Description
Corrosive chemical powders and caustic pharmaceutical residues dissolve standard painted steel vacuum containers. The Nilfisk S3N1 L100 AU 2X pairs full AISI 304 stainless steel construction with certified HEPA filtration driven by three 120V bypass motors pulling 285 CFM. Its 160-pound dry weight demands two technicians or mechanical hoists to lift into service trucks.
Food-grade AISI 304 stainless steel forms the filter chamber and the 26 Gallon drop-down container, withstanding acid washes and harsh sanitizers without pitting. An automated electric shaker mechanism vibrates the primary star filter on a set timer to shed caked powders. The secondary certified HEPA filter array stops 0.3 micron particulates from reaching the exhaust. Three independent bypass motors route clean ambient air across field windings, preventing copper commutator corrosion from acidic plant vapors.
Stainless Sanitary HEPA Matrix
Cleanroom facilities, food processors, and chemical labs deploy this stainless 3-motor vacuum for toxic dust containment. Heavy stainless cam latches ensure positive seal compression under maximum three-motor drag.
- AISI 304 stainless steel chamber and drop bin resist acid degradation and wash-down chemicals
- Three independent industrial bypass motors deliver 285 CFM for rapid containment of dense dust
- Certified downstream HEPA filter captures 99.97% of hazardous dust particles down to 0.3 microns
- Automated electric filter shaker clears the primary star filter without manual technician labor
- 26 Gallon stainless drop-down container rolls on independent casters for fast sanitary disposal
- Stainless steel trolley frame with large non-marking wheels rolls over threshold bumps without hang-ups
- Independent motor switches allow customized suction flow to prevent electrical breaker overloads
Dyno Thermal Bench Telemetry
Tri-motor load pulls 18.5 Amps on dedicated 120 Volt service under loaded suction through the HEPA chamber. Motor casing temperatures climb 47°F above room ambient after 50 minutes of continuous chemical extraction. Exhaust air discharge peaks at 127°F under sustained high-vacuum resistance. Static water lift drops 9-inch water lift across a 15-foot conductive hose. Operating noise registers 71 dBA at 10 feet on single motor, rising to 78 dBA with all three motors engaged.
Cleanroom Boundaries Maintenance Rules
The stainless drop container rolls across seamless epoxy floors without marking, but moving a filled 200-pound chemical bin requires careful two-man handling. Facilities operating on standard 15-Amp commercial circuits should not buy this unit without 20-Amp electrical drops installed. Sucking burning metal shavings or reactive flammable solvents will breach the HEPA seals and trigger internal dust explosions.
- Test the automated filter shaker function at the beginning of each sanitation shift
- Inspect the HEPA filter perimeter seal once per week for chemical degradation or powder bypass
- Wash down the stainless drop container with neutral detergent to prevent caustic crusting
