Dorr-Oliver Cyclone
A Dorr-Oliver cyclone is shipped with the instrument. The Dorr-Oliver
cyclone removes particles over 4.0 µm in size. The Dorr-Oliver cyclone is
attached to the instrument by sliding the cyclone clip over the protruding
catch. The tube from the Dorr-Oliver cyclone needs to be routed to the inlet
of the instrument.

Inlet attachments (impactors or inlet cap) should
not
be used when using the

The instrument flow rate must be changed to
1.7 L/min when using the Dorr-Oliver Cyclone in order to achieve a
4 µm (respirable) cut-point.
