RED SERIES
PURPLE SERIES
PLEATED POLYPROPYLENE - COMMERCIAL PLUS SYSTEMS - (RED SERIES)
The Red series filters offer high flow rate pleated filtration solutions with extended life, available in 1
absolute, 5, 20, 50, and 150 microns, plus an activated carbon (PAC) solution. Designed for flow rates
up to 150 GPM (568 LPM) with low pressure drop, these filters excel in turbidity applications, effectively
removing silt, rust, and other particles. Their large filtration area enhances contact time for improved
water quality and system longevity. Serving as a direct replacement for costly stainless steel housings,
they are ideal as polishing or pre-filters in high-capacity applications. Made from 100% cellulose-free
media, they are cleanable from 5 microns and up, representing the future of commercial filtration.

MELTBLOWN POLYPROPYLENE DEPTH - COMMERCIAL PLUS SYSTEMS - (PURPLE SERIES)
The Purple series filters are high flow rate meltblown polypropylene solutions with extended life,
available in 5 and 20 microns. Their large surface area depth filtration design enables flow rates
up to 100 GPM (380 LPM) with low pressure drop, effectively outperforming competitors in turbidity
applications like silt and rust removal. The design promotes lower shear water velocity, enhancing
contact time for better water quality and longer system life. These filters serve as a direct replacement
for costly stainless steel housings and are ideal as polishing or pre-filters in high-capacity applications.
Made from 100% polypropylene media, they represent the future of commercial filtration.

ENPRESS™ PIONEER® Certified POE Filtration System
The PIONEER® System features the ENPRESS™ E3-M® Filtration System, which includes an exclusive
integrated bypass and meter that utilizes industry standard threaded fitting kit connections to simplify
installation and streamline field-installation inventory requirements.
This system comes standard with a 1" MNPT elbow or straight connectors to the bypass and requires no
gluing. A metered Umbrella Cap® is now included with every system, along with a 3/8" fitting and shutoff integrated into the inlet side to allow rapid tubing connection for draining of the system of sediment
and water during filter change out.
The PIONEER® system is a superior alternative to small and inefficient traditional 2.5" or 4.5" housings,
or expensive stainless steel cartridge housings, and is an NSF 61 and 44 listed device. Six filtration
series options are currently available: green, orange, yellow, blue, white and silver and PIONEER®. Each
“series” offers unique filtration capacities and flow rates from residential requirements up to 60 gpm.
Each filter comes with a unique handle designed top cap for lightweight and easy removal, a bag for
proper disposal, and a double O-ring seal.
The ENPRESS™ Cartridge Tank is specifically designed for residential, light commercial, and commercial
point-of-entry (POE) installations and applications. The patented and patent pending ENPRESS™
Cartridge Tank filtration systems and filters feature an easy to access top and bottom opening for use
with multiple filtration connections and solutions, in a lightweight and cost-effective package. With
multiple configuration options, this is the filtration solution of the future...100% non-metallic!
