Filtering with diatomaceous earth (D.E.)
results not just in clean water, but water that
really sparkles. That's because D.E. filters remove
particles as small as 3-5 microns. Even though
particles smaller than 40 microns can't be seen
with the naked eye, large quantities of these
microscopic contaminants have a very noticeable
effect on water clarity. And D.E. strips them
away.
 D.E.
filters not only filter better, they make your life
easier... if two goals are met. The first goal is
to maximize the filtration area. More filter area
means longer periods between cleanings. The second
is to design a system that requires the least amount
of pumping power to achieve the needed flow rate.
Lower pumping requirements mean lower utility
costs.
That's why all Pentair D.E. filters
feature curved grids to maximize surface area. It's
why their internal design has been refined to minimize
flow restrictions. No wonder more than 2 million
Pentair filters have been installed by pool professionals.
Crown Pools offers the STAR SYSTEM
by Pentair for aboveground pools, matching the efficient
STAR D.E. filter with a powerful DYNAMO pump for
a system that provides the most efficient D.E. filtration
available. For more information about the Star

Looking
for top-end aboveground filter performance with
the lowest maintenance? Look at a cartridge filter
system.
This long proven design uses special filter elements
to strip particles from pool water with great effectiveness…particles
as small as 10–25 microns in size (particles
smaller than 40 microns cannot be seen by the human
eye).
Maintenance? Open the top. Remove the cartridge.
Hose it off. That's it.
All
cartridge filters aren't the same. And the secret
to the most effective filters is the design and
consistency of the cartridge itself. Are the materials
manufactured for the utmost consistency of all
surfaces to block and trap the maximum amount of
solids? Are the most durable materials used to
maximize the cartridge's life? Is maximum surface
area designed in to capture the most dirt and provide
the longest periods between cleanings?
 All Pentair filters feature cartridges made to
demanding specifications under the strictest quality
control standards to make certain they produce
the cleanest and clearest water while standing
up for the long run.
Crown Pools offers the CLEAN
AND CLEAR and the PREDATOR
II by Pentair. For more

SAND filters are one of the
most popular ways to filter water. They are simple,
effective, and require very little attention. Pool
water is routed through a sand-filled pressure vessel.
Over time, dirt accumulates in the spaces between
the sand particles, causing the pressure in the vessel
to rise as water finds it harder to pass through.  This signals
you to "backwash" the filter.
Simply reverse the water flow and "knock out" the
dirt. What could be simpler? But all SAND filters
are not created equal. For optimum filtration, all
the water must flow through the same amount of sand
at the proper rate.
That's why all Pentair sand
filters feature a special internal design that
keeps the sand bed level, ensures even water flow,
and results in the most efficient filtration possible.
That's why more than 2,000,000 Pentair filters
have been installed worldwide.
Crown Pools offers the The
SAND DOLLAR sand filter system for aboveground
pools, combining the efficient
SAND DOLLAR sand filter with
a powerful and reliable DYNAMO pump
to provide, trouble-free filtration, ease of maintenance,
and long life. For more information about the Sand
Dollar System, please click the image above.
