Various types of the Explosion-Proof Fan are available at the Intrinsically Safe Store, depending on your needs.
Explosion-Proof fans or hazardous location fans and blowers are an essential part of a warehouse, plant, mill, spray booth, tank, confined space. Additionally, fans are crucial in any other area where ignitable fumes, gases, or dust may be present.
Fine powder such as flour or coal is combustible because many highly volatile gaseous compounds such as methane, ethylene oxide, coal gas, and many other transported materials. Should combustion occur within the fan, it will withstand the explosion without rupture or transmitting ignition to the atmosphere.
But first, let’s answer the most important question:
What does Explosion-Proof mean?
The term Explosion-Proof refers to products that are capable of containing an explosion. However, it doesn’t indicate that the product can withstand internal explosions without allowing flames or hot gases to escape and initiate an explosion in the surrounding atmosphere. The term Explosion-Proof deems that products are certified by competent authorities after passing prescribed testing and research.
An electrical product that is marked Explosion-Proof signifies that the product has an apparatus enclosed in a case. Additionally, the protective case is resistant to the explosion of a specific gas or vapor potentially circulating within it. The equipment prevents the ignition of the surrounding atmosphere by sparks, flashes, or explosions occurring within. And, it operates at a low external temperature, preventing the surrounding atmosphere from igniting. Explosion-Proof fans abide by the National Fire Protection Association (NFPA) the USA, under Standard No. 70, Article 100, of the National Electric Code.
For enclosures to obtain an Explosion-Proof rating, the equipment should contain any explosion originating within its housing. As well as prevent sparks within its housing from igniting vapors, gases, dust, or fibers in the air surrounding it.
