Description
Shop floors littered with sharp metal shavings destroy cheap plastic collection drums. The Nilfisk AERO 21-01 PC INOX counters abrasive waste with a stainless steel drum and a 120V motor pulling 125 CFM and 84-inch water lift. Tank volume holds 5 Gallon, creating a choke point on large water extraction jobs that demand nonstop suction.
Corrosion-resistant AISI 304 stainless steel forms the container shell, stopping punctures from sheared sheet metal scrap and hot turnings. The bypass motor configuration isolates electrical carbon brushes from incoming moisture streams, halting arc flash erosion. A semi-rigid polyurethane motor mount cushions high-frequency vibration against the canister top rim. Aluminum turbine vanes balance airflow velocity, preventing blade deformation when suction spikes against a sealed intake port.
Stainless Canister Performance Core
Metal fabrication shops operate this platform to pick up oil sludge, turnings, and coarse grindings. Physical toggle clamps secure the motor head against container seals under continuous shop vibrations.
- 5 Gallon AISI 304 stainless steel canister rejects rust and puncture damage from sharp metal filings
- 120V commercial bypass motor delivers 125 CFM and 84-inch water lift for deep debris pickup
- Push-and-Clean filter cleaning button directs reverse air blasts to dislodge compacted surface cake
- Washable PET fleece filter element maintains 99.9% filtration efficiency without rotting from moisture
- Rubber storage strap secures power cable and flexible suction hose during hand transport
- Multi-piece contractor tool pack provides aluminum extension wands and hard floor shoes
- Steel drum latches exert downforce to preserve gasket seal compression under deep vacuum
Motor Load Thermal Telemetry
Testing on 120 Volt circuits records an 8.4 Amp draw under full closed-inlet load. Motor dome metal temperatures climb 36°F above ambient room levels after 45 minutes of continuous pull. Exhaust air from the cooling discharge port registers 116°F under sustained mechanical resistance. Vacuum lift drops 7-inch water lift when switching from the stock 8-foot hose to a 16-foot run. Sound output meters track 64 dBA at 10 feet under open intake, rising to 69 dBA under high-vacuum restriction.
Jobsite Limits Maintenance Directives
The 19-pound dry weight transfers between service trucks with minimal physical strain, though narrow wheel spacing risks roll-overs across deep floor ruts. Production woodshops cutting continuous MDF sheets must avoid this machine, because non-HEPA filtration bleeds fine airborne dust back into workspace breathing zones. Pulling hot molten slag or burning embers will melt the internal intake deflector and spark canister fires.
- Hit the Push-and-Clean button three consecutive times whenever intake suction drops under heavy dust load
- Inspect the canister rim gasket each week for grit accumulation that degrades suction performance
- Rinse the PET filter cartridge with cold water and dry before returning to dry service
Commercial Warranty Carton Contents
