Product description

– The Makita MAC2400 is a member of the big bore line of air compressors. It features a cast iron pump with a big bore cylinder and piston. This allows the pump to run at a low RPM rating while still offering fast recovery time. The cast iron cylinder holds up well to high intensity jobs and can power two nail guns simultaneously.

The pump is driven by a 2.5 horsepower motor. The motor features low Amp draw which reduces chances of tripped circuit breakers. The low amp draw also protects the motor from sudden voltage drops which can cause damage.

– The Makita MAC2400’s pump is oil lubricated to ensure that it runs smoothly. The oil also acts as a coolant helping to keep the pump in peak working condition even after repeated use. This air compressor’s pump also features a large air filter which maximizes air intake which improves the units overall efficiency.

– One design feature that stands out from other air compressors is the 4.2 gallon twin stacked tanks. This design feature serves two purposes. First, it ensures that the air compressor features a compact highly portable unit. Measuring 20 X 18 X 18.8 inches, the Makita MAC2400 air compressor is easy to store away even in small spaces. The second purpose served by the 4.2 gallon twin stacked tanks is to sustain consistent pressure output. Its operating pressure is rated at 130 PSI with an output of 4.8 CFM at 40 PSI and 4.2 CFM at 90 PSI. This makes it an ideal air compressor for running high pressure output air tools.

The low RPM operation is complemented by an oil lubricated pump to ensure that this air compressor operates with low noise output. The air compressor’s body is supported by rubber feet which minimize vibrations.

– The Makita MAC2400 big bore 2.5 hp air compressor features an easily accessible oil drain. It also features an oil sight glass which enables you to know when an oil change is due. The built in tank drain valve allows you to easily drain off accumulated water.

– For easy transportation, this air compressor features a roll bar handle which double up as protection for the on board components. Each air compressor comes with oil and a 1/4-inch universal quick coupler.
