Overview
The Makita MAC2400 is an electric powered air compressor with a 4.2 gallon tank, built around Makita's Big Bore piston pump design for job site use. It runs on standard 120 volt power, making it suited to garage or shop outlets rather than industrial lines.
Makita markets this line as a Big Bore compressor, referring to a larger piston bore that fills the tank faster than smaller pumps at a similar horsepower. The 4.2 gallon tank is a mid size for job site compressors, enough to run finish nailers and staplers for stretches without constant motor cycling, though it will empty faster than a larger shop tank under continuous air tool use like a die grinder.
- 4.2 gallon tank capacity
- 120 volt electric power source
- Makita Big Bore pump design
- Sized for job site portability
Who it's for
Contractors and DIYers running nail guns, staplers or other intermittent air tools on job sites or in a home shop. Less suited to shops needing continuous high volume air for spray painting or sanders.
Pros and cons
- Big Bore pump refills the tank quickly
- Standard 120 volt power works from any shop outlet
- 4.2 gallon tank suits intermittent nailer and stapler use
- Tank size limits continuous high demand tool use
- Corded electric power means staying near an outlet
Performance notes
The Big Bore pump design fills the 4.2 gallon tank quickly compared with smaller pumps, so recovery time between bursts of nailer use stays short. A 4.2 gallon tank still limits how long you can run continuous draw tools before the motor has to cycle back on.
