Description
Intermittent tool operation demands dust extractors that power up on command to protect workers from airborne debris. The Nilfisk ATTIX 33-21 IC 8 Gallon pairs auto-start tool activation with an 890W motor generating 148 CFM and 92-inch water lift. Standard PTFE filtration limits this model around toxic abatement jobs that mandate certified HEPA containment.
Heavy-wall polyethylene molds the 8 Gallon recovery canister, rejecting corrosive masonry wash liquids and shop impacts. The electrical control board incorporates a current sensor that powers the vacuum motor whenever the operator pulls the connected power tool switch. An InfiniClean solenoid valve pulses reverse air through the PTFE flat filter every 15 seconds to purge fine dust cakes. Bypass turbine cooling tracts isolate copper armatures from dry drywall dust to stop premature brush burn.
Auto Triggered Pulse Matrix
Drywallers and millwork installers run this machine to capture airborne dust straight from track saws and orbital sanders. The antistatic construction prevents static shock discharges in dry work zones.
- Auto-start tool outlet starts and stops the vacuum motor in sync with connected electric hand tools
- InfiniClean automatic pulse system clears the filter every 15 seconds without technician input
- Washable PTFE long-life filter membrane repels fine dust cakes to maintain sustained suction
- 890W commercial motor produces 148 CFM and 92-inch static water lift for fast dust capture
- Antistatic suction hose bleeds static electricity charges to ground during high-speed drywall sanding
- 8 Gallon impact-resistant polyethylene drum survives falls from work benches without cracking
- Flat-top motor cowl provides mounting points for modular contractor tool boxes and accessories
Electrical Load Bench Telemetry
Current draw pulls 7.5 Amps on 120 Volt service under continuous extraction without an auxiliary tool running. Motor cap temperatures climb 35°F over room ambient after 45 minutes of heavy cutting trials. Cooling exhaust air peaks at 115°F during loaded high-vacuum cycles. Suction loss measures 6-inch water lift across the 13-foot antistatic hose run. Acoustic meters register 60 dBA at 10 feet under open airflow, climbing to 65 dBA as the reverse pulse valve cycles.
Field Bounds Service Directives
The 32-pound chassis rolls true across unfinished subfloors, yet tugging the unit by its antistatic hose around sharp drywall corners can snap hose cuffs. Lead paint abatement contractors should pass on this configuration, as non-HEPA PTFE filtration allows microscopic lead flakes to pass through the exhaust. Vacuuming smoldering wood chips or hot metal grinding sparks will melt the antistatic hose liner and ignite the filter.
- Check the antistatic hose cuff for electrical continuity using an ohmmeter once per month
- Wipe down the auto-start outlet face with dry contact cleaner to prevent dust bridging
- Rinse the PTFE filter with low-pressure water and air dry before reinserting for dry sanding
