3–6 Series 3080 Electrostatic Classifiers
Exhaust Flow Fitting
The Exhaust Flow fitting is a
3
⁄8-in straight fitting that allows
connections for the bypass air exiting the Classifier for the Nano
DMA or for the sheath air flow for all DMAs. This fitting is left open
in Single Blower mode, or it is connected to the Excess Flow fitting
on the Classifier in Dual Blower mode. The connection can be made
with flexible conductive tubing or with Swagelok-type connections
and rigid tubing.
Bypass Flow Fittings
The Bypass Flow fittings are
3
⁄8-in straight fittings that allow
connections for bypass flow if available with your DMA. Typically,
the Model 3085 Nano DMA uses the bypass flow to bring aerosol to
the inlet slit faster to minimize ultrafine particle losses due to
diffusion. The Exhaust Flow port on the Classifier is usually left
open to exhaust the filtered bypass flow. The Bypass Flow fitting on
the Classifier can be connected to the Bypass Flow fitting on the
Nano DMA with flexible conductive tubing or with Swagelok-type
connections and rigid tubing. This bypass flow is up to 15 L/min.
This bypass flow normally is set between 10 and 15 L/min. The
BYPASS FLOW port on the Nano DMA is capped when bypass flow
is not used.
A second use of the bypass flow is to provide added flow for the
Model 3081 long DMA to reach flows up to 15 L/min or for Model
3085 Nano DMA to reach flows up to 20 L/min. The bypass can be
connected in series with the sheath flow to increase the sheath flow
rate.
Excess Flow Fitting
The Excess Flow fitting is a
3
⁄8-in straight fitting that allows
connections for the excess air exiting all DMAs. This fitting is either
connected to the Excess Flow fitting on the DMA in Single Blower
mode or to the Exhaust Flow fitting on the Classifier in Dual Blower
mode. The connection can be made with flexible conductive tubing
or with Swagelok-type connections and rigid tubing.
Sheath Flow Fitting
The Sheath Flow fitting is a
3
⁄8-in straight fitting that allows
connections for the sheath air used in all DMAs. This fitting is
connected to the Sheath Flow fitting on the DMA. The connection
can be made with flexible conductive tubing or with Swagelok-type
connections and rigid tubing.
