A filter assembly (10) for use with a dry bulk type trailer (B) for transporting granular material and other commodities. The trailer is pulled by a truck (T) having an air pump (P) installed thereon. The trailer has an air line (A) by which air is directed from an outlet (OL) of the pump to outlets (O1-O4) of compartments (C1-C4) of the trailer in which commodities are stored. A filter element (24) of the assembly is capable of removing dirt, dust, and rust particles entrained in the airstream flowing from the pump through the air line. The filter element is removably installed in a housing which is installable in-line withing in the airline. Couplers at each end of the housing effect connection of the housing in the air line. A pressure gauge (56) measures the pressure drop across the filter element to help determine when the element is becoming clogged and should be cleaned.
