The present invention provides a mobile filter cleaning system allowing movement to a site where dirty filters are located. The filter cleaning system includes a trailer or truck, an air compressor, an aftercooler, an air drier, a filter cleaning station, a compressed air tank, a dust collector, a fan and fan motor, and an airflow verification unit. Along a first fluid communication, compressed air is used to clean dirty filters in the cleaning station and filter cartridges in the dust collector. Along a second fluid communication dirt, liberated from the dirty filter is pulled from the cleaning station to the dust collector by a fan-induced draft. The compressor creates the first fluid communication and the fan creates a second fluid communication.

The connector of claim 1 further including a step extending above an upper bearing surface of said central bridge and along said side walls to define an upper horizontal seat and a lower horizontal seat, wherein said rail includes an upper face and a lower face, wherein said tail space is between said upper face of said rail and said lower surface of said central bridge, and wherein said side walls include front wings extending forward of said central bridge, said connector further including first and second tabs extending inward from said wings and spaced from one another to define a first hook space between said central bridge and said first tab and a second hook space between said first and second tabs, and wherein said lower horizontal seat, first hook space, and tail space define a small hook corridor, said upper horizontal seat, second hook space, and tail space define a medium hook corridor, and said upper horizontal seat, second hook space, and an area below the lower rail face define a large hook corridor. 12. The connector of claim 11 further including a rear bayonet slot and wherein said pin passage is configured to receive one-quarter inch and three-sixteenth inch pin arms. 13. The connector of claim 12 wherein said central bridge includes a front portion and a rear portion longitudinally spaced from one another to define a gap therebetween, said front portion including a first section fixed to said side walls and a movable latch cantilevered from said first section and operably disposed within said pin passage. 14. A wiper blade comprising: a frame; a connector coupled to said frame and adapted to permit selective coupling of a small, medium, and large hook arm, first and second pin arms, and a bayonet arm to said frame, said connector including first and second side walls spaced from one another; a central bridge interconnecting said first and second side walls, said central bridge and first and second side walls defining a pin passage and a rivet passage; and a rail interconnecting said first and second side walls and vertically spaced from said central bridge to define a tail space between said bridge and said rail, said rail having a forwardmost free end positioned rearward of said pin passage and said rivet passage to define a rail-free hook insertion space below said bridge, forward of said pin passage, and between said side walls. 15. The wiper blade of claim 14 wherein said central bridge includes an upper bearing surface and a lower surface, said upper bearing surface being vertically spaced a first distance from said lower surface so that said central bridge is positionable between the body and tail of a small hook arm with the hook tail being above the rail. 16. The wiper blade of claim 15 wherein said connector further includes a step extending along said side walls, said step having an upper surface above said upper bearing surface, said upper surface being vertically spaced a second distance from said lower bearing surface, said second distance being greater than said first distance so that said central bridge is positionable between the body and tail of a medium hook arm with the hook tail being above the rail. 17. The wiper blade of claim 16 wherein said rail includes an upper face and a lower face, and wherein said tail space is between said upper face of said rail and said lower surface of said central bridge. 18. The wiper blade of claim 17 wherein said upper surface of said step is vertically spaced a third distance from said lower face of said rail, said third distance being greater than said second distance so that said central bridge is positionable between the body and tail of a large hook arm with the hook tail of the large hook arm being below the lower face of said rail. 19. The wiper blade of claim 14 wherein said side walls include a rivet slot
