Description
Pull deep vacuums on commercial refrigeration circuits without dragging heavy extension cords across rooftops. The Makita 18V X2 36V LXT dual-battery vacuum pump delivers cordless evacuation performance for HVAC technicians. Two 18-volt batteries power the dual-stage rotary vane mechanism. The 4.0-CFM displacement speed slows down evacuation times on massive industrial chillers.
A cast aluminum housing encloses the dual-stage compression chambers to shed heat under continuous load. The brushless DC motor connects straight to the pump shaft without internal gear reductions. Hardened steel vanes compress refrigerant vapors inside precision-ground cylinders. An internal check valve stops oil backflow into refrigeration lines during sudden battery discharge. A drain port allows clean fluid flushes from the pump sump.
Cordless Vacuum Hardware Capabilities
HVAC technicians evacuate commercial rooftop AC splits without generator cords. Dual battery circuits switch between packs to maintain steady pump rotation.
- Dual 18-volt battery ports draw from 36-volt power lines for prolonged runtime
- Two-stage rotary vane pump achieves deep 20-micron ultimate vacuum levels
- Machined aluminum sump casing dissipates heat to extend internal vane life
- Internal check valve blocks pump oil migration into external copper piping
- Gas ballast valve purges moisture vapors to stop oil reservoir contamination
- Standard 5/16-inch brass flare inlet port hooks straight to HVAC manifolds
- Large sight glass provides instant visual verification of pump oil clarity
Vacuum Dyno Bench Telemetry
Bench testing demonstrates the brushless motor draws 8.8 Amps across 36-volt circuits during deep pull-down cycles. The pump evacuates a 10-gallon test vessel down to 200 microns within 14 minutes. Crankcase oil temperature stabilizes at 138°F after 60 continuous operational minutes. Acoustic sensors record 65 dBA at 1 meter distance from the exhaust port. Dual 5.0-Ah battery packs sustain continuous vacuum draw for 62 minutes before low-voltage cutoffs engage.
Worksite Demands Practical Realities
You carry this compact pump up exterior building ladders using the balanced top handle. The broad base plate stays stable on pitched metal rooftops. Do not use this vacuum pump to clear water from flooded basements. Liquid water ingestion destroys internal rotary vanes and washes lubricating oil off metal cylinder walls.
- Inspect vacuum oil clarity through the sight window before connecting hoses
- Open the gas ballast valve during the initial stage of system evacuation
- Seal inlet caps between jobs to prevent atmospheric dust entering the chamber
Commercial Warranty Manifest Terms
Makita backs the tool body and brushless motor with a 3-Year limited warranty. The packaging contains the bare-tool vacuum pump, 5/16-inch flare adapter, 500-milliliter bottle of vacuum pump oil, and the original instruction guide.
