E-Series Prefilters with Cleanable Filter Elements
|
An E-Series Prefilter, installed in an EDM water circulation loop
between the pump and the existing disposable filters, can extend
the life of the disposable filters by at least 50%, or more if
the solids load is unusually heavy. The Keller permanent, cleanable
filter elements remove sludge and large solid particles from the
system, allowing the disposable elements to filter only fine particles.
An E-Series EDM Prefilter extends the life of disposable filters,
reduces the frequency of disposing of spent elements, and permits
longer machine run times. In addition, E-Series filters are convenient
prefilters and final filters for ion exchange resin beds, and
are excellent sediment and rust filters for the shop water supply.
How to Select the E-Series EDM Prefilter
|
| E-Series EDM Prefilters are supplied for three flow capacities:
|
|
XE10 - 25 gpm; XE20 - 50
gpm; XE22 - 100 gpm.
|
Select the prefilter assembly required
for the water recirculation rate of the machine. The XE assemblies
are supplied prepiped with inlet & outlet pressure gages,
shutoff valve, mounting bracket, and barbed fittings for 3/4"
or 1" hoses.
|
Installation & Operation
Install an E-Series Prefilter in the dirty water circulation
hose between the pump and the existing disposable filters, using
the 3/4" or 1" hose barbs provided. Clean the Keller
all-plastic filter elements by soaking in a dilute muriatic acid
solution or any other metal cleaner used in cleaning the EDM system.
All components in an XE assembly are acid-resistant plastic.
