Electric motors are susceptible to over-heating when running on over-load, when their supply or self-cooling air is reduced, when ambient temperature is too high or when any part of the motor surface is thermally insulated by its installed situation. Any one of these conditions could lead to an explosion. ATEX is an acronym derived from the words “Atmospheres Explosibles” that is soon to be superseded by the term UKCA EX or UKEX in the UK, and forms part of a European equipment directive known as ATEX 2014/34/EU. ATEX 2014/34/EU was adopted within the UK Statutory guidance following Brexit, titled: All speed controllable ATEX motors receive less cooling air on speed reduction and must therefore be supplied with thermistor over-temperature sensors to protect against shell temperature in excess of the motor temperature class.

All the standards that were on the EU Commission list of Harmonised Standards for ATEX were transposed and became Designated Standards for the UK legislation. Use of such a standard gives a presumption of conformity with the Directive/Statutory Instrument for those requirements covered by the standards. The Designated Standards list continues to refer to standards by their EN number, rather than their BS number. The coverage of each standard, in respect of the directive/SI requirements, is given in a specific European Annex to the standard. Our fume extraction fans have proven their durability and reliability in the laboratory fume cupboard market and educational settings for over 30 years. Our team of fan integration experts have worked with schools, colleges and universities to select and specify the correct corrosion resistant fan to suit their fume extraction system requirements whilst ensuring competitive pricing and lead times. It is strictly the responsibility of the end user to perform a DESEAR risk assessment to ensure that flameproof zones are properly defined in terms recognised by ATEX legislation It is recommended in ATEX 2014/4/EU and the prior legislation, 99/92/EC, that an Explosion Protection Document be produced, which will help to define the ATEX code for any equipment to be installed in the flameproof zone. In the UK other relevant reports may also have been filed under Health & Safety or COSHH regulations which may assist in the process. ATEX Explosion Proof Fans Coding

This is an amazing service we do for thousands of businesses throughout the UK and Ireland every year. We work with such a wide variety of industries, from manufacturing, industrial, woodworking, pharmaceutical and automotive workshops to schools, colleges and military establishments. We offer a wide range of chemical resistant fume extraction fans, (also commonly known as plastic or polypropylene fans) which are ideal for extracting chemical fumes. Polypropylene plastic fans for though work environments in Laboratories, the chemical and pharmaceutical industries. Equipment and protective systems intended for us in potentially explosive atmospheres regulation 2016. Fume Cupboard efficiency can be increased with the integration of EC polypropylene fans for maximum efficiency. Our EC range of corrosion resistant fans can reduce fan energy consumption by up to 20% without affecting performance. Due to the chemical composition of the substances used in schools and universities, the fume cupboard extract fans need to be able to handle the corrosive air without risk to the operation. Axair offers specifically designed polypropylene fans for this type of application as the material properties allow the fan to operate in the corrosive air stream. Learn more about reducing fan energy consumption in fume cupboards here. There is always a risk of accidents happening where there is a large variety of chemicals stored or where there are ongoing operations producing vapours and corrosive gases. Fume cupboards prevent potentially dangerous vapours being released into the classroom in two main ways; through ducting or through filtered, recirculated air. Ducted fume cupboards draw air through the sash opening over the working area and through ducting to the outside of the building, most often the roof. This method is widely used as it suitable for extracting more toxic vapours than recirculating filtered fume cupboards. The latter is more suited to experiments using much less hazardous substances. Additionally, school fume cupboards act as a physical barrier between reactions and the classroom or laboratory. This provides a degree of protection against inhalation exposure, chemical spills and fires.

equipment intended for use in domestic and non-commercial environments where potentially explosive atmospheres may only rarely be created, solely as a result of an accidental leakage of fuel gas. To be fitted at the lowest point of the fan scroll to allow water to run away. Thread size 3/8″ BSP, hose connection 12mm Ø. Fan housing predrilled and tapped to hose connector. Chemical resistant fume extraction fans are to be used in conjunction with several products, from our fume extraction, dust extraction or vehicle exhaust extraction range. At-source capture hoods will capture the contaminants in the LEV system and draw them towards the centrifugal fan, and depending on the working process will expel particulates via a filtration unit, or directly to the atmosphere via a high-velocity cowl, as per HSG258: Controlling Airborne Contaminants at Work: A Guide to Local Exhaust Ventilation (LEV).Air flow controllers can be incorporated to monitor and control air speed and show the correct functioning of the fume cupboard’s air flow. Different versions are available depending on your requirements. The required EU CE Marking is supported by ATEX documentation; UKCA marking is supported by UKEX documentation. The UKEX Certificate number and UKCA marking can be applied either additionally to the ATEX marking, or as an alternative. Most manufacturers seem to have elected to show both sets of marking at the same time. The relevant number of the Notified Body and Approved Body, responsible for supervision of manufacture, must be marked adjacent to the CE and UKCA marking. For components, where the CE and UKCA marking are not applied, both numbers should still be shown, if relevant. During school science experiments and demonstrations, it is commonplace to use fume cupboards. Fume cupboards capture and remove any harmful substances generated and reduce the exposure to a safe level. These include harmful gases, vapours, aerosols and particulates. Older students sitting exams may be required to complete certain hazardous studies to understand how chemical reactions work, this may involve the production of substances such as sulphur or hydrogen, so it is imperative that all health and safety regulations are met. Choosing the correct fume extraction fans for school fume cupboards is crucial for reducing the user’s exposure to hazardous substances during the experiments and demonstrations as the educational setting has a duty of care to protect every student from harm. School and university fume cupboards act as a physical barrier between reactions and the classroom or laboratory. This provides a degree of protection against inhalation exposure, chemical spills and fires.

Fume cabinets are ideal for situations where maximum efficiency is necessary when extracting harmful fumes. The cabinets are designed to allow operators to see through the cabinet while working, yet protecting them at all times by safely controlling exposure. The fume extract fan will collect and dispose of fumes before they become airborne. Certain environments, such as laboratories, may require fans that can withstand corrosive fumes or explosive gasses.Everyone is familiar with the stylised Ex within a hexagon. This symbol is given in the standards that support both ATEX and UKEX, so does not change. The single coding on a label (familiar from ATEX) applies equally to ATEX and UKEX equipment. The weather pedestal offers a more enclosed casing for outdoor installations, it totally covers the fan motor beyond the IP55 protection. All the UK bodies that were previously EU Notified Bodies became UK Approved Bodies. UKEX Certification SEAT fume cupboard extract fans are particularly popular in educational facilities, not only because of their resistance to chemical impairment, but also due to their minimal noise emissions, simple control & monitoring, and their easy installation.
