All vacuums feature ETL-certification and are designed to meet NFPA 652 housekeeping recom- mendations for the safe collection of combustible dust, as laid out in Section 8.4.2.2. Machine design requirements to ensure NFPA 652 compliance include a stainless steel collection container, antistatic main filter, antistatic wheels and a variety of measures to ensure bonding and grounding throughout the unit. Nilfisk Inc., Morgantown, PA 800-645-3475 www.nilfiskindustrialvacuums.com Level Control and Plugged Chute Detector The Model DLC is a flush-mount, pressure-activated, diaphragm- style level control and plugged chute detector. It has two dry (unpowered) 15-amp micro- switches that activate when mate- rial within the bin or chute presses upon the diaphragm face. It should be mounted on the vertical side wall of the bin, hopper, or chute. It may also be mounted on the sloped portion of the chute, as long as material flows freely or does not "bridge." The Model DLC can be used as a high level switch, a low level switch, or a plugged chute detector. It can also operate as a material presence control on a conveyor belt, and a high level indi- cator above a crusher box.
