tenance or material changes. Optional blowback feature on ML Series motors provides an adjustable cleaning cycle to prolong filter life. MR Series receivers are designed to operate as part of a central vacuum- conveying system, with material delivered through a top-mounted vacuum-sequencing valve that can swivel in any direction to simplify hose installation. A quick-discon- nect clip opens the hinged lid, swinging the vacuum valve out of the way for easy access to the receiver body and filter screen. The MR-1 receiver has a material-holding capacity of 1 lb, while the larger MR-2 receiver has a 5-in.-tall glass extension that increases its capacity to 2 lb. A discharge valve on the bottom of the receiver incorporates a demand switch that automatically replen- ishes the receiver and hopper. In addition, Conair showed off its new PowerFill 8 mini central vacuum systems, which can deliver material to up to eight destinations. Three models have maximum throughputs from 900 to 3200 lb/hr over maximum tubing lengths from 100 to 225 ft. Mounted on two wheels and featuring an Allen- Bradley PLC and 7-in. touchscreen, these units can link to Conair receivers and valves via plug- and-play electrical and communi- cations cables. Users can select single-material, ratio, volume, and time-fill loading, as well as an idle-mode valve, which allows the vacuum pump to continue running between loading cycles to reduce the number of pump stop-start cycles, which prolongs pump life. 724-584-5500 • Conair's MedLine MR Series receiver.
