Note : SidePak built-in impactors must be operated with the flow rate
set to 1.7 L/min for proper performance. Using other flow rates
will result in unknown particle size fractions. The standard inlet
can be used at any flow rate.
Always use the standard (unmarked) inlet when sampling
through an external size-selective sampler such as a cyclone
or external impactor.
SidePak size-selective inlets use an internal impactor insert with two
O-rings. This component functions as a collection plate where
particles larger than the cut-size are trapped. The same insert is used
for all impactors, but it is
not used at all for the standard inlet .
To make sure unwanted (large) particles remain trapped on the
insert, it is necessary to apply a small amount of
impactor grease
(vacuum grease) for the particle to stick to. Grease is also applied to
the O-rings to aid assembly and improve sealing.
Note : Size-selective impactors will not function unless an impactor
insert is installed. To ensure proper performance, the impactor
insert should be removed, cleaned and regreased prior to each
use.
1. Remove the impactor by loosening the two captive screws that
hold the impactor in place.
