METCLEAN PSA Filter Base Protector: Secure Monolith Stabilization for Professional DPF Restorations
The METCLEAN PSA Filter Base Protector is a heavy-duty, professional-grade workshop tool designed to clamp securely onto the base of split-type Peugeot-Citroën (PSA) DPF filters. It guarantees the internal ceramic monolith remains safely locked in position during high-flow hydraulic cleaning, preventing shifting, bypass channeling, and structural core damage.
As leaders in diagnostic tuning and emissions restoration, Mobile Eco Tuning (MET) developed this specialized tooling to solve a critical issue faced daily in our own UK HQ workshop and by our extensive network of 800+ active dealer agents. Developed in close collaboration with leading DPF cleaning equipment manufacturers, this tool is the definitive answer to safe, damage-free PSA filter restoration.
The Hidden Danger of Split-Type PSA DPF Wet Cleaning
Unlike solid-cased diesel particulate filters, split-type PSA DPFs feature a multi-piece modular housing. Inside, the delicate silicon carbide (SiC) or cordierite monolith relies on a compression gasket and a tight mechanical seat to prevent exhaust gas bypass.
When these filters are subjected to the rigorous hydraulic pressure and chemical flushing of professional DPF cleaning machines, the water column exerts immense physical force directly against the core. Without physical stabilization, the monolith easily shifts out of alignment—sometimes by only a few millimeters. This displacement compromises the edge seals, creating an path of least resistance (bypass channeling) that renders the filter useless post-installation, leading to immediate differential pressure fault codes (e.g., P242F or P2002) and engine management lights.
Engineered for Workshop Speed and Absolute Security
The METCLEAN PSA Filter Base Protector clamps firmly around the bottom lip of the split filter module. It creates an immovable mechanical barrier that supports the base of the brick directly against the cleaning pressure. Made from high-tensile, chemical-resistant alloy, this tool allows operators to carry out hydraulic flushes with absolute confidence, eliminating the risk of costly replacements of fragile PSA filters.
Anti-Shifting Physical Lock
Provides solid axial support to the base of the monolith, ensuring the brick cannot slide, lift, or rotate under the force of pressurized liquid flushing.
Chemical & Corrosion Resistant
Protected by a specialized zinc-chromate coating designed to resist aggressive DPF cleaning chemicals, acidic soot-dissolvers, and hot water cycles.
Ergonomic Fast-Clamp Tech
Features a heavy-duty adjustment bolt with a high-torque grip interface, enabling technicians to mount and dismount the protector in under 30 seconds.

💡 Mobile Eco Tuning Pro Tip:
When servicing split-type PSA filters, even with our robust Base Protector installed, the delicate silicon carbide composition remains highly sensitive to thermal and mechanical shock. Our workshop team strongly advises running your cleaning machines for no longer than 5 minutes at a maximum pressure of 1 bar. Exceeding this threshold can lead to micro-fractures in the core channels, allowing particulates to bypass the filtration grid and trigger premature regeneration faults once returned to the vehicle.
