The PFE-PWF external pre-filter cartridge is installed upstream of the PETRO-BARRIER™ PUMP filtration system in the PFE-MP block. It consists of a pleated polyester filter. Its function is to purify rainwater of fine particles that could clog the PETRO-BARRIER™ anti-hydrocarbons filtration cartridge.
The PFE-PWF pre-filter must be changed regurlaly to allow optimal drainage of the wastewater as soon as it is satured with sludge and particles.

Measure around the narrowest part of your natural waist, generally around the belly button. To ensure a comfortable fit, keep one finger between the measuring tape and your body.
To ensure that the PETRO-BARRIER™ Pumped filter maintains a sufficient flow rate, the external filter system must be kept as clean as possible. If there are too many impurities in the drainage water, the PFE-PWF pleated filter must be replaced by the PFE-MP. Sold in sets of 2.
SPI® has been an Eastern American manufacturer based in Connecticut for 30 years. Bill Gannon founded SPI® in 1991 to develop a technology for solidifying polluting oils. His experience as Vice President of Liquid Waste Technologies from 1985 to 1991 and the Exxon Valdez disaster in 1989 were key elements in the creation of SPI®.
In the early years, SPI® focused on waste treatment by creating solidifiers for oils (Oil Bond) and for water (WaterBond). Then, in the years that followed, SPI® naturally turned to pollution prevention.
SPI® offers its patented PETRO-PIT®, PETRO-PLUG®, PETRO-PIPE® and PETRO-BARRIER® products to all customers who need to secure their retention equipment with a passive and inexpensive solution, thus allowing good drainage of rainwater without risk of overflow and therefore pollution.
No oil has ever drained from any SPI® filter. SPI® filters comply with American EPA SPCC standards, European and French standards on water treatment in light hydrocarbon separators as well as the water law (hydrocarbon content of water at the filter outlet less than 5 ppm , ICPE compliant). For three decades, thousands of installations have been protected by SPI® products in North America, Europe and Latin America. Its approval with the largest petrochemical industries, power companies and local authorities gives it an obvious strength to innovate in the filtration and solidification of new pollutants (natural esters FR3-COPPER, synthetic esters MIDEL7131) and find the solution for which you need.
