How much compressed air is really required in a small to medium size home woodworking shop?
I know some guys have the big standup air compressor’s with 5hp motors and 60 gal storage tanks but home much of that is overkill if all your useing is pin nailer and brad nailer and a blow gun for cleanup?

Would a small 2 hp unit with a 4 gallon tank be enough for the pin and brad nailers if your not doing any spraying for your finish work?
I think if I decided to any spraying I would go with one of the turbine units anyway so the extra air from the compressor would not be required.

I know that the HVLP spray guns require a very large cfm rateing but most of the nailers only use 2 to 5 cfm unless your talking about a framing nailer or roofing nailer for counstruction work , but all I am talking about is small wood shop where you are useing electric sanders and just a pin nailer and brad nailer as your air powered tools.

I had a smaller unit and only upgraded when I bought sanders. The guys who installed my floors used a tiny little DeWalt for their big framing nailers. You don’t need much for nailers but sanders, some disc grinders, and other tools can really eat air. My orbital sander takes something like 10CFM which is the max my big compressor can put out. However, I’ve got $10 brad nailers that have worked without a single problem for 10 years. Go air!

I have a small DeWalt (2 gallon, I think) that I use for my nail guns. I use a turbine HVLP sprayer. This I all I need.

I think if I had a larger workshop with a finishing room, I’d want something bigger…but for right now I see no need for anything beyond my very portable unit at present.

I already had the 30gal standup so I could not say what the minimum is, though I am glad I have as much air as I have. Sometimes I just HAVE to get out the air and spray dust toward the open door, sweep, air, sweep, and just get a good cleaning(wearing a dust mask). My other uses include impact tools, tire inflation, etc.

That being said, IMO buy as much as you can afford. You WILL find uses for it.

Small is better and potentially quieter if only brad nailers and even mini HVLP are used. But if air tools are in the future, go larger.

I love my little Dewalt D55141R that I have wall mounted. I got it from CPO and it is factory refurbed. Not a bit of trouble and use it every day.

Specs: 0.6 HP 1.8 CFM delivered at 100 PSI, 2 gallon tank and 150 maximum PSI, Low 71 dBA allows for quieter operation,Roll cage and control panel provide protection to key compressor components, Low 8.0 AMP draw motor provides easy start-up and reduces breaker tipping, Lightweight (only 30 lbs.), thin (10.5”) and compact design is easy to carry and store, Ball valve drain, Dual quick couplers to easily support two nailers,
High flow regulator for increased performance.

i have a Bostich CAP20002.8 CFM @ 90 PSI with 150 max, large 6 gallon tank. for general use ( ie, nailing and stapling) its plenty enough. for shop cleaning it does a fair shop but sometimes i have to wait a couple seconds for the pressure to build up. It kept up while using a gravity feed paint sprayer but it never shut off. if your gonna be spraying alot i would recommend something larger or a turbine setup

Yep, that’s the one I have, David. You can’t really spray with it, at least not with my regular spray guns, but it’s good for nailing and filling up the tires. It won’t keep an air chisel up to speed either. Haven’t tried an air sander, but I’d venture to say you’d need a bigger compressor for that.

I have a Bostitch CAP1516 (CPACK 270) ... has a small (1.6 gallon) tank, but can go up to 125 psi.

It is fine for pin/brad nailers and the like, but it just can’t handle sanders, sprayers, etc. I like it … it fits neatly in a ;garage’ in the end of my workbench, is relatively quiet, and regenerates quickly.

I have the pancake style little Porter Cable from Lowe’s Depot (about $100) and it keeps up fine with the nailers and generic blowing off tasks. Plenty small but really loud. If that Dewalt above is really that quiet I would steer clear of mine!

I have a 12Gal under the assembly table with a hose reel. I use this the most. I’ve had this compressor over 20 years and used it to put a roof on my house and my father in laws. If you wet sand metal, you’ll find the sanders come in handy. I also have air nibblers and impact wrenches. They are also good for small grinders and cutters.

I would go for a nice mid sized compressor because they don’t cycle as much and are easy to fit with regulators and dryers. I do have a pancake compressor I bought to help remodel my daughter’s house. Came in handy to lay the wood floor in our house but don’t use it much in the shop. I don’t like that small hose that came with it and it can’t blow the dust off the floor and my clothes like the bigger one.

IMHO, get one that has at least 10 gal tank or better, get a quality one and you’ll have it for a long time.

I have a 33 gal upright Craftsman OIL LESS compressor and its LOUD!! I also have a small Craftsman 2hp, I think, and its cool. The smaller unit is perfect for driving small nailers, 18ga, 23ga etc. Its also light and easily portable. Sears usually has a scratch and dent store in most locations, separate from the main store. I picked mine up there and it was a refurb…...$35

FWIW, the best thing about my 33 gal upright is the capacity. You can do a lot without the compressor having to kick in and recharge. IMO, all compressors are loud unless you keep them in a separate room and run an airline through a wall.

A small 4 gallon or 6 gallon compressor is fine for the air nailers.
I have the 33 gallon like mike, it is convient to not have it turn
on all the time. You might want to consider what your air needs
might be in 5 years…or not

I’ve got two. A small portable unit for use with nail guns. Great for taking around the house and doing projects. I have a Large Porter Cable upright in the shop for other use. This was one of those tools that I wondered how I ever lived without it once I got it in the shop.

For what you’ve stated that would be your requirement for your shop. Your only requirement is limited to the amount of CMF’s need to run a tool. I went to the 5 HP 60 gal. model because some of my air tools are air hogs and require higher CMF ratings. One suggestion I would make is to buy the oil filled compressor over the oil less compressor. The oil filled runs quieter than the oil less models do.
