Spark-Resistant Construction Options

The following AMCA Standards apply to fan applications that may involve the handling of potentially explosive or flammable particles, fumes or vapors.

AMCA Type A - All parts in contact with the airstream are constructed of nonferrous material (aluminum). Model SWB does not meet AMCA Type A spark resistant construction because the fan shaft is steel.

AMCA Type B - The fan wheel is constructed of nonferrous material (aluminum). A nonferrous (aluminum) rub ring surrounds the fan shaft where

it passes through the fan housing. Available on all SWB sizes with an aluminum wheel and rub ring.

AMCA Type C - The inlet cone is constructed of nonferrous material (aluminum). A nonferrous (aluminum) rub ring surrounds the fan shaft where it passes through the fan housing.

The constructions listed minimize the potential of ferrous components making contact with each other that may produce sparks. However, they do not guarantee against the potential of producing sparks. The installer must electrically ground all fan and system components.
