The 270SF filter will mount by means of a pipe flange to a mating flange on the stack. The size of the flange can be specified by the user and can include 2”, 3”, 4”, 6” or DIN type. A 1/2” NPT female threaded connection is provided for the sample probe to mount inside the mounting flange.
After securing the heated sample line, use a heat gun to shrink the entry boot onto the sample line. The goal is to keep the temperature of the gas sample at a temperature above the dew point of the gas all the way from the stack to the sample cooler/dehydrator.
