Fume Extraction Systems



Fume extraction systems are specialist local exhaust ventilation (L.E.V.) systems provided to capture, convey and disperse / filter airborne fumes and vapors in the workplace.

The reason for fume extraction?


In today's workplace there are numerous hazards that have the potential to cause harm to unsuspecting employees. 


Fume extraction (L.E.V.) systems therefore require careful individual consideration of the process and the contaminant to be controlled.


Thousands of people die from work-related lung diseases every year, in many cases due to exposures that took place many years before. Breathing in certain dusts, gases, fumes and vapors in the workplace can cause serious, long-term lung damage. Diseases like, asbestosis, silicosis, chronic obstructive pulmonary disease (COPD), asthma, emphysema and even lung cancer, all cause severe, often incurable, health problems that can ruin lives.

Legal Requirements -


The Health and Safety at Work act, Control of Substances Hazardous to Health Regulations (C.O.S.H.H.) and the Management of Health and Safety at Work Regulations all place a legal requirement on owners of LEV systems to ensure that they are controlling the operator’s exposure to harmful substances.


A Thorough Examination and Test forms part of this legislative requirement where HSG 258 “Controlling airborne contaminants at work” provides guidance on the minimum requirements.


The content of the L.E.V. Thorough Examination and Test is individual to each system installation and the frequency of the test is dependent on the process and can vary from 1 month to a maximum of 14 months intervals. All records must be kept for a period of 5 years.
