Description
School classrooms and library carpets hold fine sand that stationary floor tools skate over without extracting. The NaceCare Solutions ProVac PPR 380 canister vacuum adds an air-driven AST3 turbine powerhead to a 4.5-gallon commercial drum. It moves 100 CFM on 120 Volt circuits. Thick plush carpet bogs down the turbine rotor and stops roller agitation dead.
The outer drum uses thick-wall rotomolded polypropylene to withstand heavy kicks and doorway strikes without punctures. An energy-efficient 680-watt motor spins an aluminum impeller wheel inside an acoustically insulated motor dome. The AST3 powerhead houses an internal air turbine connected to a cogged belt that drives a nylon bristle brush roller without electrical wires. Air routes through a large TriTex cloth basket and HepaFlo micro-bag, preventing abrasive dust from scoring motor armature bearings.
Turbine Powerhead Hardware System Matrix
Air-driven agitation strips ground-in dirt from commercial rugs without requiring heavy electric wands or specialized cables. The internal cord rewind reel eliminates tangles during long-distance corridor cleaning.
- 680-watt commercial motor delivers 100 CFM and 100 inches of static water lift.
- AST3 air-driven powerhead agitates carpet fibers to pull up deep-seated sand.
- 4.5-gallon structural drum holds high debris volume to minimize waste emptying stops.
- Internal rewind reel stores the 33-foot power cord inside the powerhead casing.
- TriTex primary cloth filter captures fine dust down to 0.5 microns.
- HepaFlo self-sealing dust bags eliminate airborne dust clouds during disposal.
- Stainless steel extension wands provide rigid downward force without bending.
Dyno Bench Vacuum Telemetry Metrics
Continuous floor testing on 120 Volt service pulls 5.8 Amps with the AST3 turbine head running on low-pile carpet. The 680-watt motor maintains 19500 RPM while pulling 96 inches of static water lift on our test manometer. The air turbine spins the brush roller at 3200 RPM under continuous suction. Motor dome temperatures climb by 26°F across 60 minutes of uninterrupted cleaning, leveling at 120°F. Sound meter telemetry registers 52 dBA at 1 meter distance with the turbine running.
Shop Handling Field Boundaries
Weighing 15.5 pounds with the turbine tool attached, this canister rolls behind technicians on rubber-tread wheels without scuffing gym floors. Do not use this dry vacuum for wet mop recovery, flooded basements, or boiler soot. Moisture rots the TriTex filter basket, seizes the AST3 turbine bearings, and burns out the commercial motor.
- Clear caught thread and hair from the AST3 turbine brush roller every week.
- Shake out the TriTex primary filter basket after every five bag changes.
- Inspect the rewind cord for jacket cuts or copper fatigue every thirty days.
Commercial Warranty Delivery Manifest
NaceCare backs the ProVac PPR 380 with a 5-Year commercial motor warranty and 2-Year coverage on the canister drum and electrical parts. The kit contains the 4.5-gallon vacuum, a 33-foot rewind cord, a crush-proof hose, stainless steel wands, and the AST3 air-driven powerhead kit.
