Together with Arcadis and Kenbri Fire Fighting, Comprex® enables complete cleaning and decontamination of PFAS-containing foam fire suppression systems.
This is how the switch to fluorine-free foams (F3) succeeds – legally compliant, documented and sustainable.
Why PFAS removal can’t wait
PFAS (“per- and polyfluorinated alkyl compounds”) are among the so-called forever chemicals. They are contained in older AFFF foam concentrates and can cause long-term harm to humans and the environment. The EU is planning a far-reaching ban on these substances, and foam concentrates containing PFAS may soon no longer be permitted in many applications.
This means for operators of fire suppression systems:
Old AFFF foam concentrate must be properly disposed of.
Systems must be thoroughly cleaned and decontaminated before fluorine-free foam concentrates (F3) can be used.
Documentation of cleaning is mandatory for authorities and insurers.
We support you every step of the way – from analysis to cleaning to the certified conversion of your fire suppression system.
Strong partnership for reliable results
Three specialists work hand in hand on PFAS decontamination:
- Comprex® ensures the mechanical deep cleaning of the pipe network with air-water impulses.
- Arcadis supplies Fluorofighter®, the chemical component that reliably dissolves PFAS residues.
- Kenbri Fire Fighting contributes its expertise in foam concentrate technology, mixers and recommissioning.

Together we implement a two-stage cleaning process:
Pre-cleaning with Comprex®
The system is completely flushed, old foam concentrate residues and loose deposits are removed.
Deep Clean with Comprex® + Fluorofighter®
The system is flushed at elevated temperature with chemical support to completely remove even persistent PFAS residues.
The result is a fully coordinated process that removes all residues from the system – documented, tested and ready for the use of fluorine-free foams.

Scientifically sound, proven in practice
Our cleaning principle is based on the Sinner’s circle – the interplay of mechanics, chemistry, temperature and time.
While conventional water flushes only rely on time and flow, our method makes targeted use of all four effective factors: Mechanics through the Comprex® impulses, chemistry through Fluorofighter®, increased temperature for intensification – and optimized flushing time for maximum effect.
The result: fast, deep cleaning with minimal water consumption, ideal for PFAS-contaminated foam fire suppression systems.
Advantages at a glance
Comprex® dissolves deposits and PFAS films using impulse energy, while Fluorofighter® breaks the chemical bond of the residues.
Partially filled pipes and pulsating flow ensure intensive flushing without long downtimes.
All flushing media are collected, filtered and disposed of properly.
After cleaning, the result is confirmed by laboratory analysis. The risk of a rebound is also significantly reduced by removing the contaminated sites in the PreClean phase.
Every cleaning is monitored, logged and documented in a traceable manner.
