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.
