Customer Questions & Answers

Why is this smaller tank size more expensive than the 6gal. Size? Does it have to do with the twin tank? Is it better?

Asked by: Emily
The shape of the twin-tank unit is more like a box, and easier to move and handle. The tradeoff is that more metal and more welds are required, so it's going to be more expensive.

what size compressor do I need to operate a framing gun that requires 12.85 scfm 100 fasteners per min@90psi

I asked this question before and got the usual read the specs which I didn't have because I couldn't find them in the specs listed on homedepots.listing for this product on line . SO AGAIN HOW MANY cfm, s do I need to safely operate this freeman framing gun that requires 12.85 scfm with 100 fasteners per minute @ 90 psi. I own a 6 gallon porter gable pancake that produces 2.6 cfm @ 90 lbs max 135lbs . Is this sufficient and don't tell me to calculate scfms to cfms at 60 degrees . The high today was minus 1 below !!! I now have recleved the guns and want to use them but don't want to void the warranty by using the wrong compressor !
Asked by: aboutime
The basic range for this kind of nailer is 4 to 6 CFM. Since your not going to operate the tool any where near "standard" conditions you can reduce the SCFM by a factor of 2 or 3. Your 6 gallon pancake will probably not work, suggest using something a little bigger around 2HP 10+ gallon compressor.

Will this thing run an Impact wrench?

Asked by: Coalescterol
I would say yes, although I have not tried it my self. It easily reaches the pressure you would normally run an impact wrench at, 80-100 psi. It recovers very quickly after use. If you are a DIY guy taking the tires off your truck, I believe you would have no problems. If you are a pro and using it continuously you may want something with a higher storage volume.

4.6 Gal. 1 HP Ultra Quiet and Oil-Free Aluminum Twin Tank Air Compressor is rated 4.7 out of 5 by 77.
Rated 5 out of 5 by from Best air compressor I've ever had. I like airbrushing scale models and sometimes I work past midnight this air compressor is quiet enough that it dosen't wake the wife and that would be bad, and I like the portability as I can take it with me to hobby meets and it wouldn't cause any disturbance to other modelers. thank you for making such a great product and I would advise anyone looking for a quiet air compressor to look into this 4610A air compressor from California Air Tools.

Rated 5 out of 5 by from Exactly as Advertised - Ultra Quiet and Good Performance I hate pollution including noise pollution and this unit proves the point that air compressors don't need to be noisy (and irritating to everyone within 50 ft - even when used outside). All of the components on this unit appear to be of expected quality and work well. I've used it for a few weeks with basic uses - car/truck tire inflation, small nailers and general hobby use and the unit is fully satisfactory. I expected slower performance but the time to fill tanks to maximum is quick - and the cycle time is similar to the many noisy models I've used in the past. There are No compromises in performance with this unit. My only suggestion for improvement is that the final assembly leaves several items relatively exposed and subject to potential damage. The air filter is an add-on and the various valves and switches are unprotected and vulnerable. If used daily on a job site by different users - I see damage occurring to some components. Also, I prefer to hang most of my small equipment on wall-hooks and better packaging (complete wrap around frame) and bigger handles are my only areas for improvements here.

Rated 5 out of 5 by from Extremely Quiet, Powerful I had gone years using a cheap compressor for around the house jobs, but one day I couldn't take the noise anymore and I found this unit. I was skeptical at first, but take it from me, this unit is as promised, extremely quiet, well built, dual connections. This would be great for interior carpenters as well.

Rated 5 out of 5 by from Don't for get to screw in the air filter. Ran compressor for first time and noticed it was quieter than a pancake compressor but not as quiet as the comparison video. Then I noticed that the air filter wasn't screwed on and the manual doesn't mention anything about this step. Ran compressor again with filter and it's amazing how quiet it is. I would compare it to when my fridge compressor kicks in. Haven't used it much but I would say this is a keeper. Plus it's light and portable. Also, the picture doesn't show it but mine has a ball drain valve instead of a screw type.

Rated 4 out of 5 by from Lightweight and quiet This is the first twin tank compressor I have ever owned that doesn't throw my back out when lifting in and out of my work vehicle. It is also the quietest twin tank oilless that I have ever heard - it makes about as much noise as a refrigerator. Although far superior to my Emglo and Senco twins, I am disappointed in the air delivery running my Hitachi framing nailer as it is unable to keep up with rapid fire for sheathing. A major design flaw, in my opinion, is the power switch location. The lever is right near the relief pin so the pin frequently gets inadvertently pulled while turning on or off. On the upside, the quick-release tank drain makes it easy to bleed out condensation at the end of the day.

Rated 4 out of 5 by from I bought this as a replacement for one that was stolen I am impressed with the quietness of operation. It also seems to have a very quick recovery time when refilling the tank(s) to the correct pressure.

Rated 5 out of 5 by from Quiet, yet powerful This unit has been well engineered. It is unbelievably quiet! I have used it with a brad driver, a finish driver and nail framer and it has worked flawlessly.
Date published: 2013-03-19
Rated 5 out of 5 by from Very quiet compressor I installed pneumatic door closers for handi capped bathrooms so I needed to have air pressure constantly available. The old Pancake compressor I used for nail guns worked well but shocked me everytime it started. The CA is quiet and well made. As usual, you get what you pay for. If you need a quiet compressor this one is a candidate. It is also very light.
