What makes an exhaust fan explosion proof?
Type A fan construction requirements specify that all materials that are in contact with the air stream be constructed of spark resistant nonferrous material such as aluminum or brass. These fans offer the highest degree of spark resistance.
What is a spark proof fan?
Spark Resistant Fans Spark Resistant Fan Construction is the technical term for industrial fans typically classified as explosion proof exhaust fans. Spark Resistant Construction is an AMCA requirement when dust, fibers, gases, vapors, or liquids could cause an explosion in the case of any kind of spark.
Are bathroom fans explosion proof?
Standard bathroom fans won’t blow up on their own, but they aren’t guaranteed to be entirely free of sparks or areas of high heat. Therefore, in places where there is a danger of contact with explosive fumes, a special sparkless exhaust fan or motor should be used.
What is explosion proof fans?
A fan or blower for a hazardous location, often called an explosion proof fan, may be required where flammable or combustible materials are in the atmosphere or being conveyed. These fans may include AMCA Type A, Type B, or Type C Spark Resistant Construction and an NFPA 70/NEC compliant explosion proof motor.
Does fan need explosion proof?
Industrial fans usually handle different types of solids and gases, some of which are flammable. As such, you want to install an explosion proof fan if you operate in a dangerous area where flammable particles or gases are in the air or passing through ventilation systems.
