The PTB-SF-24 internal pre-filter is an essential complement to PETRO-BARRIER™ Pumped filters. Placed in the upper part of the PTB-24 in the inlet chamber, upstream of the PTB-C-24 cartridge. The pre-filter protects them from small particles and impurities contained in the water (dust, sand, mud...).

The PTB-SF-24 internal pre-filter is essential for the proper operation of PETRO-BARRIER™ filters. The pre-filtration of the inlet water is crucial to avoid blocking the PTB too frequently with dust.
This system is ideal in civil engineering applications (retention basin, concrete pits, etc.).
Installation and maintenance:
The PTB-SF-24 is simply screwed on and off by opening the cover.
The internal foams of the pre-filter should be cleaned with clean water as often as required as the place of use. The frequency of rinsing depends on the amount of impurities brought into each drainage point.
In difficult conditions (significant presence of leaves, dust, sand or any other element that could clog the pre-filtration system), maintenance must be carried out more regularly. Without major incidents, it is strongly recommended to change the internal components every 3 years.
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.
