Description
General construction cleanup and woodworking shops generate massive chip volumes that choke undersized vacuum canisters. The Nilfisk ATTIX 44-21 IC 11 Gallon wet dry vacuum handles bulk sawdust and shop debris through an 890W motor generating 148 CFM. Non-HEPA filtration restricts this machine from certified lead paint abatement and regulated toxic dust remediation tasks.
High-density polyethylene forms the rigid 11 Gallon canister, deflecting rough timber impacts, dropped hand tools, and shop chemicals without denting. The onboard power tool outlet incorporates an electronic sensing switch that triggers the vacuum whenever the operator fires an electric miter saw. An InfiniClean reverse-pulse valve shocks the PTFE flat filter with reverse atmospheric air every 15 seconds. Isolated bypass cooling tracts shield motor brushes from airborne sawdust to avoid brush arcing and thermal breakdown.
Production Woodworking Hardware Matrix
Carpenters and cabinetmakers connect shop machinery straight to this unit for synchronized dust extraction at the blade guard. Durable mechanical components handle coarse wood chips and shavings without air path clogging.
- 11 Gallon structural polyethylene canister holds high debris volumes for reduced disposal downtime
- Auto-start tool socket powers the vacuum motor in sync with connected handheld wood tools
- InfiniClean automatic filter cleaning pulses reverse air every 15 seconds to shed caked dust
- Washable PTFE non-stick flat filter membrane resists moisture rot and fine particulate blinding
- Antistatic suction hose prevents electrostatic charge build-up during dry chip and dust extraction
- 890W industrial motor delivers 148 CFM and 92-inch water lift for high-velocity chip collection
- Tough rear transport wheels navigate across cord clusters and workshop scrap without hanging up
Dyno Load Telemetry Data
The motor pulls 7.5 Amps on 120 Volt service under continuous extraction without an auxiliary tool running. Motor cap metal temperatures climb 35°F above ambient after 45 minutes of heavy cutting trials. Cooling exhaust air vents at 115°F during loaded vacuum runs against restricted tool shrouds. Suction loss measures 6-inch water lift across the 13-foot antistatic hose run. Operating sound levels register 60 dBA at 10 feet under open airflow, peaking at 65 dBA during pulse cycles.
Usage Boundaries Upkeep Directives
The 35-pound chassis maneuvers across woodshop floors without hassle, but tipping the unit to dump fine sawdust can kick up nuisance dust clouds. Toxic asbestos remediation contractors must not purchase this model, because non-HEPA filtration allows hazardous microscopic fibers to pass into room air. Pulling hot wood stove ash or burning metal sparks will burn through the fleece bag and melt the PTFE membrane.
- Tap out coarse shavings from the filter frame and inspect the PTFE membrane once per week
- Check the auto-start power socket for dust accumulation and clean with dry contact spray
- Wash the PTFE flat filter with cold tap water and dry to a crisp finish before dry service
