Kit PETRO-PIT® 410 Complete hydrocarbon filtration system


PETRO PIT filtration kit for retention tanks and pits

The PETRO-PIT®  410 filtration kit has been developed for quick and easy installation of the PETRO-PIT 410 filter cartridge with its PFC 44 pre-filter on a retention tank outlet. Its self-locking system traps harmful hydrocarbons, preventing soil pollution. Its oleophilic and hydrophobic polymer component permanently traps hydrocarbons.




The PETRO-PIT-410 Kit is an innovation invented by SPI® in the 1990s for easy adaptation to all types of retention tanks and pits. It continuously filters drainage water while trapping harmful hydrocarbons, preventing soil pollution in compliance with standard EN 858-1 and the French Water Act, with a discharge rate of less than 5ppm. It also complies with paragraph 471 of NF C13-200 (“All precautions must be taken to ensure that the recovery tank does not fill with water or that water is evacuated“). Our filters and pre-filters are regularly tested in independent laboratories, when new, in half-life conditions and after their recommended period of use (see Additional Information tab).

In the event of a major hydrocarbon spill, the component reacts and forms a plug, preventing any fluid from spilling into the environment. It is a self-locking system, operating without any mechanical parts or electrical connections.

This kit contains :

  • 1 stainless steel 90° elbow, 1.5″ female outlet, to be screwed onto the retention,
  • 1 stainless steel 1.5″ 1/4-turn valve,
  • 1 PFC-44 pre-filter,
  • 1 PETRO-PIT-410 filter for non-specific hydrocarbons,
  • 1 roll of Teflon for watertightness.

Description of the PETRO PIT® 410 kit:

  • Made from rigid PVC with UV protection for extra strength and durability.
  • Hydrophobic, oleophilic polymer component: permanently locks in hydrocarbons.
  • Approximate flow rate filtered (*): approximately 3 to 5 L/min / Approximate saturation (*): 1L / Recommended change (*): every 1 to 3 years

(*) Depending on the conditions of use at each site, depending on the quantity of traces of hydrocarbons filtered by the cartridge, the regularity of maintenance of the tank/pit/prefilters, etc. Conditions of use for which SANERGRID® and SPI® cannot make any commitment.

SPI filters have been recognized for over 30 years for their high reliability, extreme robustness and longevity, even under the most difficult conditions: resistance to hot transformer oils (>100°C), water emulsified with dielectric oil, high resistance to ultra-violet rays and thermal amplitudes, etc. SPI has ISO 9001 quality certification for its production process, and has integrated an eco-design approach aimed at reducing the amount of material and CO2 used during the manufacturing process.

Accessories and options

  • The PETRO-PIT + PFC-44 set can be completed with a PFB-0810 type pre-filtration grid placed inside the retention tank.
  • The pre-filter foams can also be refilled on site. Thanks to these two refillable innovations, you can reduce the amount of waste generated by more than 50% for the same maintenance scope.

The PETRO-PIT® range is the only range on the market that offers all the references depending on the use and type of pollutant: hydrocarbons, synthetic and natural esters or oils, etc. The choice of cartridge format also depends on the flow rate.

Use and maintenance

All industrial equipment or storage units containing hydrocarbons must be fitted with retention tanks.


  • The filter is screwed onto a 1.5″ female connector on the valve outlet provided for this purpose (at the customer’s expense). The use of Teflon or sealant on the threads is recommended to ensure complete watertightness.
  • The filter should be positioned horizontally or slightly inclined in the direction of flow.
  • An optional PFC44 pre-filter for PETRO-PIT® can be installed upstream of the filter to remove impurities from the water and prevent the filter from clogging up too quickly.


  • SPI filters are sensitive to sludge and impurities carried by the water, which can considerably reduce the flow rate or even block the filter. Good pre-filtration is therefore essential to protect the filter inlet, and should be checked regularly. The pre-filter should be washed with clean water as often as required by the place of use, the frequency of rinsing depending on the quantity of impurities carried to each drainage point.
  • To keep track of your filters and replacement schedules, SPI products have a batch serial number corresponding to the batch of active ingredient tested and approved by the manufacturer. So you too can track your filters and recommended replacement dates simply by visual inspection.
  • At the end of their life, the filter and pre-filter should be disposed of as conventional hydrocarbon waste under code [150202*].

For your specific needs in terms of traceability and automatic reminders of your maintenance dates, SANERGRID® can set up a unit tracking system for you, in return for a maintenance contract with one of our national partners.

Additional information

The PETRO-PIT® range, part of the SPI® filter technology, is the European benchmark for rainwater filter cartridges contaminated with hydrocarbons for small-volume hydrocarbon retention. It is the only filter on the market that has been validated for over 30 years by the largest French and European industrial companies (EDF, ENEDIS, SNCF, SCHNEIDER, RTE, ABB HITACHI, SIEMENS, IBERDROLA, NATURGY, REE, EDP, ENEL, IREN, TERNA, E-ON, RWE, VATTENFALL, ELIA, ESB, SCOTTISH POWER, NATIONAL GRID, NETWORK RAIL, UK PN, BRITISH PETROLEUM, TOTAL ENERGIE, BASF, BAYER, ELES, CERN, ITER, VOLVO, DEUTSCHE BAHN, ADIF, SNCB, REPSOL, etc… non-exhaustive list).

Rainwater drainage and hydrocarbon pollution: thanks to the SPI anti hydrocarbons filter system, the tank is empty of water most of the time and ready to receive hydrocarbons. In compliance with water legislation, the water discharged from the tanks is not contaminated with more than 5 ppm of hydrocarbons, in accordance with standard EN 858-1 (“light liquid separation installations”).

SPI filters® are regularly tested by independent laboratories: SANERGRID Bureau Veritas report certified COFRAC I.D.: 003606/2776443/1/1/1 in 2015 (France), SPI Phoenix laboratory reports I.D.: AR67044 in 2002, 2004, 2005, 2009, 2018, 2022 (USA), TÜV report Nr 2432974 in 2016 (Germany), NUA report -Z-11895-1/1-2016.
