Makita MAC2400 Big Bore 2.5 HP Air Compressor
Makita MAC2400 Big Bore 2.5 HP Air Compressor
Makita’s 2.5 HP Air Compressor is equipped with Makita’s Big Bore engineered pump cylinder and piston for higher output for two nailers, with less noise and improved job site performance. The MAC2400 delivers industrial power and results with improved durability under tough job site conditions.
2.5 HP with Big Bore Engineered Pump
The tool and instrument MAC2400 is powered by a 2.5 HP motor. The Makita Big Bore engineered pump with cast iron cylinder has greater bore and stroke for increased compression, faster recovery and less noise. The cast iron construction is engineered for increased durability even under tough job-site conditions. The MAC2400 has an oil-lubricated pump and is equipped with a large automotive style filter for increased air intake and greater efficiency. The Big Bore oil-lubricated pump is also more efficient: the MAC2400 runs cooler and at half the RPM of most competitive units, resulting in greater motor and pump life and lower noise.
The 4.2 gallon twin-stacked tank sustains an operating pressure of 130 PSI, and delivers 40PSI (4.8 CFM) and 90 PSI (4.2 CFM), enough for two nailers. The low AMP draw reduces instances of tripped breakers and voltage drop that can cause premature motor failure. The roll bar handle provides portability and additional protection, helping it withstand harsh jobsite environments. Additional features include a convenient oil drain and oil sight glass, a tank drain valve that supersedes standard petcock design for easier maintenance, and finned discharge tubing that dissipates heat more efficiently.
Versatile Design for a Range of Applications
Makita MAC2400 Big Bore 2.5 HP Air Compressor is engineered for low noise, high output and less maintenance, and delivers industrial power and results with improved durability under tough job site conditions. The MAC2400 is just another example of Makita’s commitment to innovative technology and best-in-class engineering.
Makita MAC2400 Big Bore 2.5 HP Air Compressor Reviews
Best in class 
I think it’s the best for the following:
A) This compressor just purrs. People are amazed when it’s running. Big rubber feet also help prevent transmitting vibration to whatever it’s sitting on, so no more vibrating boards.
B) Over-built compressor compared to tank size – so cycle times are very short – if using light-duty tools, it doesn’t run much anyway. Also runs way more cool than others – I’ll save those sear lines for my steak on the grill – not my forearm.
C) No leaks – holds its air pressure seemingly forever when turned off (not that you shouldn’t release pressure when done using it).
D) The air filter is a miniature version of an old-time car air filter. For a unit that’s going to be sitting on the ground amidst swirling construction dust, this is a big plus.
E) It does indeed weigh in, but at least the design is very compact. The frame wraps around and protects most of the important stuff, so there are no lines, wires, etc. waiting to be snagged. The glaring exception is the air filter hanging off the side – I can see this part’s going to be replaced at some point when I throw it in a truck bed. No problem for shop use though.
Be forwarned – Makita’s packaging designers always seem to get it 90% right. In this case, the air filter is just thrown in loose inside the box – mine broke one of the gauge glasses. If pressed, their warrantee dept. will send out small parts, but it’s a PITA to get a product this good only to have to fix it right out of the box. Also – pay attention to the “break-in” procedure – run it for @30 minutes with no load, open petcock, to seat the rings.
