Description
Hazardous particulate remediation leaves zero room for substandard dust filtration or ruptured collection drums. The Nilfisk AERO 21-01 PC INOX HEPA captures lead paint chips and silica dust through a certified HEPA system pulling 125 CFM and 84-inch water lift. Canister capacity tops out at 5 Gallon, requiring constant interruptions to dump debris on large construction zones.
Drawn 304 stainless steel forms the collection drum, deflecting sharp scrap and abrasive masonry chunks without wall puncture. The HEPA filter element seats against an airtight rubber gasket, preventing toxic dust bypass around the motor intake. Dual cooling paths direct clean air across motor windings while exhausting vacuum air through separate side baffles. Precision balanced motor impellers limit shaft deflection under peak load, extending front bearing lifespan under heavy dust extraction cycles.
Abatement Filtration Hardware Matrix
Contractors use this machine for OSHA-compliant silica containment around drills, grinders, and small concrete saws. Mechanical components isolate dangerous dust particles from surrounding air spaces.
- Certified HEPA filter captures 99.97% of toxic dust particles down to 0.3 microns
- 5 Gallon stainless steel drum withstands abrasive masonry waste without wall corrosion or wear
- 120V commercial motor pulls 125 CFM to evacuate dust shrouds on power tools
- Push-and-Clean button pulses air backwards through the cartridge to shake off surface cakes
- Heavy rubber tie-down strap anchors the hose and electrical cord during transport
- Multi-piece tool kit includes aluminum wands and commercial floor nozzles for fast cleanup
- Steel drum clamps maintain positive downforce to prevent airborne bypass around the seal
Thermal Dyno Load Telemetry
Bench testing on 120 Volt power draws 8.5 Amps under sustained suction through a clogged test port. Motor housing metal temperatures rise 37°F above ambient after 50 minutes of continuous dust collection. Filter exhaust air registers 118°F when pulling against a loaded HEPA cartridge. Suction drop measures 9-inch water lift when adding a 15-foot hose extension to the inlet. Sound level meters record 64 dBA at 10 feet under open airflow, reaching 69 dBA under high resistance.
Field Restrictions Maintenance Protocol
Lightweight 19-pound construction allows one-hand carrying up scaffolding, yet the narrow wheel base tips over if pulled sideways over electrical cords. Demolition outfits stripping full building drywall spans should pass on this small unit, as small filter surface areas plug fast under massive sheetrock loads. Sucking hot boiler soot or live chimney embers will burn the HEPA membrane and destroy seal gaskets.
- Depress the Push-and-Clean button three times whenever tool suction begins to drop
- Check the HEPA cartridge sealing gasket per shift for dirt paths indicating air bypass
- Replace the fleece collection bag before dust reaches two-thirds container capacity to preserve airflow
Warranty Coverage Package Components
Nilfisk covers the powerhead and electronics with a 2-Year commercial warranty. The unboxed container delivers the stainless steel vacuum, certified HEPA filter, fleece bag, 11-foot suction hose, two aluminum extension tubes, floor tool, crevice nozzle, and universal rubber power tool adapter.
