Description
Field technicians crack brittle plastic hand vacuums when servicing heavy industrial equipment and conveyor control panels. The MetroVac VM4B500 Vac N Go handheld vacuum eliminates plastic breakage through a rugged all-steel canister frame and a high-output 500-watt commercial motor. It produces 65 CFM airflow and 60 inches of water lift. Ingesting liquid spills will short the armature.
The body uses stamped 20-gauge carbon steel finished in high-durability black powder coat that resists dents from dropped tools. Inside, a 500-watt 0.75-horsepower commercial motor operates on precision ball bearings balanced to suppress hand vibration. A high-velocity suction fan draws air through a sealed cloth and paper filtration array. Internal cooling channels route ambient air across the electrical stator, venting heat through perimeter louvers to keep the steel shell comfortable to hold.
Hardware Matrix Operational Specs
All-steel construction withstands severe mechanical trauma that shatters consumer plastic vacuums on industrial job sites. The comprehensive attachment kit connects via slip-fit friction collars to reach tight machinery compartments and vehicle tracks.
- 500-watt 0.75-horsepower commercial motor delivers 65 CFM airflow for aggressive dry debris extraction.
- Stamped steel canister chassis eliminates body cracking when dropped onto concrete shop floors.
- Disposable paper collection bags capture fine grit down to 0.3 microns to protect exhaust air.
- 19-inch flexible suction hose flexes into tight automotive seat tracks and machinery compartments.
- Pik-All nozzle with nylon bristles agitates dust off rough industrial shelving and control boxes.
- 12-foot heavy-duty commercial power cord provides ample reach around service benches.
- Removable shoulder strap permits hands-free climbing on ladders and service scaffolding platforms.
Dyno Thermal Bench Benchmarks
A calibrated shop load tester records a 4.2 Amp continuous draw on a 120-volt power feed under full tool restriction. Motor velocity tops out at 23500 RPM in open suction mode. Steel canister surface temperatures rise 36 degrees Fahrenheit over ambient room baseline during a 45-minute continuous run. Static suction lift holds at 60 inches of water lift on clean bags, dropping to 50 inches when filled. Sound meters register 72 dBA at 3 feet from the steel canister. Built-in thermal limiters trip at 205 degrees Fahrenheit during air blockages.
Field Maintenance Trade Offs
The compact steel canister lacks capacity for large floor sweeping assignments, limiting this unit to service benches, vehicles, and detail work. Never use this machine for wet extraction or post-construction drywall cleanup because moisture will short the unsealed motor and fine plaster ruins the paper filter. The steel shell gets warm during extended use.
- Replace the paper filter bag when dry debris reaches two-thirds capacity to preserve airflow.
- Inspect the secondary cloth permanent filter for fabric tears every 30 run hours.
- Wipe the steel canister exterior with a clean dry towel to prevent grime accumulation.
