Description
Planetary floor grinders generate massive clouds of respirable crystalline silica that blind standard shop filters within seconds. The Onfloor Dynavac Pro 2000 Dust Collector vacuum provides continuous negative pressure extraction paired with certified HEPA filtration on 120 Volt single-phase power. Built for concrete prep, this heavy steel extractor controls hazardous dust, but its tall cyclonic chamber limits transit inside standard compact vans.
Rolled 12-gauge carbon steel forms the cyclonic drop chamber, deflecting abrasive masonry aggregate downward before particulate strikes the filter pleats. Dual bypass vacuum motors sit inside an acoustically insulated motor dome, cooling armatures through dedicated intake vents. A conical primary filter works in series with a downstream certified HEPA cartridge, sealing microscopic mineral dust inside the drop chamber through closed-cell polyurethane perimeter gaskets.
Concrete Silica Collection Profile
Concrete surface grinding requires high-volume suction to protect operator lungs from toxic respirable dust. This dual-motor extraction platform pairs cyclonic separation with pulse-cleaned micro-filtration hardware.
- Twin 120 Volt Industrial Bypass Motors produce high suction velocity to clear aggressive floor grinder shrouds.
- Certified Downstream HEPA Filter captures 99.97 percent of microscopic silica dust down to 0.3 microns.
- 12-Gauge Rolled Steel Cyclonic Body drops heavy concrete chips before particulate contacts the filter media.
- External Mechanical Filter Shaker knocks cake buildup off filter pleats without releasing toxic dust plumes.
- Drop Down Longopac Continuous Bagging Attachment enables zero-contact disposal of hazardous masonry debris.
- Heavy Tubular Steel Transport Trolley incorporates large rear wheels for transit across rough slab expansion joints.
- 2-Inch Camlock Steel Intake Port prevents wall wear from high-velocity mineral sand impact.
Grinding Bench Telemetry Output
Electrical load monitoring on 120 Volt circuits logs 15.8 Amps with both bypass motors engaged under heavy grinding resistance. Motor housing surface temperatures reach 154°F after 90 minutes of continuous concrete extraction in a 75°F test bay. Static lift gauges register 105 inches of water column alongside 220 CFM open airflow. Sound monitoring instruments log 75 dBA at 5 feet. Differential pressure gauges verify that the primary filter shaker restores 88 percent of original airflow after clearing dense silica cake.
Surface Prep Fleet Guidelines
The wide rear wheels roll over jobsite debris without hang-ups, but tipping this 145-pound machine into pickup beds requires two operators and ramps. Concrete restoration crews and terrazzo specialists gain dependable silica control, but operators vacuuming wet floor slurry will saturate the dry filters and short out the bypass motors.
- Actuate the mechanical filter shaker lever after every 20 minutes of active concrete grinding.
- Inspect the Longopac continuous bag retention band each week for tension loss or tears.
- Check the lower cyclonic rubber drop flap every 30 days to prevent negative pressure leaks.
