Suitable for a wide range of potentially explosive environments, our range of award winning ATEX Centrifugal fans features over 38 ranges of explosion proof fans. The correct ATEX centrifugal fan will reduce the risk of an explosion occurring from potentially dangerous gases and dusts by ensuring the construction material, permissible pairings, motor protection rating, hazardous area zone and temperature rating are suitable in preventing an explosion. Our expert team are certified to supply ATEX fans and their necessary components in line with the relevant ATEX Directive 2014/34/EU as implemented into UK legislation following Brexit.
Please note that we cannot supply an ATEX fan without first recognising that you, or a third party, have undertaken a thorough risk assessment to determine the ATEX rating of the equipment you require. This is in line with ATEX Directives instructions that places an emphasis on the end user being responsible for their ATEX assessment. There are many independent consultants who can carry out your survey to ensure you receive the safest and most effective industrial ATEX fan for your applications ATEX gas and dust zone.
ATEX fans can be manufactured from semi conducting polypropylene, fabricated steel with copper or aluminium non-sparking components, cast aluminium or in stainless steel.

99/92/EC ATEX 137 (formerly 118a) is an EC directive often referred to as “The Users Directive” and is concerned with safe working conditions. It is implemented into UK law through regulations 7 & 11 of the Dangerous substances and Explosive Atmospheres regulation 2002 or DSEAR.
ATEX 137 requires the end user to define what equipment manufacturer can lawfully supply
ATEX Directive 2014/34/EU (Previously 94/9/EC) is often referred to as “The Equipment Directive” is concerned with ATEX product compliance, The legislation enables the equipment manufacturer to supply product that meets or exceed the minimum requirements of the end users DSEAR risk assessment. It is implemented into UK under the equipment for potentially explosive atmospheres regulations 2016.
ATEX 114 requires the equipment manufacturer to supply safe and lawfully suitable products
In line with the above, manufacturers will generally select the type of motor required to meet the regulations but clients may choose to over specify the motor for added security. Our industrial team of fan integration specialists can help to select the correct fan for your application.
Ex eb equipment is designed and manufactured with components that prevent ignition sources being generated internally such as static discharges or high temperatures and is suitable for Zone 1 areas. Ex eb provides an impact resistant enclosure to ensure its contents never produce sparks, temperatures or current creepage that could ignite the flammable atmosphere which may enter the enclosure. Therefore, Ex eb rated enclosures are explosion protected but not flameproof.
Ex ec equipment is constructed and certified as “Explosion Protected” according to the “Increased Safety” standard but to a lower level than eb. Ex ec is suitable for Zone 2 non-sparking (formerly nA) hazardous areas.
If an explosive atmosphere of flammable substances is specified, the following zones may exist. You are advised to use an independent consultant to determine the zone protection you require. Learn more about ATEX Gas & Dust Zones here.
Category 2 – Zone 1 Gas – Zone 21 Dust – Present Intermittently where an explosive mixture may be present occasionally in normal operation.
Category 3 – Zone 2 Gas – Zone 22 Dust – Present Abnormally where an explosive mixture is not expected to be present in normal operation or will only be present for a short amount of time.
Please note we supply zone 1 & 2 gas, and zone 22 dust with two temperature ratings.

Hazardous area equipment is classified according to the maximum surface temperature produced under the maximum operating capacity at an ambient temperature of 45°C, or as otherwise specified. The standard classifications are below and highlight the lowest temperature which a gas, vapour or dust will be ignited. For example, if a potentially hazardous explosive gas is hydrogen, then all equipment used must meet the T1 rating, meaning that all equipment used must not be able to create a surface temperature of greater than 450°C. Anything that can generate a hotter surface temp of greater than 450°C must not be used as this will increase the likelihood of an explosion by igniting the hydrogen in the atmosphere. Please advise the temperature class when enquiring about an ATEX centrifugal fan to ensure we can select a product accurately.
T1 450°C
T2 300°C
T3 200°C
T4 135°C
T5 100°C
T6 85°C
Temperature classes for ATEX dust fans are absolute and therefore should not be referred to in the above classifications.
Most of our ATEX certified centrifugal fans are suitable for ventilation in environments classified as ATEX.
We advise that you always speak to an independent consultant who will conduct a survey to determine accurate gas and dust zones, temperature classes and the ATEX rating required to ensure safe and efficient operation of your fan.

Landfill gas is a natural by-product produced by the microbial degradation of biodegradable organic material present within the landfill. The degradation process takes place in five stages as described later. The transition from one stage to the next being dependent upon many characteristics and therefore the time for which each stage is present is difficult […]
Outside of major users such as chemical, petrochemical and similar process industries enquiries for flameproof fans tend to come from specifiers, resellers and end-users, many of whom have no previous experience in the field and may not even be aware of ATEX Directives. What does ATEX Mean? ATEX, for the uninitiated, is an acronym […]
The specification and purchase of ATEX fans is difficult enough given the need to understand and meet the various directives and regulations governing their special application. Once having found an ATEX fan that satisfies a particular risk assessment there is the added problem of trying to find a sufficient choice of fan to meet other […]
