Delavan Recomends
« on: January 02, 2009, 11:03:37 pm »
manufacturers attach strainers to the nozzles
during assembly. The hole size in these
strainers is selected to fit the particular size of
nozzle in question. For example, it is common
practice to use 200 mesh strainers (hole size
.0029" square) on nozzles under 1.00 GPH.
Nozzles from 1.00 GPH through 1.35 GPH
are equipped with 120 mesh screen (hole size
.0043" square). Nozzles above 1.35 GPH are
equipped with 100 mesh strainers (hole size
.0055" square). On small nozzles it is
advisable to use a filtering medium which is
finer than any of the screens available and for
that purpose nozzle filters are available with
openings .0013, .0020, and .0025. These will
provide a degree of protection which will
insure greater burner efficiency over a longer
period of time because when plugging occurs
it is the filter and not the nozzle which is
affected.

This is a very old posting, but I be curious.
 ;D
Did you mean De Laval, rather than "Delavan"?  Or is that another brand?

The US Navy uses 2 brands of filters.  We had De Laval filters in both engine rooms aboard USS Duluth (LPD-6).
  It's my understanding they also manufacture filters for dairy use.

Shalom!
