Description
Caustic chemical laboratories and food manufacturing lines require compact stainless suction units that resist acid pitting. The Nilfisk S3N1 L50 AU 2X delivers sanitary certified HEPA filtration through three 120V bypass motors pulling 285 CFM. The 13 Gallon collection container fills fast under continuous powder recovery, requiring frequent drop-bin release during production runs.
Passivated AISI 304 stainless steel forms the filter chamber and the 13 Gallon drop-down collection bin, resisting rust from aggressive wash-down chemicals. An automated electric shaker mechanism vibrates the primary star filter to shed fine dust cakes without manual worker effort. Downstream certified HEPA filter cartridges capture microscopic particulates down to 0.3 microns. Three independent bypass motors vent hot air through sound baffles while pulling isolated ambient air across commutators.
Sanitary Three Motor Matrix
Food plants and chemical packaging rooms utilize this compact stainless vacuum for toxic powder recovery. Robust mechanical cam latches maintain positive gasket seal compression under deep three-motor vacuum pull.
- AISI 304 stainless steel tank and chamber withstand corrosive sanitizers and acid wash-downs
- Three independent industrial bypass motors produce 285 CFM for rapid powder evacuation
- Certified downstream HEPA filtration captures 99.97% of hazardous dust down to 0.3 microns
- Automated electric filter shaker cleans the star filter without interrupting plant workflows
- 13 Gallon stainless drop-down bin detaches via lever for fast roll-away disposal on own casters
- Stainless steel transit cart features non-marking casters that protect finished epoxy floors
- Independent motor power switches prevent electrical overloads on shared industrial circuits
Motor Load Thermal Telemetry
Line current pulls 18.5 Amps on dedicated 120 Volt service under full closed-inlet load conditions. Motor dome metal temperatures climb 46°F above room ambient after 45 minutes of heavy chemical extraction. Cooling air exhaust vents at 126°F under sustained high-vacuum resistance. Static water lift drops 8-inch water lift across a 15-foot conductive hose. Operating sound levels register 71 dBA at 10 feet on single motor, rising to 78 dBA with all three motors engaged.
Cleanroom Limits Maintenance Directives
The compact stainless cart rolls between processing kettles without hang-ups, but dumping a filled 130-pound container into raised waste hoppers requires mechanical tippers. Facilities lacking dedicated 20-Amp circuits must avoid this machine, because three-motor startup draw will trip standard 15-Amp lines. Sucking ungrounded combustible dusts through non-conductive hoses will generate dangerous static charges that bypass the grounded chassis.
- Check the automated filter shaker cycle at the start of each production shift
- Inspect the HEPA filter seal once per week for dust trails that indicate bypass leaks
- Rinse the stainless drop container with clean water after pulling corrosive chemical residues
