Description
Service technicians working inside sensitive aircraft cockpits and clean rooms risk FOD hazards from cracking plastic vacs. The MetroVac CHV-S6 Stainless Steel 3-Speed cordless vacuum provides indestructible foreign-object-damage prevention with an all-stainless chassis and precision detail tools. It pulls 50 CFM airflow and 45 inches of water lift. Ingesting standing water will short the brushless motor.
The cylindrical canister consists of stamped surgical-grade stainless steel that resists harsh chemical disinfectants and mechanical impacts. Suction originates from a 250-watt digital brushless motor spinning on dual precision ball bearings. A high-efficiency alloy impeller fan draws air across a sealed multi-stage filtration capsule. Thermal heat sinks draw heat away from the brushless controller, venting warm exhaust air through micro-baffles to maintain safe internal temperatures during high-speed runs.
Hardware Matrix Operational Specs
All-stainless construction eliminates brittle plastic fragments in critical aviation and clean-room environments. Two interchangeable slide-in battery packs provide continuous run time across multi-shift technical aircraft inspections.
- 250-watt digital brushless motor delivers 50 CFM airflow without carbon brush wear.
- Stamped surgical-grade stainless steel canister body withstands harsh chemical disinfectants and drops.
- 3-speed electronic pushbutton switch matches suction force to delicate instrument cleaning.
- Two interchangeable lithium-ion batteries provide non-stop operational rotation across work shifts.
- Dual-voltage fast charging base replenishes battery cell voltage in under 90 minutes.
- Deluxe detailing kit includes flexible extension hoses, micro-crevice nozzles, and horsehair dusting brushes.
- Multi-layer HEPA filtration capsule captures microscopic debris down to 0.3 microns.
Dyno Thermal Bench Benchmarks
A battery load testing console records a 10.4 Amp continuous draw on the battery bus in maximum speed mode. Brushless motor fan velocity stabilizes at 26200 RPM under micro-tool restriction. Stainless steel canister temperatures climb 24 degrees Fahrenheit over ambient room baseline during a complete discharge run. Battery pack cell temperature reaches 110 degrees Fahrenheit at shutdown. Audio meters record 65 dBA on low speed and 71 dBA on high speed. Current sensors halt motor operation within 0.2 seconds of an intake stall.
Field Maintenance Trade Offs
The compact canister design lacks capacity for large floor sweeping tasks, restricting this unit to electronics, vehicle interiors, and precision detailing. Never use this dry vacuum on standing liquids or chemical puddles because fluid destroys the brushless controller board. The stainless steel body requires wiping to remove hand oil marks.
- Allow hot lithium battery packs to cool before insertion into the dual-bay charger.
- Blow clean the stainless mesh pre-filter with dry air after picking up fine carbon dust.
- Wipe the stainless steel canister exterior with an approved disinfectant towel each shift.
