The DEWALT 27 Gallon Vertical Air Compressor is a 1.7 HP oil-free portable air tank built for home improvement projects, garage workshops, and light professional work. It delivers 5.1 SCFM at 90 PSI and 6.8 SCFM at 40 PSI, giving you enough airflow to run nailers, staplers, impact wrenches, and inflation tools without constant cycling. Its low-volt easy start motor helps it start reliably even on circuits that dip when other tools are running.
Because it runs without pump oil, maintenance is simpler and there’s no risk of oil mist in your air lines. The vertical tank saves floor space while still giving you 27 gallons of capacity, so you can work longer between cycles. At 78 dBA, it’s quiet enough for a detached garage or shed without needing ear protection for short jobs (though we still recommend hearing protection for extended use).
The integrated handle and wheels (where applicable) make it easy to move around the shop. Its vertical profile tucks into corners and tight spaces where a horizontal tank wouldn’t fit.
To keep your compressor running reliably, check the pressure switch and regulator before use. If the tank won’t build pressure, inspect the check valve, pressure switch, and any leaks in the hoses or fittings. A complete DEWALT 27 gallon compressor parts list is available through our support team, so you can find the right replacement parts fast.
This DEWALT 27 gallon compressor ships ready to use. Check the manual for included accessories and assembly steps.

MPN: 27 Gallon Vertical Air Compressor
With a 27-gallon tank, your compressor draws less often, so tools get a steadier supply of air. That means less motor wear and more consistent fastening and inflation. Unlike smaller pancake compressors, this vertical unit is suited for running multiple tools in a row or using a HVLP spray gun for short sessions.
Start by closing the drain valve and setting the regulator. Turn the power on and let the tank fill to the cut-out pressure. Then adjust the regulator to match your tool's requirement. Always drain the tank each evening to extend tank life.
Check the check valve, pressure switch, and air intake filter. Look for leaks in hoses and fittings with soapy water. Contact our support team for more diagnostic help.
Yes. Contact Workbench World support and we can provide the manufacturer's parts breakdown and help you order replacement parts.
Disconnect power, drain the tank, and remove the pressure switch cover. Note the wiring before disconnecting, then install the new switch and reconnect. If you're unsure, contact a qualified technician.
Yes, the pump is oil-free, so you won't need to check or change pump oil. Just keep the intake filter clean and drain the tank regularly.
Good compressor, quiet enough for my old ears.
I replaced an old tank with this and it's been great. It runs a framing nailer and impact wrench without waiting too long. The low volt start actually worked in my shed with a long extension cord.
I'm a home DIYer and this is my first big compressor. It's heavy but on wheels so that helps. It fills the tank fast and powers my nailer. However, it is louder than I expected even for an oil-free unit. Also, the instruction manual wasn't the clearest. It does the job, but I wish I'd bought a model that was a bit quieter.
Solid compressor, no issues.
I've had many compressors over the years. This is one of the better ones. It starts in the cold garage easily.
I'm a newbie at using compressors, but this one was easy enough to figure out. It aired my tires and ran my nailer fine.
I run a small garage and this compressor handles everything from impact wrenches to a sandblasting cabinet, though it does cycle a lot on the cabinet. The 5.1 SCFM at 90 psi is honest. The vertical tank takes up less floor space, which is why I chose it. The low-voltage start is handy on older wiring. The only drawback is the noise level, but it's not worse than other oil-free units. Overall, a dependable compressor for the money.
My husband uses this to power his spray gun and it does a fine job. The wheels make it easy to move around. It didn't need any assembly beyond attaching the handles.
Works like it should.
I bought this for my garage art studio. Actually, I use it for cleaning with a blow gun and occasionally inflating. It's much bigger than I needed, but future-proof. The tank holds air well and doesn't drop quickly.
