Dust extraction cleaning removes accumulated material from agreed hoods, ducts and collector sections. We work where deposits are restricting access for maintenance or need removing from the extraction route. Cleaning the outside of a collector leaves the condition of its internal air path unresolved.
Dust Extraction Cleaning
Dust extraction cleaning for accessible hoods, ducts and collectors, with controlled dust recovery and clear separation from LEV testing.

Hoods, ducts and collector sections
Hoods, duct bends and collector hoppers can retain different quantities of material.
Dust containment
Internal cleaning uses suitable isolation and controlled recovery so deposits are not spread into production areas.
Hoods, ducts and collector sections
Hoods, duct bends and collector hoppers can retain different quantities of material. The dust hazard determines the collection method and ignition precautions. Filters may need replacement rather than washing, according to their design. We use existing access points and identify further access needs without treating unseen sections as part of a completed clean.

Isolation and controlled dust recovery
The system needs suitable isolation before internal access. Dust is contained during pickup and container handling, with protection for adjacent production. The method considers combustible dust as well as exposure, because an effective filter alone does not settle equipment suitability.
Cleaning versus LEV performance
We identify the sections cleaned and any maintenance concerns exposed. Where extraction controls exposure to hazardous substances under COSHH, deposit removal does not replace the required thorough examination and test of the LEV system. That test considers performance, including whether the system captures the process contaminant effectively. We keep cleaning findings clear so maintenance can arrange the appropriate next checks.
Cleaning is carried out without altering damper positions or extraction settings; those controls remain part of the system’s maintenance.
Dust Extraction Cleaning: common questions
Does cleaning count as the required LEV test?
No. Where LEV controls hazardous-substance exposure under COSHH, thorough examination and testing assess its performance separately from cleaning.
Are filters always cleaned rather than replaced?
Filter design and manufacturer guidance determine whether cleaning or replacement is appropriate.
Can blocked extraction be left running during internal cleaning?
Internal access needs suitable isolation; continued operation must not be assumed safe.
Are collector hoppers part of the clean?
They can be included when the contents and access are assessed and agreed.
Can cleaning alter dampers or extraction settings?
Cleaning should not change system settings unintentionally. Performance and settings are checked through the appropriate maintenance and LEV testing.
