found in MAC2400's description:From the Manufacturer
The new MAC2400 - Twin Stack aircompressor by Makita is blowing away the competition.3 amps to operate, a lower 1720 RPM rating and a heavy duty Intake Air Filter system like no other, its easy to see how this unit will out last and outperform everyone else. Large automotive style industrial air filter for increased air intake and greater efficiency.
found in MAC2400's reviews: Excellent AirCompressor - I had previously made the LOUD mistake of getting a "maintenance-free" aircompressor. Although not silent, this aircompressor is MUCH more tolerable. This compressor is also of good quality and very sturdy (heavy) construction.
20 by 15.6 by 16.5; 71 pounds; 5-year warranty on electrical components Includes manual Durable cast iron 5 cfm at 100 psi; quiet 74 dB; 2-cylinder in-line design 13-1/2 amp, 2-horsepower, 4-gallon, oil-free twin hot dog compressor
found in T-2820ST's description:From the Manufacturer
At (74-decibels) the Thomas T-2820ST is the quietest 2 HP contractor grade compressor on the market. Delivering 5 cfm at 100 psi it is also the highest output 2 HP compressor available. Often called "The Cadillac of Portables" it sets the standard on what 2 HP compressors should be.
found in T-2820ST's reviews: This is a keeper! - this is a great compressor. I've used it for air guns, various types of light and heavy duty nail guns, and shop tools. Very quiet compared to other compressors of the same size, but compressors will never be mistaken for a 'silent' partner.
