ASIN: B084LZPF49Model: MAC320QCategory: Air Compressors
Overview
Corded, 120-volt and built around a 3-gallon tank, the Makita MAC320Q packs a compressor into a roughly foot-cube frame that weighs 25.79 kilograms, about 12 by 12 by 12 inches overall.
This is Makita's smaller MAC-series tank compressor, corded and AC powered rather than battery driven, which suits stationary use at a bench or in a shop rather than moving between sites. The 3-gallon tank puts it closer to finish-nailer and stapler support than continuous-duty air tools that drain a tank quickly. Its near-cube dimensions make it easier to tuck under a bench than a long horizontal tank compressor.
- Tank: 3 gallons
- Power: 120V corded electric
- Weight: 25.79 kg (about 57 lb)
- Footprint: about 12 x 12 x 12 in
Who it's for
Fits a homeowner or trim carpenter who needs air for finish nailing, stapling or occasional inflation at a fixed location with an outlet nearby. Not suited to a crew running a framing nailer or sander that needs sustained high CFM, where a larger tank would be a better match.
Pros and cons
- Compact near-cube footprint for its tank size
- 3-gallon tank suits finish nailers and staplers
- 4.7 rating across 569 buyers
- Corded design needs an outlet nearby
- Heavy at roughly 57 pounds for repeated carrying
- Tank size limits continuous high-draw tools
Performance notes
A 3-gallon tank recovers relatively quickly between bursts, which suits trigger-pull tools like finish nailers that draw air in short spikes rather than tools that pull continuously. Being corded rather than gas or battery powered, it needs a 120-volt outlet within reach, and the 25.79 kilogram weight means it is meant to be set down and left rather than carried around a site all day.
