Installation
The Model C carbon filter can be
installed with, or in some cases, instead
of an existing dust filter. If the filter track
is 2” thick, it is often possible to slide in
a 1” prefilter and a 1” carbon filter.
Built-up filter banks with holding frames
are particularly easy to retrofit using
Model P fasteners. Model C carbon fil-
ters are ideal for use in the prefilter
track of the two-stage Sureseal filter
housing.
Notes:
1. Special size Model C filters are available. Contact your local representative or the factory.
2. Recommended maximum rated velocity is 500 fpm.
3. Pressure drop for clean Model C filters at 300 fpm face velocity is:
C50-1inch, .30 w.g. C50-2 inch, .25 w.g.
C75-1inch, .35 w.g. C75-2 inch, .30 w.g.
