Industrial Duct Cleaning & Process Extraction
Blocked extraction costs production time long before it becomes a compliance problem. Deduct cleans, clears and documents industrial ductwork around your shift pattern.
- Shutdown, night-shift and phased delivery
- Confined space and high-level access in house
- Process, dust, fume and weld extraction
- Urgent response for extraction failures
- 24–48h
- Urgent response window
- Shutdowns
- Planned programme delivery
- COSHH
- Supporting employer duties
- UK-wide
- Multi-plant contracts
Extraction that performs, evidence that satisfies
Industrial ductwork accumulates process residue, dust and fume deposits that reduce capture velocity, load the fan and increase fire risk in the duct run.
Deduct investigates the system before quoting: where is the restriction, what is the deposit, and how can it be reached safely. On several projects the reported symptom — poor extraction at the workstation — has come down to a fully blocked duct run some distance from the hood.
We clean using brushing, air lancing and negative pressure capture, then verify condition and record it photographically. Access panels are installed where none exist so the system can be maintained rather than repeatedly investigated.
Programmes are planned around production: phased by line, delivered on nights, or folded into scheduled shutdowns with permits, isolations and reinstatement agreed in advance.
Systems we clean
From general factory ventilation through to process extraction systems.
Process extraction ductwork
Production line extraction cleaned to restore designed airflow and reduce fan loading.
LEV systems
Hoods, capture points and collection ductwork cleaned to support COSHH and LEV examination outcomes.
Read moreDust & fume systems
Dust extraction, cyclones and fume ducting cleaned with appropriate containment and waste handling.
General factory ventilation
Supply and extract ventilation, AHUs and roof-mounted plant serving production and warehouse space.
Welding & spray booth extraction
Weld fume and paint booth extract cleaned to maintain capture and reduce fire loading.
Blockage investigation
Camera survey and targeted clearance where extraction failure is affecting production output.
How industrial programmes run
Built around production continuity, permits and safe access.
- 01
Survey & investigate
System walked, restrictions identified, deposits assessed and access constraints mapped.
- 02
Plan & permit
Method statements, risk assessments, isolations and permits agreed with your engineering team.
- 03
Access
MEWP, scaffold, rope or confined-space arrangements mobilised with access panels installed as needed.
- 04
Clean & clear
Systematic cleaning and blockage clearance with containment and controlled waste removal.
- 05
Verify & report
Condition verified, photography captured and a full report issued with maintenance recommendations.
A contractor that understands production pressure
We plan for the shift pattern, the permit system and the shutdown window — not just the ductwork.
- Urgent mobilisation for extraction failures affecting output
- Confined space, MEWP and high-level access capability in house
- Experience across food, automotive, engineering and process plants
- Containment and waste documentation for contaminated systems
- Works phased so lines keep running wherever possible
- Directly employed engineers with site inductions handled
- Consistent reporting across multi-plant portfolios
- Process extraction and general ventilation combined in one visit
Frequently asked questions
Questions from engineering managers, EHS leads and plant maintenance teams.
- Can cleaning be done without stopping production?
- Usually. Most industrial programmes are phased across lines, delivered on night shifts, or scheduled into planned shutdowns and maintenance windows. We plan isolation, permits and reinstatement with your engineering team before mobilisation.
- Do you clean LEV and process extraction as well as general ventilation?
- Yes. We clean general supply and extract ventilation, process extraction, dust and fume systems, weld extraction, spray booth ducting and LEV. Cleaning restores capture velocity and supports the employer's COSHH duties.
- What about hazardous or process-specific contamination?
- Contaminant type drives the method. We assess the material during survey, agree containment, PPE, filtration and waste routes in the method statement, and provide waste transfer documentation on completion.
- Do you work at height and in confined spaces?
- Yes. We hold MEWP, cherry picker and confined-space capability in house, which is often what determines whether high-level factory ductwork can actually be cleaned rather than just inspected.
- How quickly can you respond to a blocked extraction system?
- Where extraction failure is stopping production we mobilise as an urgent works response, usually attending within 24 to 48 hours to investigate, clear and restore the system.
