- Ridgid Twin-Stack Portable Compressor, OF45150
- Brand: Ridgid | Category: Compressors

I have had this oil-free compressor for several years and have used it in conjunction with my Ridgid and Campbell-Hausfeld framing nailers to add timbering to my attic trusses, build a fancy coffered ceiling in my garage, and add additional nails to the siding on my house. I have also used it to power finishing and brad nailers for assorted projects.
The thing works just fine. The calibration is perfect and I appreciate not having to worry about oil in the compressor section. It weighs 70 pounds, which makes it kind of awkward to carry around (note the single hand hold in the photo, which makes me think it was designed to be carried by Popeye), but when I did the work on my house I simply left it inside my shop out back and ran hoses of appropriate length (up to 200 feet) to the project. The one exception was the garage-ceiling project, where I had to keep changing from the framing nailer, to the brad nailer, to a palm nailer, and back. It was good to have the unit closeby for those multiple disconnect situations.
I cannot think of a thing I would change, except that maybe it would be a bit easier to live with if it had big wheels attached. Come to think of it, Ridgid now has one with wheels, but I think it comes with an oil-lubed compressor.

I drag this compressor into and out of houses every time I do an install. That 70 lbs makes me feel every year, but I need a compressor large enough to run my spray gun. And this noisy heavy bastard sure does the job.

Next time you need to swap devices back and forth, try the following:
1.) Add a manifold or splitter to split the air line in two.
2.) Set the air line pressure at the compressor to the higher requirement
3.) Install a second regulator at the back of the tool that needs the lower pressure
You can accomplish a similar end with only the regulator and some extra quick connectors.
Everything you need is in the same aisle at Home Depot where you found the compressor. My stuff is all quick connectored for easy recongifuration. The extra regulator is very handy any time you need to be working away from the compressor and don’t feel like running back and forth to change pressures.

Just an observation if I may – that thing is a Campbell-Haus compressor with a Rigid label; why on earth would you run dual hoses and another regulator etc when the operating range of all those guns is common and set it mid range, around 95 lbs. I see no issue with an oiled compressor – it is FAR less noisy and I have never seen an oil problem. Use quick disconnects for the varied tools. To each his own.

“Just an observation if I may – that thing is a Campbell-Haus compressor with a Rigid label; why on earth would you run dual hoses and another regulator etc when the operating range of all those guns is common and set it mid range, around 95 lbs.”
My unit is an oil-lube Porter Cable, but as I suggested the extra ($20) regulator… The operating range of several of my guns is not as common as I’d like.
- When stain grade trimming with small detail moldings, my 18 gauge brad nailer can not be dialed back enough when the air line is set for my 15 and 16 ga. guns, forget about the 23 ga. I can get usually away with the same pressures in paint grade work.
- When I install hardwood flooring, the floor gun needs a much different pressure than the 15 ga. angled gun I use in corners and edges, and the 18 ga. stapler used to tack down rosin paper.
- When I use my “Critter” touch-up gun, the extra regulator allows fine pressure tuning at the gun.
- When my compressor is two floors down, I set the air line for max pressure and adjust at the site.
- In my shop, my 23 ga. pinner uses ~ 20 less PSI than my 18 ga. stapler and brad nailer. I’ll usually use them on the same hose, with the second regulator on the pinner.
Every air powered item I have is equipped with Milton quick connects and even still, I find an extra $20 hose and $20 dial regulator to be preferable than swapping hoses.
It works for me… <g>
