What is the AMCA and how does it regulate axial fans?

The AMCA and Explosion Proof Fans

The Air Movement and Control Association International (AMCA) is a not-for-profit association of air system equipment manufacturers. The AMCA works to promote the air movement and control industry by providing ratings and status through the AMCA International Seal.

One way the AMCA helps the HVAC industry is by developing guidelines on the construction, selection, and use of explosion proof fans. Fans are tested by the AMCA to assure product performance (as stipulated by the manufacturer) and are then given a rating.

The AMCA is a reliable source of information concerning the HVAC industry and recommends using explosion proof fans for environments in which the following materials are handled:

  • Flammable and explosive chemicals
  • Glues
  • Paints
  • Explosive fumes
According to the AMCA, it's important that explosion proof fans be used in such environments in order to avoid the ignition of contaminants that come in contact with the metal components of a regular axial fan. The non-ferrous metals used to manufacture explosion proof fans help to contain combustion within the fan unit.

For liability reasons, most manufacturers and fan companies will not recommend fans for volatile environments. It is up to the operator or business owner to find out which type of fan is best, or hire a consultant. Look for more information from the AMCA website, or ask the professionals at about axial fans that are safe for your application.
