The Need for Fume Extraction

Local and international health and safety legislation (such as COSHH, NIOSHH and OSHA etc) states that it is the employers responsibility to protect the health, welfare and safety of their employees. Failure to do so can result in expensive legal action, potential fines and poor employee relations.

Many types of fumes, vapours, odours and particulates are hazardous to health if inhaled. People can become permanently sensitised to fumes which means that continued exposure, even to very small amounts of fume, may cause asthma attacks or other respiratory diseases.

To prevent the risk of hazardous substance exposure, fume extraction systems must be installed. The two most common forms of fume extraction consist of;

External – pump contaminated air into the environment outside the building

Internal – at source capture and recirculation filtering to return clean air back into the local environment

A high performance fume extraction system will help to;

  • Protect employee health
  • Ensure compliance with Health & Safety regulations
  • Increase production speeds
  • Reduce complaints by operators due to odours, dust and vapours
  • Avoid possible cost of health compensation claims
  • Reduce product contamination
  • Provide a better working environment
  • Reduce downtime

How BenchVent Recirculation Cabinets Remove Potentially Harmful Containments

Our ductless fume cabinets incorporate a powerful fan system, which pulls the contaminated air from within the hood away from the operator’s breathing zone. During operation this ensures that any fumes, vapours, odours and particulates associated with the operator’s activity are forced up into the filter system. Here, various filter media are used (depending on what activities the unit is required for) to efficiently extract and clean the air, so that it can be safely returned into the local environment.

Filter Roles

What filter specification your air filtration cabinet utilises is dependent on the activities conducted within it. Some of the most common filter types include;

Pre-Filter – A typical pre-filter will capture the larger particles contained within the polluted air

HEPA Filter – High-efficiency particulate arrestance (HEPA) offers 99.97% filter efficiency on particles down to 0.3 microns in size.

Activated Carbon Filter  This filter is used for the extraction of odours, gases and fumes.
