 Typical Non Ferrous Materials
  -Aluminum                         Type  C  offers  a  minimal  level  of  spark  resistance  and  only
 2  -Aluminum/Nickel/Bronze         requires  that  possible  contact  between  stationary  and  rotating
 -Monel                             components be reduced. Typically, this construction includes the
 -Copper                            use  of  an  aluminum  inlet  cone  and  an  aluminum  rub  ring.  The
 -Brass                             aluminum inlet cone will be the first point of fan wheel contact
 -Bronze                            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.
