Spark Resistant Construction – Type B

Spark Resistant Construction – Type C
Type C offers a minimal level of spark resistance and only requires that possible contact between
stationary and rotating components be reduced. Typically, this construction includes the use of an
aluminum inlet cone and an aluminum rub ring. The aluminum inlet cone will be the first point of fan
wheel contact if there is a mechanical failure. The aluminum rub ring placed at the opening of the
housing where the shaft passes, protects against contact of the steel fan shaft and steel fan housing.

Split Housings - Horizontal Split Housing
Standard split along the horizontal centerline. Size 807 and above may be split by the shop for
shipping purposes.

Split Housings - Pie Split Housing
The housing is split at angles 90 degrees or greater to facilitate wheel removal without disturbing inlet
or outlet. Typical for wheel removal.
 Mohawk (newer style) - Splits between scroll and inlet housing side. Inlet side of housing does not
have a split. Not used on Double Width fans or fans with attached inlet boxes

Standard (older style) - Splits all the way down to the funnel or Inlet Plate.
