Description
OSHA Table 1 compliance requires verified HEPA filtration coupled straight to masonry cutting and grinding tools. The Nilfisk AERO 26-21 PC HEPA satisfies certified containment standards with a 120V motor generating 125 CFM and 84-inch water lift. Collection volume holds 6.6 Gallon, demanding frequent bag swaps on high-production concrete floor grinding jobs.
The collection canister uses structural polyethylene molding to resist stress cracking from drops and caustic construction site moisture. An auxiliary tool socket features auto-start sensor circuitry that powers the vacuum whenever the operator engages the connected hand grinder. The certified HEPA filter element seats within a closed cell elastomer gasket, blocking toxic dust bypass into the motor air path. Isolated bypass motor fans pull clean ambient air across copper commutators to prevent premature brush wear.
Certified Containment Hardware Matrix
Restoration contractors and masonry trades deploy this vacuum for point-of-origin silica dust extraction. Rugged mechanical latches maintain constant pressure against the internal HEPA seal under heavy jobsite abuse.
- Certified HEPA filter captures 99.97% of hazardous dust particles down to 0.3 microns
- Auto-start power tool outlet syncs vacuum run time with connected saws and grinders
- 6.6 Gallon polyethylene container withstands rough vehicle transit and dropped tools without cracking
- 120V motor delivers 125 CFM and 84-inch water lift for deep dust shroud evacuation
- Push-and-Clean reverse air pulse system clears dust cakes from the filter face on demand
- Flexible rubber strap anchors the power cord and suction hose during single-hand carry
- Multi-piece tool kit includes aluminum wands, floor tools, and a universal power tool adapter
Thermal Dyno Telemetry Data
Motor current draws 8.5 Amps on 120 Volt service under loaded suction without an auxiliary tool running. Motor cap temperatures climb 38°F over room ambient after 50 minutes of uninterrupted dust extraction. Internal exhaust air hits 117°F when operating through a loaded HEPA filter element. Vacuum drop records at 9-inch water lift across the 11-foot antistatic hose run. Acoustic meters register 64 dBA at 10 feet under open airflow, rising to 70 dBA under high resistance.
Field Bounds Upkeep Directives
The 20-pound weight allows easy transport up stairwells and scaffolds, yet the lightweight front casters snag on discarded framing nails and cords. Abatement crews stripping thick fireproofing spray should pass on this unit, as wet fibrous glues blind the HEPA element without delay. Vacuuming smoldering joint compound or hot grinder spark showers will burn through the fleece containment bag.
- Pulse the Push-and-Clean button three times at every tool bit change to clear filter cakes
- Inspect the HEPA seal gasket once per week for dust penetration paths behind the filter element
- Replace the fleece containment bag before it exceeds two-thirds capacity to protect HEPA lifespan
