HPDMC Compressor Reviews 20

After using air compressors for over 5 years -including some very expensive brands - I can confidently say this HPDMC oil-free unit outperforms them all.
It's the perfect size for my 2-car garage: compact but powerful enough for finish nailing, tire inflation, and occasional spray painting. The noise level is impressively low (I can actually have a conversation while it's running!), and I love that it has two switches: a main power cutoff plus a separate on/off toggle for daily use.
Setup was plug-and-play, and the seller answered all my technical questions fast and professionally. I liked it so much that I've already ordered a second unit as a backup -that's how much I trust it.

I've been using 13HP Gasoline Power Air Compressor on construction sites for the past two months, and it's been a game-changer for our mobile spray foam and framing crew. What really sold me was the ASME-certified 30-gallon tank-safety matters when you're working in high-pressure environments, and this unit gives peace of mind. The two-stage, air-and-oil-cooled design keeps it running cool even during long shifts, anddespite being a commercial-grade machine, it's surprisingly quiet compared to other gas compressors I've used. The engine starts reliably every time, even in cold morning conditions, and the lightweight connecting rods seem to reduce vibration significantly-my tools last longer now. It's perfect for jobs that require mobility; we tow it between sites without issue. I originally compared similar models on Amazon, but HPDMC's team answered all my technical questions within hours-including voltage compatibility and NPT fitting details-which gave me confidence to buy direct. Highly recommend!

No fuss. It’s gas-powered, yeah, but it runs clean — no weird smoke or oily smell, which I was kinda worried about since we’re handling food. We keep it a few yards away from the main area, downwind, and it’s been totally fine.

Oh, and shoutout to the customer service team — called ‘em with a question about grounding and they didn’t just read from a script. Guy explained everything step by step, sent over a PDF, even followed up the next day to make sure we were good. Felt like they actually cared.

Grabbed this 6.5HP KOHLER gas compressor back on Sept 8 around 6:44 PM—shipped out to Richfield, Utah, and it showed up in about a week. We use it over at our little meat processing spot during hunting season.

After this purchase, HPDMC is my new go-to for air compressors. The quality is top-notch, prices are fair, and the service was excellent. Highly recommend.

I took the gamble and went for one of the used "Open Box" gas compressors and I'm glad I did. The machine works wonderfully and I saved a lot of money. It's a fantastic value.

The description for the used compressor I bought was very accurate. It noted minor cosmetic blemishes, and that's exactly how it arrived. It functions perfectly. I appreciate the honesty.

I was surprised at how fast the compressor made its way. The fact that they have a DC near me is why I had my order in a few days. Well packaged and arrived in pristine condition.

Swapping out my dated pancake compressor for a proper version with a rotary screw from HPDMC has revolutionized my at-home automotive and motorcycle projects. Power and consistency are night and day.

You can really tell this is heavy duty equipment. Our new 15hp rotary compressor is commercial grade solid steel and much, much quieter than our old version. Quality is in the details.

The people over at the sales team at HPDMC were just very well informed. Instead of only upselling me, they guided me to the exact right model for my shop. Awesome experience while I was working here.

I picked a model off their “Hot Products” list, and instantly it has proved worthy of the name. What you won’t hear is that it is popular for good reason… it works!

I use a portable gas powered compressor for my mobile repair business. It’s light enough to be mobile, starts up without fail and has enough oomph for all my air tools on the road. Great build quality, very well pleased.

We bought the 20hp Rotary Screw compressor by HPDMC for our auto shop and it is extremely reliable. It not once has failed us to provide a steady air pressure for our tools. A great investment that has increased our productivity.

I did months of research before landing on this 20HP unit. It's easily comparable to the bigger brands but without the inflated price. We use it in our cabinet-making business, and it supports multiple routers and air tools at once. The touch-screen control panel is intuitive, and I appreciate the automatic alerts for maintenance. Very happy with this purchase.

I operate a mobile tire repair business, and this gasoline-powered piston compressor has been a lifesaver. No need for electrical hookup, and it runs long enough to get through multiple jobs. It’s rugged, handles all weather conditions, and starts reliably even after sitting for a week. HPDMC really nailed it with portability and build quality.

When we scaled up our operations, this 20HP unit was our first major equipment upgrade. HPDMC delivered fast, and their setup manual was super beginner-friendly. We paired it with a refrigerated dryer, and the entire system performs flawlessly. Definitely recommend it to any small business going through growth—it’s industrial-grade without the industrial headache.

Customer support is reliable, supportive.The unit itself is excellent—quiet, energy efficient, and reliable—but I am impressed with HPDMC’s customer service. When we had a question about oil change intervals, they responded within the same day with video guidance. It’s rare to find this level of post-sale support anymore. Highly recommend for peace of mind.

VSD control is a money-saver! The 20HP unit with variable speed drive (VSD) has saved us so much on electricity. It ramps up only when needed, unlike our old fixed-speed unit that ran constantly. You can literally see the efficiency gains on your electric bill after a month. If you're worried about long-term cost, go with VSD—it pays for itself.
