Frequently Asked Questions
LEV Testing & Compliance
How often should LEV systems be tested?
LEV systems should be tested at least every 14 months according to HSE guidelines. However, some industries may require more frequent testing depending on the substances being extracted.
What happens if my LEV system fails testing?
If your system fails testing, we'll provide a detailed report outlining the issues and recommend necessary repairs or modifications to bring it back into compliance.
Do I need LEV testing for all extraction systems?
Yes, any Local Exhaust Ventilation system that extracts hazardous substances must be tested and maintained according to COSHH regulations.
System Design & Installation
How long does installation take?
Installation time varies depending on system complexity. Simple systems can be installed in 1-2 days, while complex multi-point systems may take 1-2 weeks.
Do you provide site surveys?
Yes, we provide free site surveys to assess your requirements and design the most appropriate solution for your specific needs.
Can existing systems be modified?
In most cases, yes. We can often modify existing systems to improve performance or add new extraction points rather than replacing the entire system.
Maintenance & Service
How often should filters be changed?
Filter replacement frequency depends on usage and the type of particles being extracted. We'll recommend a maintenance schedule based on your specific application.
What maintenance is included in your service contracts?
Our service contracts include regular inspections, filter changes, system cleaning, performance testing, and minor repairs to keep your system running efficiently.
Do you offer emergency repairs?
Yes, we provide emergency repair services for critical extraction systems to minimize downtime and maintain workplace safety.
