Spark Resistant Fans
Spark Resistant Fans for Performance and Compliance
When combustible dust or gas is present in the process environment, an AMCA spark resistant fan will be well suited for the job. The construction of our line of spark resistant fans reduces the chances that a spark caused by fan component friction will ignite hazardous or combustible gases when fans are used in close proximity to combustible materials or a flame.

When developing an explosion proof system, careful consideration of all system components is needed to ensure the safe handling of such gas streams. Air Systems is highly experienced in spark resistant applications. Our team takes the time to understand your process, challenges, and goals to develop a custom spark resistant fan solution that meets your specific needs.

QUESTION: I need an explosion proof fan. Do you carry them?
ANSWER: We offer spark resistant fans as classified by AMCA. Technically there is no such thing as an explosion proof fan – spark resistance is the standard.
Spark Resistant Construction AMCA Standards define three types of spark resistant construction:
Type A — All parts of the fan in contact with the airstream must be made of non-ferrous material.
Type B — The fan shall have a non-ferrous impeller and non-ferrous ring about the opening through which the shaft passes. Ferrous hubs, shafts, and hardware are allowed if construction is such that a shift of impeller or shaft will not permit two ferrous parts of the fan to rub or strike.
Type C — The fan must be so constructed that a shift of the wheel will not permit two ferrous parts of the fan to rub or strike.
