 6534
Filter Element Application
The 6534 is our most popular filter element. This
filter is a 4 segment element for use in our popular
1000 series filter housing as well as in equivalent
competitive housings. This filter is applicable to
the filtration of oils and has a nominal filtration
rating of 1-5 microns. Typical applications would
involve oils of 100 -500 SUS (30 - 100 Cst) at
temperatures up to 270 F.
DIRT HOLDING CAPACITY
In some applications COMO 6500 series filter
elements have demonstrated dirt-holding capacities
in excess of 40 pounds. However, in the typical
applications where a 6534 element would be used, a
solid contaminate loading of several pounds may be
anticipated. Since the solid holding capacity of an
element is determined by factors such as the element
configuration, fluid flow rate, particle size
distribution, cake porosity, water content, and
operating pressure, it is difficult to estimate the
ultimate filter element holding capacity for a
specific application.
WATER ABSORBENCY
6534 filter element typically will remove and retain
up to 1 gallon of water from hydraulic oils. At
Retention quantities up to .75 gallon, the oil
discharged from the filter will typically remain dry
even with wet oil in. This property makes COMO
filter elements ideal for hydraulic filtration
systems, especially for dirt and moisture intolerant
servo, precision, and high reliability hydraulic
systems.
BETA RATIO
Filtration beta ratios are not the best indication
of filter performance in multipass-bypass filtration
systems using depth type filters. Total filtration
system performance is determined more by total fluid
volume and flow rate through the filter system
rather than by filter beta ratio. In these types of
applications filtration performance is not
substantially enhanced by beta ratios over 10.

FLOW RATE
The recommended flow rate for the 6534 filter element is 2.5
G.P.M. in light hydraulic oil. In heavier oils, flow may be
.5 - 1.5 G.P.M. In very light oils, such as fuel oils, the
filters may be used at flow rates as high as 5 G.P.M. The
recommended rule of thumb is: the flow rate at normal
operating temperature should be such that the differential
filter pressure on a new element is in the range of 15-30
PSI. Selecting a combination of filters and flow rate to
yield results in this range will result in maximum filter
life.
