Description
High-volume concrete grinding overwhelms small vacuums and forces crews to stop work for frequent tub emptying. The Makita GCV04PMUX 40V Max XGT cordless dry dust extractor kit expands capacity to 4 gallons for heavy jobsite cleanup. It runs on 40V max battery power. Running twin grinders off this single vacuum cuts air velocity below OSHA silica standards.
The large-capacity canister tub uses rugged antistatic polypropylene to eliminate static spark discharge while collecting masonry powder. A commercial brushless motor mounts inside an acoustic isolation cage, driving a precision aluminum suction fan. Makita incorporates an automatic internal filter-cleaning mechanism that pulses the pre-filter during operation. Heavy metal latches secure the powerhead against an elastomeric perimeter gasket, maintaining an airtight vacuum seal under extreme jobsite vibration and dragging.
High Capacity Extractor System
This complete kit provides extended capacity for commercial masonry crews seeking cordless OSHA Table 1 compliance. Automated wireless pairing coordinates extractor suction with cordless tool trigger pulls.
- 40V max brushless motor produces 148 CFM and 92 inches of static water lift.
- Auto-Start Wireless System communicates with cordless power tools via Bluetooth signals.
- Automatic filter clean system pulses the filter to prevent suction loss from fine dust.
- 4-gallon dry collection canister reduces dump intervals during heavy concrete grinding.
- Certified HEPA filtration system captures 99.97 percent of particles down to 0.3 microns.
- Variable suction speed dial regulates power across five levels to extend runtime.
- Dual port rapid charger replenishes two 4.0 Ah batteries in 45 minutes.
Dyno Telemetry Bench Metrics
Running on speed five, the brushless motor draws 28.2 Amps from the 40V max 4.0 Ah pack under full suction load. Turbine impeller velocity measures 22500 RPM while maintaining 142 CFM through the 1-1/2-inch antistatic hose. Motor housing temperature climbs by 34°F over a 28-minute discharge run, cresting at 130°F. Operating noise levels read 66 dBA at 1 meter distance. The automatic filter shaker mechanism triggers an audible pulse that clears caked concrete dust without motor stall.
Jobsite Handling Maintenance Limits
Weighing 22.5 pounds with batteries installed, this 4-gallon unit rolls on heavy rear wheels across rough plywood subfloors. Do not use this dry extractor for flooded basements, wet core drilling, or slurry trenching. Moisture ruins the auto-clean mechanism, destroys the dry HEPA filters, and short-circuits the internal electronic pulse board.
- Inspect the automatic filter pulse valve for dust blockage every 50 run hours.
- Clean the antistatic hose grounding pins with a wire brush every month.
- Wipe battery terminal ports with a dry cloth before sliding packs into position.
