Hayward Pro Series S311SXV 31" Top Mount pool sand filters utilize precision
engineered umbrella-fold self-cleaning laterals to provide efficient flow and
evenly distributed water for totally balanced back-washing and long lasting
performance. Pro Series swimming pool filters are
constructed with a corrosion-proof polymeric material that is designed to last
for decades, providing only the finest in water clarity for an enhanced
swimming experience.
Swimming pool sand filtration is the oldest and most popular
method of filtration for pools and spas. Water flows internally from top of the
filter to bottom during normal filtration cycles and use a multi-lateral system
in the bottom of the filter to return clean, clear refreshing water back to the
pool or spa.
Sand pool filters generally use #20 silica sand which is
approximately .40 to .55 mm. As water passes from the top of the filter to the
bottom particles of dirt and debris collect on top of and in the sand bed. The
filter does need to be cleaned on a normal basis by simply reversing the water
flow through the sand. This is usually achieved with a multi-port valve on top
of or on the side of the filter.
For crystal clear, sparkling water with minimum care, Pro
Series filters set a new standard for performance,
value and dependability. Choose what the Pro’s choose… Pro Series sand swimming
pool filters.
