Makita Corded Electric Air Compressor MAC2400 4.2 Gallon Tank (2.5 HP Big Bore Cast Iron Pump 4.2 CFM 90 PSI 130 Max Dual Framing Nailer Power)

Makita MAC2400 2.5 HP Big Bore 4.2-Gallon Twin-Stack Electric Air Compressor

The Makita MAC2400 2.5 HP Big Bore 4.2-Gallon Twin-Stack Electric Air Compressor delivers 4.2 CFM at 90 PSI and achieves a 130 PSI maximum working pressure to reliably run two pneumatic framing or finish nailers simultaneously. Powered by a low-RPM 4-pole motor operating at just 1,730 RPM and 79 dB noise output, this heavy-duty compressor pairs a cast iron Big Bore cylinder and piston assembly with an oil-lubricated pump to maximize recovery speeds, reduce component wear, and prevent jobsite breaker trips through low AMP draw. Encased in a rugged steel roll-cage frame with copper-finned discharge heat dissipation tubing and dual universal quick couplers, it supplies stable pneumatic power for demanding residential construction and trim carpentry.

Best Used For:

• Concurrent Two-Gun Framing: Operating two pneumatic framing or sheathing nailers simultaneously using dual 1/4-inch quick connects backed by 4.2 CFM at 90 PSI output.
• Interior Trim & Finish Carpentry: Supplying quiet, continuous 79 dB air volume for 15-gauge finish nailers, 18-gauge brad guns, and narrow crown staplers without disruptive jobsite noise.
• Low-Voltage Residential Remodels: Starting up smoothly on shared residential 15A circuits without tripping breakers due to low electrical AMP draw.

Key Performance & Safety Features

• Big Bore Cast Iron Cylinder: Increased cylinder bore and stroke provides greater air compression, faster pressure recovery times, and extended pump life.
• Low-RPM 4-Pole Motor: Runs at 1,730 RPM to cut operating sound down to 79 dB, drastically reducing mechanical wear compared to high-speed alternative units.
• Twin-Stacked 4.2-Gallon Tank: Compact dual-tank architecture sustains 130 PSI maximum pressure for balanced air delivery across multi-tool setups.
• Low AMP Electrical Draw: Engineered motor windings minimize voltage drops and eliminate nuisance breaker tripping at startup.
• Copper Finned Discharge Tubing: Dissipates heat rapidly between the pump and tank, minimizing internal condensation and water accumulation.
• Heavy-Duty Roll-Cage Handle: Protects vital pump, motor, and gauge assemblies against rough handling, tip-overs, and jobsite debris.

Technical Specifications

Pro-Tip: Check the front oil sight glass before every workday to keep the oil level centered; running the Big Bore cast iron pump at proper lubrication levels preserves internal tolerances and maintains quiet 79 dB operation.
