Customer Questions & Answers

Is the compressor powered by an electric motor and if so how large and the amperage?

Asked by: albert
Electric, 2HP rated @ 14 amp draw. no breaker trip issue even when running my saws. I never use a extension cord with my compressors. better to use extra hose

How many tools can connect at once?

From the picture it looks like the compressor only has one connector for connecting an air hose. I need to be able to run at least two nail guns at once. Can this be done? Maybe it requires purchasing an additional adapter?
Asked by: Darren
You can purchase a "T" or individual parts and make one to allow connection of two hoses at once. Ascertain that the fittings are the same configuration as several are available. Do not over-draw air; the compressor needs to be able to catch up and cool down between charges.

Specs say decibel rating has not been tested. ??? How loud is it? If it's quiet I'll buy one.

Asked by: redharmony
you cant stand next to it and talk on the phone ,California compressor offers a super quiet 2hp compressor for around $350. noise isn't an issue with me and I purchased on sale with oscillating tool for $169 from $300 couldn't beat it. California is dual pump at 1750 RPM/ standard is single pump @ 3400 RPN thus decibel and vibration reduction

Customer Reviews

4 Gal. Twin Stack Air Compressor and Pneumatic JobMax Multi-Tool Starter Kit is rated 4.2 out of 5 by 11.
Rated 4 out of 5 by from Good quality for the price. I just opened everything started it for the first time. The base must not be level since one side is higher than the other three pads. This causes the compressor to dance across the floor when running.
