LEV Remedial Works & Repairs

Failed Your LEV Test? System Broken Down? We Can Help.

When your LEV system fails its statutory test or breaks down unexpectedly, you need expert diagnosis and rapid remedial action. Combined Air Limited provides comprehensive remedial works and emergency repairs to restore system performance and bring you back into compliance. Our BOHS qualified engineers (P601, P602, P603, P604, W201) don't just fix symptoms - we identify root causes and provide lasting solutions.

Why LEV Systems Fail

Understanding why systems fail is the first step to effective remediation:

Design Problems
Some systems were never adequate from installation. Common design flaws include insufficient airflow, poorly positioned hoods, excessive duct lengths, or incorrect fan specifications. No amount of maintenance can fix fundamental design issues.

Wear and Deterioration
Even well-designed systems degrade over time. Ductwork corrodes, joints loosen, fan impellers wear, and filters clog beyond cleaning. Regular servicing prevents many failures, but eventually components need replacement.

Process Changes
Your system may have been adequate when installed, but changes to processes, new equipment, or increased production can render it ineffective. The LEV system hasn't failed - your requirements have changed.

Poor Maintenance
Neglected systems gradually lose performance. Blocked filters, damaged hoods, worn belts, and accumulated deposits all reduce effectiveness until the system fails its test.

Damage
Forklift impacts, dropped materials, accidental modifications, or production changes can damage ductwork, hoods, or equipment, compromising system integrity.

Our P602 design qualification enables us to distinguish between these causes, ensuring you invest in the right solution.

Types of Remedial Work We Provide

Failed Test Rectification
Addressing specific deficiencies identified in your thorough examination and test (TExT) report. We correct inadequate velocities, repair damaged components, and restore system performance to meet HSG258 standards.

System Performance Restoration
When your system no longer provides adequate worker protection, we diagnose why and implement solutions. This may involve cleaning, repairs, component replacement, or system modifications.

Design Problem Identification & Correction

Using our P602 design knowledge, we identify when poor performance stems from fundamental design limitations rather than maintenance issues. We work with top industry design consultants to implement design improvements, from minor modifications to complete system redesign.

Emergency Breakdown Repairs
When your system stops working entirely, we provide urgent response to restore operation. We carry common spares and can implement temporary solutions while permanent repairs are arranged.

Hood Replacements & Modifications
Damaged, corroded, or inadequate hoods can be repaired, modified, or replaced. We ensure new hoods meet HSG258 design principles and provide effective capture.

Ductwork Repairs & Modifications
We repair damaged ductwork, seal leaking joints, replace corroded sections, and modify systems to accommodate process changes or new equipment.

Fan & Motor Replacement
When fans or motors fail beyond economical repair, we specify and install appropriate replacements, ensuring correct specifications for your system requirements.

Filter Housing Modifications
Improving filter access, increasing filter capacity, or upgrading filter technology can significantly improve system performance and maintenance efficiency.

System Extensions

Adding extraction points for new processes or equipment, extending ductwork to new areas, or increasing system capacity to accommodate business growth? We work with industry leading design consulatnts to ensure any improvments or additonal processes are correctly accounted for to ensure the system is capable and is still compliant.

Emergency Breakdown Service

System Down? We Understand the Urgency

When your LEV system fails completely, production may stop and workers are unprotected from hazardous contaminants. We offer:

Rapid Response - Emergency callouts prioritized
Fault Diagnosis - Quick identification of problems
Temporary Solutions - Get you operational while permanent repairs arranged
Spare Parts Access - Common components available
Out of Hours Support - Contact us for urgent failures

A non-operational LEV system means workers are unprotected. We respond quickly to restore protection.

Design Problems vs. Maintenance Problems - Our P602 Advantage

Many remedial contractors can't distinguish between these - we can.

Maintenance Problem Example:
System fails due to blocked filters, worn belts, or damaged ductwork. Solution: Clean, repair, or replace the affected components. Cost: Moderate.

Design Problem Example:
System fails because the hood was incorrectly positioned, fan was undersized, or ductwork has too much resistance. Solution: System modification or redesign required. Cost: Significant.

Why This Matters:
If you have a design problem but only do maintenance repairs, you'll pass money trying to fix an unfixable system. If you have a maintenance problem but get told you need redesign, you'll waste money on unnecessary work.

Our P602 qualified engineers identify which problem you have, ensuring you invest in the right solution and don't waste money on ineffective remedial works.

The Compliance Clock is Ticking

A failed LEV test means you are not COSHH compliant.

Under COSHH Regulation 9, your LEV system must be "maintained in an efficient state, in efficient working order, and in good repair." A failed test is evidence you're not meeting this requirement.

Implications:

• HSE enforcement action possible
• Workers are not adequately protected
• Insurance implications
• Duty of care compromised
• Further testing cannot be delayed indefinitely

Rectification should be completed promptly. The longer you operate with an inadequate system, the greater the risk to your workforce and your legal position. We understand the urgency and work quickly to restore compliance.

Our Remedial Process

1. Assessment
We review your failed test report, visit site if needed, and conduct our own evaluation using BOHS-qualified expertise to identify root causes.

2. Root Cause Analysis
Using P602 design knowledge and P604 performance evaluation skills, we determine whether issues stem from maintenance, design, or both.

3. Proposal
We provide a detailed quotation outlining:

• Problems identified
• Recommended solutions
• Timescales for completion
• Costs
• Expected outcomes

4. Implementation
Our engineers carry out agreed remedial works with minimal disruption to your operations. We provide progress updates and notify you of any additional issues discovered.

5. Post-Repair Testing

After completing remedial works, we conduct performance testing to verify the system now meets HSG258 standards and provides adequate worker protection.

6. Retest Arrangement
If your original test failure requires formal retesting, we can arrange this or liaise with your existing test provider.

Common Repairs We Perform

Hood Repairs:

• Replacement of damaged or corroded capture hoods
• Repositioning hoods for better capture
• Adding flanges or side baffles to improve effectiveness

Ductwork Repairs:

• Sealing leaking joints
• Replacing corroded sections
• Straightening damaged ductwork
• Adding inspection/cleaning access points

Fan Issues:

• Bearing replacement
• Impeller balancing or replacement
• Motor replacement
• Drive belt renewal

Filter Problems:

• Filter replacement or cleaning
• Filter housing repairs
• Upgrading to higher efficiency filters
• Improving filter access

System Modifications:

• Adding extraction points
• Increasing system capacity
• Installing new fans or motors
• Ductwork rerouting

When is Redesign Necessary?

Sometimes remedial repairs aren't enough - the system needs fundamental redesign:

Indicators Redesign May Be Needed:

• System has repeatedly failed tests despite repairs
• Original design was inadequate
• Process has changed significantly since installation
• Ductwork runs are excessively long
• Fan is at maximum capacity but still inadequate
• Hood positioning is fundamentally wrong

We provide honest advice: If your system needs redesign, we'll tell you. If repairs will solve the problem, we won't recommend unnecessary redesign. Our P602 qualification enables this distinction.
