Description
Mobile detailing and field technicians lose production time waiting on single-battery chargers to replenish power. The MetroVac CHV-B6 Black Steel 3-Speed handheld canister vacuum solves field downtime with two interchangeable lithium packs and 250 Watts of suction power. It pulls 60 CFM through a steel housing. Coarse gravel chunks wedge inside the narrow crevice nozzle neck.
The main canister features heavy-gauge cold-rolled carbon steel coated in industrial black powder finish. A balanced aluminum fan impeller couples straight to the 250-watt brushless motor shaft without belts or plastic gears. Viton rubber perimeter gaskets seal the collection drum against the motor housing to maintain peak static lift. Air pathways channel fine debris through a dual-stage washable textile filter before venting through slotted rear exhaust ports lined with acoustic foam.
Deluxe Handheld Hardware System Matrix
Twin battery packs allow continuous work cycles by charging one battery while operating the second. The deluxe tool kit provides specialized attachments for fleet vehicle interiors and machinery cabinets.
- 250-watt brushless motor produces 60 CFM and 55 inches of water lift.
- Heavy-gauge steel construction withstands drops and truck vibration without chassis cracks.
- 3-speed selector switch regulates suction draw to extend battery amp-hour capacity.
- Two 14.4 Volt lithium batteries provide uninterrupted work through battery rotation.
- Multi-piece deluxe attachment kit includes specialized nozzles for intricate equipment crevices.
- Dual-stage textile filter system traps fine dust particles before entering the motor turbine.
- Crush-proof flexible hose links steel extension wands for overhead cab reach.
Dyno Bench Vacuum Telemetry Metrics
On speed setting three, electrical draw registers 17.1 Amps from the 14.4 Volt battery under full suction drag. Turbine velocity peaks at 28600 RPM, producing 54 inches of static water lift across our test bench gauge. Motor casing temperatures climb 29°F through a full 15-minute discharge run, cresting at 123°F. Sound meter telemetry records 72 dBA at 1 meter on maximum power. Airflow drops to 50 CFM once fine dust coats the interior surface of the textile filter bag.
Shop Handling Field Boundaries
At 4.6 pounds with battery attached, this steel handheld operates without wrist fatigue in tight airplane or van interiors. Do not use this dry canister for flooded floorboards, glycol leaks, or hot furnace soot. Liquid intake turns trapped dirt into mud, corrodes the steel canister bucket, and ruins the brushless motor control circuits.
- Empty the steel canister bucket before collected dust reaches halfway up the intake.
- Wash the cloth filter bag in clean water every thirty days and dry for 24 hours.
- Wipe battery terminal pins with a dry shop cloth before locking packs into the chassis.
