Why Every Workshop Needs a Reliable LEV System (And How Ventxlabs Gets It Right) 

If you run a workshop, factory floor, or any space where dust, fumes, or airborne particles are part of the job, you've probably heard the term "LEV system" thrown around by health and safety officers. But what does it actually mean, and why should your business care about it?

Let's break it down in plain terms.

What Is an LEV System? 

LEV stands for Local Exhaust Ventilation. In simple words, it's a system designed to capture dust, fumes, vapours, or mist right at the point where they're produced, before they have a chance to spread into the air your workers breathe. Instead of relying on general ventilation (opening windows or running a big fan), an LEV system targets the problem at its source. 

Think of it like a kitchen extractor hood, but built for industrial environments. Whether it's wood dust from a carpentry workshop, chemical vapours from a spray booth, or metal particles from a grinding station, an LEV system pulls the contaminated air away and filters it before releasing clean air back into the environment. 

Under UK health and safety law (COSHH regulations), employers have a legal duty to control exposure to hazardous substances. A properly installed and maintained LEV system isn't just good practice, it's often a legal requirement. And beyond compliance, it protects the long-term health of your team, reduces sick days, and keeps your workplace running smoothly. 

Why LEV Systems Matter More Than People Think

A lot of business owners assume that if their workshop "looks clean," the air must be fine too. Unfortunately, that's rarely true. Many airborne contaminants are invisible to the naked eye but still harmful when inhaled over time. Conditions like occupational asthma, lung damage, and other respiratory issues often develop slowly, which is exactly why prevention matters so much. 

A well-designed LEV system does three things really well: 

1. Captures contaminants close to the source

2. Filters and cleans the extracted air

3. Releases (or safely disposes of) the filtered air

At Ventxlabs Ltd, we work with businesses across the UK to design, install, and maintain LEV systems that are tailored to their specific industry and risks. No two workshops are the same, so we don't believe in one-size-fits-all solutions.

Welding Extract Systems: A Closer Look 

One area where LEV systems play an especially important role is welding. Welding extract systems deserve their own mention because welding fumes are among the most hazardous airborne contaminants found in industrial settings. 

When metal is welded, it produces a mix of fine particles and gases, some of which are now classified as carcinogenic. This means even short-term exposure without proper extraction can pose real health risks to welders and anyone working nearby.

A dedicated welding extract system is built specifically to capture fumes right at the welding torch or nearby the work area, often using flexible extraction arms, downdraft benches, or fume extraction units positioned close to the source. Unlike general LEV setups, welding extraction needs to handle high-temperature particles and fast-moving fume plumes, so the equipment has to be tougher and more responsive.

At Ventxlabs, our welding extract systems are designed with this in mind. We assess your welding processes, the layout of your workspace, and the type of welding you carry out (MIG, TIG, stick welding, etc.) to recommend the most effective extraction setup, one that keeps your team safe without slowing down production.

Choosing the Right LEV Partner

Not all LEV installations are created equal. A poorly designed system might look fine on paper but fail to actually capture contaminants where they're produced. That's why working with a specialist matters. 

Ventxlabs Ltd has built a reputation for delivering LEV and extraction solutions that are practical, compliant, and genuinely effective, not just installed and forgotten. We also offer testing, maintenance, and LEV examination services (required at least every 14 months under COSHH) to make sure your system keeps performing the way it should. 

If you're unsure whether your current setup meets the mark, or you're starting from scratch, our team is happy to talk through your options.  

Frequently Asked Questions

1. What does LEV stand for in health and safety?

LEV stands for Local Exhaust Ventilation, a system used to capture and remove hazardous fumes, dust, or vapours at the point where they're generated. 

2. How often does an LEV system need to be tested?

Under COSHH regulations, most LEV systems require a thorough examination and test at least once every 14 months, though some high-risk processes need more frequent checks. 

3. Do small workshops need an LEV system?

Yes, if your workshop produces dust, fumes, or vapours that could harm workers, an LEV system is usually required regardless of business size. 

4. What's the difference between general ventilation and an LEV system?  

General ventilation simply moves air around a room, while an LEV system captures contaminants directly at the source before they spread into the wider workspace. 

5. Why is welding extraction treated differently from other LEV systems?

Welding fumes contain fine particles and gases that can be harmful even in small amounts, so welding extract systems are built to respond quickly and handle high-temperature fume plumes close to the source.
