Replacement cassett e adapters are available, allowing the user to adapt whichever model they are using to another cassett e size.
- Page 3 Prepare a cyclone/cassett e assembly (Figure 1). Ensure grit pot remains on cyclone body during calibration. SKC recommends using the smallest calibration jar possible. To achieve this, do NOT use Cassette Holder Cat. No. 225-1 during calibration. Place cyclone/cassett e assembly into an airtight calibration jar that contains an inlet and outlet (Cat.
