This is a refrigerant recovery machine designed for recovering refrigerant during service, maintenance, and system changeout work. Model Number: \u003cstrong\u003e2938-21\u003c\/strong\u003e. If your day involves moving from unit to unit and you are tired of looking for power before you can even start, this setup solves that problem with M18 battery power and a job-ready kit right out of the box.\u003c\/p\u003e \u003cp\u003eThe big story here is speed to setup. Milwaukee built this unit to eliminate cords and outlet hunting, which matters on rooftop work, exterior condensers, commercial service calls, and anywhere power access is inconvenient or unreliable. The included M18 REDLITHIUM FORGE HD12.0 battery means the machine is ready to work as a cordless HVAC recovery tool the moment it comes out of the box, and the included rapid charger keeps the platform practical for techs already invested in M18.\u003c\/p\u003e \u003cp\u003eMilwaukee also gave this machine the controls that actually matter in the field. The adjustable low-pressure shutoff can be triggered at 0 PSIG, -10 inHg, or -20 inHg. That gives the user more control over how the refrigerant recovery process finishes, instead of forcing one fixed setting for every application. There is also a high-pressure shutoff for added system protection, and the LCD digital screen makes it easier to read levels and settings in daylight conditions where small displays usually become a headache.\u003c\/p\u003e \u003cp\u003eFrom a hardware standpoint, this model uses a brushless motor and twin-cylinder design. Milwaukee calls out a vapor recovery rate of \u003cstrong\u003e0.73 lbs\/min with R-410A\u003c\/strong\u003e, and the machine is capable of recovering up to \u003cstrong\u003e10 pounds of refrigerant\u003c\/strong\u003e. Those numbers make it a serious piece of service equipment for field techs who need cordless convenience without stepping down to a light-duty platform. The balanced carrying handle is not filler either. At \u003cstrong\u003e20.5 lbs\u003c\/strong\u003e, this is the kind of machine where handle placement directly affects how annoying it is to carry across gravel, through mechanical rooms, or around a building.\u003c\/p\u003e \u003cp\u003eJobsite practicality is clearly part of the design. Milwaukee includes replaceable mesh filters, and the machine is built with a battery door interlock as part of its A2L-compatible design. For shops and techs dealing with updated refrigerant requirements, that compatibility matters. The body material is listed as glass-filled nylon, which is a smart choice for a field machine that gets loaded, unloaded, and bumped around service vehicles and equipment pads.\u003c\/p\u003e \u003cp\u003eSystem-wise, this machine runs on the \u003cstrong\u003eMilwaukee M18 platform\u003c\/strong\u003e. That matters because it fits into a battery system many contractors already own, and Milwaukee specifically positions it alongside the \u003cstrong\u003eM18 FUEL 5 CFM Vacuum Pump\u003c\/strong\u003e to create a fully cordless service-call setup. If you are building out a cordless HVAC workflow, that pairing is one of the more practical reasons to look at this machine over a corded alternative.\u003c\/p\u003e \u003cp\u003eWho is this for? HVAC technicians, refrigeration techs, service contractors, and serious maintenance departments that want to cut setup time and reduce dependence on shore power. If most of your work happens in one fixed shop bay with easy power access, a corded machine may still be fine. But if your work is mobile and you want cleaner, faster service-call workflow, this Milwaukee recovery machine makes a strong case.\u003c\/p\u003e \u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e \u003csummary\u003e\u003ch2\u003eMilwaukee 2938-21 M18 Brushless Refrigerant Recovery Machine on Service Calls\u003c\/h2\u003e\u003c\/summary\u003e \u003cdiv class=\"acc-body\"\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/www.milwaukeetool.com\/--\/web-images\/sc\/1a6e842b2d994fb4b3ddf36ddd951912?hash=c8386b7b68035b8f907201d709051056\u0026amp;lang=en\" alt=\"Milwaukee 2938-21 M18 Brushless Refrigerant Recovery Machine connected during an outdoor HVAC service call beside an air conditioning condenser and recovery tank on a gravel work area\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eThis is where a cordless refrigerant recovery machine earns its keep.
