ABSTRACT:
A fan guard for use in connection with a textile fan blower is of minimal surface area to intrude upon the air flow or collect lint or debris. The guard has a plurality of fingers joined together by a mounting ring. The fingers are annexed in a spoke-like configuration to embrace the fan blades, and are free of additional interconnections along their length. The ends of the fingers are located so as to create an open central exhaust corridor for the fan.
