Fume Extraction, Filtration, and Welding Control Solutions for Hire to Protect People and the Environment from Harmful Airborne Particles.

Gases, fumes and vapours are extremely hazardous to health; acute exposure could cause headaches, dizziness, sickness and breathing difficulties, while longer-term exposure could lead to cancer, lung disease or heart disease. It is therefore imperitive that dangerous particles are extracted at source and that fresh air is forced into the work area to dilute any residual airborne contaminants. RVT Group offer a wide range of fume extraction equipment that has been specifically designed to control welding fume, solvent vapours, carbon fumes & other VOCs.

It is very important due to the carcinogenic classification of welding fume, the HSE now enforces stricter control measures.

Our welding fume extraction units can be fitted with a spark guard and are capable of dealing with volatile or hot fumes.

Yes, our welding fume filter kits are designed for hard-to-reach or confined areas. We also offer ventilation equipment to force clean air into the workspace to dilute any residual fume.

We offer a variety of RAVEX® extractors, including:

RAVEX® Portable Welding Fume Filtration Unit is lightweight and ideal for use in confined work spaces or hard-to-reach areas.

RAVEX® Mobile Welding Fume Station is on castor wheels so it can be positioned next to a work bench to create a welding fume station or moved around a work area as a project progresses. It has a convenient extraction arm to capture fumes directly at source.

How effective are RVT’s welding fume filters?

Both RAVEX® Portable Welding Fume Filtration Unit  and RAVEX® Mobile Welding Fume Station have 99.9% filtration efficiency

RVT Group uses our own devised 3C’s® methodology:

3C’s® the fume using extraction arms or hoods

Contain and filter the fume hazard

Control the work area by providing ventilation to dilute residual contaminants.

Carcinogenic substances are defined as either causing cancer or helping cancer to grow.

In 2019, welding fume was reclassified as carcinogenic because new scientific evidence from the International Agency for Research on Cancer found that exposure to mild steel welding fume can cause lung cancer and possibly kidney cancer in humans. As such, new welding fume guidance was issued. This has highlighted the importance of using hazard control systems for filtering and extracting fumes from welding, soldering and more.

If you're unsure what type of fume extraction would work best for your current project, our team of consultants can help navigate the complex nature of welding fume extraction and provide options for industrial, large-scale extraction units with flexible exhaust arms.

Yes, welding fumes are classified as carcinogenic and exposure can increase the risk of lung cancer and other serious health issues.

Yes, for example the RAVEX® Wandafilta Plus - Extraction & Filtration Kit is designed for use in confined work areas because it can generate negative pressure, and has up to 3 stages of filtration EU4, EU7 or HEPA + carbon, and is powerful enough to maintain airflow over long duct runs.

Our solutions incorporate a centrifugal fan, which is safe for hot or flammable fume extraction, because the airflow doesn’t pass over the motor. We also recommend fitting a spark arrestor if flammable or spark-producing fumes are present.

Yes, our RAVEX® D2 fume extractor has dual arms and includes a HEPA filter for particulates, plus the option of a carbon filter to capture gases and odours.

Our RAVEX® D1200 unit supports up to 8 extraction ports, allowing multiple hoses and points of capture.

Yes, for example, the RAVEX® Wandafilta Plus - Extraction & Filtration Kit which can be easily moved around as work progresses, and offers 3 stages of filter media, up to HEPA filtration.

Our RAVEX® range is designed to control a wide variety of fumes including; solvent or paint vapours, hot or volatile mists, gases, VOCs, and chemicals.

A carbon air filter or an activated charcoal air filter consists of treated charcoal. These will remove airborne contamination through the process of adsorption, whereby molecules chemically react to the treated charcoal. They are often used to remove gases and Volatile Organic Compounds (VOC’s).

Yes, metal-bladed centrifugal fans are suitable for extracting heat and sparks. A Spark arrestor should be fitted to the intake of the extraction system if there is the danger of these being drawn in.

Yes, however the type of machinery you can use will depend on the scenario. If the fan needs to be situated within an ATEX-rated area, the extraction unit must carry the relevant class of certification. However, if the unit will not be situated in an ATEX zone area, you could use a non-Atex rated centrifugal fan. Centrifugal fans are safe to use with volatile fumes, because the motor sits outside of the airflow.

WELs stands for Workplace Exposure Limits. There are 500 substances individually listed within EH40 with a workplace exposure limit, therefore we would strongly recommend that you download a free copy of this document from the HSE website. Employers must implement adequate controls, such as local exhaust ventilation (LEV) systems, to ensure that exposure limits are not breached.

The concentration of toxins and duration of exposure can be the difference between feeling a little dizzy or dying within a few minutes, which is why it is so important to ensure that you have adequate ventilation and/ or extraction in place. Even if the concentration is low, excessive exposure over several years can lead to the development of life threatening illnesses and diseases, such as cancer.

Harmful fumes, gases and vapours are generated by a variety of activities on site, for example; welding, spraying, painting and the use of VOCs.

Yes, our LEV consultants are experts in hazard control and can help assess your site requirements, propose the right extraction hood, fan, filter, and duct configuration, to provide a fully compliant solution.

Yes, we have high-pressure fans that can be used as part of the LEV system, that sit outside the work area and operate with narrow and long lengths of ducting runs, making them suitable for confined work areas that are based a long way from the atmosphere.

Yes — for example, for dust we have DUSTEX® DustMaster® Pro and for fumes we have RAVEX® Wandafilta Plus - Extraction & Filtration Kit.

Yes, we offer temporary hire of LEV solutions, which makes them ideal for shutdowns, maintenance, welding, or cutting tasks. Our team will help design and set up the system for your specific project needs.

Particulate filters - Designed to trap heavy particulates such as particles created from cement dust and wood cutting. A medium grade filter like this is also 80% effective at removing smaller particulate matter down to 1 micron in size (PM1 - 1 μm) including some finer dust particles, industrial fumes, and bacteria spores.
Fine filters - Ideal for visible dust removal and designed mainly for low-toxicity dusts or where the system is venting to a safe area. Acts as a protective layer when using highly efficient filters up to HEPA standard.
High Efficiency Particulate Air (HEPA) - The most efficient filter available on the market, designed to give virtually clean air. Welding fume, burning fume, smoke and even airborne bacteria such as COVID can be caught with a filter of this efficiency.
Gas filters - A particulate filter will not prevent gas from passing through it. Work that requires gas to be captured needs a filter with specific materials such as activated carbon. When gas passes across these filters, a chemical reaction causes the gas molecules to stick to the surface of the filter.

Our standard LEV setup includes a capture hood, ducting, a fan, a filter, and a discharge point.

Our LEV systems are designed to extract a variety of hazardous airborne contaminants including welding fumes, solvent vapours, gases, mists, and fine or heavy dust.

We provide a full suite of LEV solutions for fume, dust, mist, gas, and vapour extraction. Our range includes portable fume extractors, duct‑mounted filtration units, and large multi‑spigot LEV systems, tailored to the needs of construction, industrial maintenance, and confined‑space work.

Yes, we can supply an LEV kit which will come with a TExT certificate. The certificate demonstrates that the kit was supplied in good operational condition, but it is the customers responsibility to check that the system is properly installed and working as intended.

Yes, our Local Exhaust Ventilation (LEV) systems undergo Thorough Examination and Testing before leaving our warehouse, so you can rest assured that it’s compliant and in peak working condition when it reaches you. Our LEV testing is carried out by qualified LEV engineers who hold BOHS (British Occupational Hygiene Society) certifications (e.g. P600, P601, P604).
