Generally speaking, using a material handling fan to convey continuous trim may not be your best option. Continuous trim is just that - one long continuous piece. When using the suction generated by a material handling fan to convey that long continuous piece, the trim must pass through the rotating blades of the blower or fan. This means that the blower or fan blades literally have to tear the trim into pieces in order to make it through the fan. Using the material handling fan or blower to tear your trim into pieces will generate lots of dust and cause harm to the fan or blower over time (blowers and fans are not designed to tear solid materials).
A better option may be to use a venturi based system. Venturi systems use the pressure side of a blower and it's the venturi that generates the suction. The trim has a straight path through the venturi so it does not need to be broken up into pieces. However, if your application requires the trim be chopped, trim choppers (designed specifically to chop continuous trim) with rotating blades and bed knives can be utilized after the venturi.
