Overview
The Makita MAC320Q sits at the top of the price range in this comparison at $384, and it backs that price with a 4.7-star rating from 569 owners. That is the joint-highest rating in this batch alongside the Master TC-326T and the Makita DMP180ZX, confirming that buyers who choose the MAC320Q come away highly satisfied. Published dimensions are 12 inches by 12 inches by 12 inches, and the listed weight of 25.79 kilograms places it firmly in the category of shop-resident compressors rather than carry-around tools.
The 3-gallon tank is the largest in this comparison among corded tank units, supported by 120-volt corded electric power. This combination suits sustained finish nailing, trimwork, light spraying, and air tool use where a 1 to 2 gallon tank would cycle too frequently. For production-level finish carpentry or trim crews, the larger tank means fewer interruptions mid-board.
Buyers comparing the MAC320Q to the MAC100Q should note the $105 premium buys a 3 to 1 increase in tank size but comes with a significant weight increase. For users who keep a compressor in one place, the MAC320Q is the more capable long-term option in the Makita corded lineup.
Pros
- 4.7-star rating from 569 owners is among the highest in this comparison set
- 3-gallon tank is the largest among the corded models reviewed, supporting sustained air tool use
- 120V corded operation provides reliable, battery-independent performance
- Makita professional build quality backed by a meaningful review base
- 12 x 12 x 12-inch footprint is compact for a 3-gallon unit
Cons
- $384 is the highest price in this comparison; value depends on professional use frequency
- 25.79-kilogram listed weight makes it a stationary shop tool, not a portable carry-around option
- 569 reviews is a smaller base than the MAC100Q at 1,500, though per-owner satisfaction is high

Performance notes
The Makita MAC320Q runs at 120 volts corded electric with a 3-gallon tank and dimensions of 12 x 12 x 12 inches. The listed weight of 25.79 kilograms is the primary constraint for portability. No CFM or PSI output is published in the listing specs, so detailed airflow delivery figures require consulting the full Makita product specification sheet. The 3-gallon tank provides meaningfully more sustained airflow than 1-gallon or 2-gallon alternatives, reducing compressor cycling during continuous nail gun or air tool use.
What buyers say
Owners describe the MAC320Q as a dependable, professional-grade compressor that performs consistently for demanding shop and job site tasks. The 4.7-star average across 569 reviews reflects strong per-owner satisfaction. The most consistent praise centers on build durability and reliable air delivery. Criticism at this price point primarily targets the weight and the investment required relative to budget corded alternatives with similar tank sizes.

Frequently asked questions
How heavy is 25.79 kilograms in pounds?
25.79 kilograms converts to approximately 56.9 pounds. That is substantially heavier than the 1-gallon Makita MAC100Q at 27.6 pounds, and reflects the MAC320Q's positioning as a stationary or cart-mounted shop compressor rather than a carry-to-the-job unit.
Is the Makita MAC320Q better than the MAC100Q for finish carpentry?
Based on specs, the MAC320Q's 3-gallon tank will cycle less frequently during sustained finish nailing than the MAC100Q's 1-gallon tank, making it the better fit for production finish work. The MAC100Q is more portable at 27.6 pounds and $105 less, making it preferable when moving between job sites frequently.
