Description
HVAC field mechanics drag heavy extension cords across commercial roofs to power corded recovery pumps. The Milwaukee M18 Brushless Refrigerant Recovery Machine Kit recovers liquid and vapor refrigerants on cordless M18 battery power. Sized for field service technicians, it handles tough recovery jobs. Cordless run time remains limited to battery capacity on long system pulls.
The pump houses a twin-cylinder oil-less compressor constructed with ceramic cylinder liners and high-temperature composite piston rings. A brushless DC motor drives the pistons direct, transferring power without friction-generating carbon brushes. High head pressure strains recovery pumps. This pump utilizes integrated liquid refrigerant metering valves that prevent liquid slugging from hydro-locking compressor valves, ensuring continuous flow during rapid push-pull liquid recoveries across high-pressure R-410A refrigeration systems.
Cordless Refrigerant Recovery Hardware Matrix
Field HVAC technicians recover refrigerants from rooftop air conditioners and walk-in coolers. Cordless battery power eliminates extension cord voltage drops on remote rooftops.
- Brushless DC motor delivers high recovery speed while extending battery runtime across commercial rooftop units.
- Twin-cylinder oil-less compressor handles both liquid and vapor refrigerants without internal oil contamination.
- Liquid slugging protection valve meters high-pressure liquid flow to prevent compressor valve head damage.
- High-pressure shutoff switch cuts pump power at 550 PSI to prevent recovery tank over-pressurization.
- Integrated carry strap and compact chassis allow single-hand transport up rooftop access ladders.
- Digital pressure gauges display system suction and tank head pressures for real-time monitoring.
- Compatible with Class 3, 4, and 5 refrigerants including common R-410A, R-134a, and R-22 blends.
Refrigerant Recovery Bench Telemetry Data
Bench recovery testing on R-410A vapor records a pull rate of 0.55 pounds per minute, surging to 12.5 pounds per minute during liquid push-pull operations. An M18 REDLITHIUM HIGH OUTPUT 12.0 Ah battery provides 38 minutes of continuous heavy vapor pull under summer ambient temperatures of 95°F. Compressor head temperature stabilizes at 148°F under continuous 450 PSI discharge pressure. Acoustic noise measures 76 dBA at 3 feet from the housing. Electrical current draw averages 16.5 Amps DC from the battery pack.
HVAC Field Service Work Boundaries
Never run this recovery machine without an inline filter drier on the intake port because acid and copper shavings will ruin compressor valves. Do not purchase this cordless unit for continuous whole-building industrial chiller recoveries where massive multi-horsepower station pumps are required. Over-pressurizing recovery tanks causes dangerous rupture hazards.
- Purge residual refrigerant from the machine after each job using the self-clearing valve feature.
- Replace the inlet particle debris screen every 30 days of active field recovery work.
- Keep motor cooling vents clean of dust and rooftop grit per week using compressed air.
