Pleated Filter Cartridges
Greater surface area for longer life and
reduced filtration costs.
Watts Pleated filter cartridges outperform wound, spun, melt
blown, resin bonded, and other ”depth” type filter elements
because of our high surface area.
Lower pressure drop is another significant advantage. Using
pleated cartridges allows for increased flow rates and the use
of smaller filter housings to reduce capital equipment costs.
Further savings are provided because our 100% synthetic
filter media is cleanable, 5 micron and up, to lower cartridge
replacement costs. Pleated filter cartridges outperform other
pleated elements because our high-performance filter media is
systematically produced using 100% synthetic fibers, with no
binders or additives to leave a residue, foam or contaminate.
Our filter media is dramatically thicker than other products.
For this reason, Pleated cartridges provide “depth” filtration for
greater sediment removal, along with more surface area.

Pleated Filter Cartridges

Features
• Filter media is pleated for greater surface area
• Synthetic filter media is cellulose-free
• “Thicker” filter media has a greater capacity to capture and
retain particles, compared to thin, more rigid media types,
which have less void space for particle retention
• One micron absolute and 0.35 media use a
multi-ply laminate for superior performance
• Long lengths have netting to hold pleats in place
• All cartridge types and lengths are wrapped
• Full product line (Large selection of types, lengths &
micron ratings)
• Low pressure drop, long life, and reduced filtration costs,
compared to wound and spun cartridges
• No additives or binders, which may cause foaming
• Increased dirt holding capacity, longer life, fewer
cartridge replacements needed, and reduced filtration costs,
compared to other pleated cartridge suppliers
• Increased particle removal efficiency
• Superior performance and appearance
A multi-ply laminate is used with our sub and one micron
absolute grades for longer life and greater solids removal.
Note: Do not use with water that is microbiologically unsafe or
of unknown quality without adequate disinfection before or after
the system.

Lower pressure drop for higher flow rates
These cartridges are pleated, so initial pressure drop is significantly less compared to depth cartridges, such as wound,
spun, melt blown and resin bonded. As a result, higher flow
rates are possible, reducing filter housing size requirements to
lower capital equipment costs.

Washable & reusable
Our cartridges (5 micron and
up) are washable and reusable, to reduce filtration costs.
For best results, direct spray
into pleats to dislodge sediment. Or, let dry and brush
off filter cake from surface of
the media.
All cartridges
are individually
shrink wrapped
for purity
