Part of the technology SPI®, the SPI® esters range is the United Kingdom and European reference for filtration cartridges for rainwater contaminated with by natural esters for small retention volumes.

Made out of PVC to ensure better resistance through time, the P-PIT416-FR3 is a cartridge specially designed to any type of tank. It ensure filtration of rainwater drainage, while blocking vegetal oils type FR3 and MIDEL EN: it therefore, forbid any ground contamination. 

The filtered flow rate is approximately 1.5l/min and should be changed every 1 to 3 years. The active media into the filter is a mix of different oleophilic and hydrophobic polymer components which trap definitely natural esters.
During a significant spill of vegetal oils, the components react and form a plug, preventing any fluide from discharging into the environment: the system is self-locking and works whithout mechanical parts, nor electrical connection.

Patented system, ideal for outdoor retention tanks (flexiblemetallic or concrete). Can be used horizontally or slightly inclined in the direction of flow.

A pre-filter PFC44 is highly recommended to avoid filter P-PIT to be clogged by impurities of the water.

Make installation easier by choosing the PETRO-PIT® SET to fit any low point and drain valve. This set includes filter, pre-filter, valve, elbow and teflon roll.

The only filter on the market recognized from more than 15 years by the biggest UK and European industry (Network rail, Balfour Beatty, ABB, SIEMENS, SCHNEIDER…) and having passed successfully the test by independent laboratories such as Bureau Veritas or TUV with a esters rate in output of the filter below 5 ppm.

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.
