The pre-filtration box is an essential accessory for PETRO-PLUG® filter cartridges. It is placed on the top of the filter cartridge to protect it from impurities in the water (dust, sand, leaves, sludge, etc.) and to ensure its proper functionning.

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.
Use and design:
The THPP pre-filter box is always placed in the retention area at the point of entry of water into the filter. The internal foams of the pre-filtration box are to be washed with clear water as many times as required by the place of use, the frequency of rinsing depending on the quantity of impurities brought by the environment in which it is installed the filer.
Made of aluminium, the THPP box is filled with foam and geotextile that filter and trap impurities in the water. The THPP is designed to equip only one PETRO-PLUG® filter. Its diameter should be chosen according to the diameter of the filter it covers. For another configuration, other models of pre-filtration boxes are available : please consult us.
Installation & maintenance:
The pre-filtration box THPP must be installed above the filters PETRO-PLUG® by screwing it to the floor. The equipment should be cleaned at least once a year by rinsing with clean water. In difficult conditions (important presence of leaves, dust, sand or any other element that can block the pre-filtration system), maintenance must be carried out more regularly. Without major incidents, it is recommended to change the internal components every 5 years.
Box delivered without screws and fixing to the ground, as these accessories depend on the location of the installation and the thickness of the concrete.
The THPP pre-filtration box is composed:
- 1 metalic pre-filtration box
- 1 black mesh reinforced sheet
- 1 white foam floss.

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 markets its patented Petro-Barrier, Petro-Plug and Petro-Pipe 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.
