Quick, Clean & Automated Refill of Single, Twin Screw, Vibratory and Belt Feeders

VAC-U-MAX Vacuum Conveying Systems offer the quickest and cleanest option for refilling volumetric or gravimetric feeders used in batch and continuous processes. Many times the feeder is purchased without consideration of how the feeder will get filled and refilled. Vacuum receivers easily integrate for volumetric feeder refill applications. The “keep full” operation of the VAC-U-MAX receiver meters material to the feeder by immediately discharging material into the hopper when the feeder reaches a low-level signal. The refill process occurs in seconds with the VAC-U-MAX receiver always maintaining a charge of material ready for dispensing into the feeder. The process will repeat itself until all the material has been conveyed or when the operator turns off the control panel. Sanitary designs are available and ideal for applications in the food, pharmaceutical and packaging industries. Stop by booth 1219 to preview a working demonstration featuring a VAC-U-MAX vacuum conveyor refilling an Acrison feeder.  


Processing Mobility with Mobile Vacuum Conveying Systems 

VAC-U-MAX Mobile Vacuum Conveying Systems offer ease-of-mobility for applications requiring access to tanks or other hard-to-reach processing areas. System incorporates an adjustable suction wand where operator introduces product to the vacuum system. Mobile frame incorporates the vacuum producer, conveying product up to 5,000 pounds (2,268 kg) per hour and beyond. Vacuum receiver is manually hoisted for easy up-and-down mobility, to a height of at least 91” (231 cm) at the  discharge point, or down to operator level for easy disassembly, cleaning and transport. Vacuum receiver includes replaceable inlet assemblies, easy access to filters, pulse filter cleaning, and full opening discharge valves. Vacuum power source includes air-powered venturi system, regenerative blower package, or positive displacement vacuum pump. Control panel is mounted on the rolling frame and handles the convey, discharge and filter cleaning functions of the system.  All Mobile Vacuum Conveying System are USDA-accepted in stainless steel, and available in carbon steel. All receivers meet the rigid requirements of the food and pharm industries. Stop by booth 1316 for a demonstration.

NFPA-Compliant Industrial Vacuum Cleaning Systems for Powders and Combustible Dusts 

VAC-U-MAX product line includes a full range of portable and central industrial vacuum cleaning units and systems, engineered for specific applications that address issues like worker exposure to dusts, chemical compatibility, flammability, and combustibility. An expert at combustible dust handling, VAC-U-MAX industrial vacuum cleaning systems are available for a wide range of applications. Models on display include: 

MDL15: Combustible Dust Air-Vac for Fine Powders / Dusts

The MDL15 is designed with a VAC-U-MAX venturi power unit, proven to have the lowest compressed-air consumption in its product class. The MDL15 fills a niche between VAC-U-MAX’s 5-gallon hand-held vacuum and the 30-gallon model for combustible dusts, featuring a static-conductive PTFE primary filter and secondary cartridge filter. Unit collects powders and dusty debris in off-the-shelf static-conductive polybags eliminating the mushroom cloud associated with drum dumping. Standard construction is 304SS / 316SS with bead-blast finish, with unit suitable for food environments. MDL15 is ATEX-approved and equipped with static-conductive compressed air hose, casters, ATEX-certified vacuum hose and complete cleaning tool kit. Visit for more information.
