DeWalt 7.5-HP 80-Gallon Two-Stage Air Compressor

As a seasoned tool enthusiast, I've had the opportunity to work with numerous air compressors over the years. Recently, I got my hands on the DeWalt 7.5-HP 80-Gallon Two-Stage Air Compressor, model DXCMV7518075, and I must say, it has left quite an impression. This compressor is built for heavy-duty use, and it certainly lives up to its reputation.

First off, let's talk about the build quality. The 80-gallon ASME certified tank is a beast. It's robust and designed to handle high pressure, with a maximum operating pressure of 175 PSI. The tank's vertical orientation is a smart design choice, saving valuable floor space in my workshop. At 623 pounds, it's not exactly lightweight, but the heft is a testament to its sturdy construction.

The heart of this compressor is its 7.5 HP electric motor. This single-phase motor operates at 230 volts and is paired with a two-stage reciprocating pump. The combination ensures a reliable and consistent air supply. The pump speed of 1725 RPM is relatively low, which is beneficial for reducing wear and tear, ultimately extending the life of the unit.

One feature that stands out is the extra capacity oil reservoir. This design helps maintain lower oil temperatures, which is crucial for the longevity of the compressor. An oil-lubricated pump might require a bit more maintenance than an oil-free model, but the trade-off is worth it for the increased durability and performance.

Noise is always a concern with air compressors, especially in a busy workshop. The DeWalt compressor operates at 84 dBA, which is quieter than many of its competitors. While it's not whisper-quiet, it's manageable and doesn't disrupt the workflow.

Setting up the compressor was straightforward. It comes pre-wired, so all I had to do was connect it to the magnetic starter and run the wire to my power source. Once powered up, the compressor roared to life, and I followed the break-in protocol as recommended. The initial performance was impressive, with the compressor quickly reaching its maximum pressure.

In terms of performance, this compressor is a monster. It delivers 22.1 CFM at 100 PSI and 21.2 CFM at 175 PSI, which is more than sufficient for most heavy-duty applications. Whether I'm using it for sandblasting, painting, or running pneumatic tools, the DeWalt compressor keeps up without breaking a sweat. The air pump is efficient, and the cast iron construction ensures it's built to last.

One thing to note is that the pump does generate a fair amount of heat, which can introduce moisture into the system. To address this, I recommend investing in an automatic drain valve, a good air regulator, and an aftercooler with a water coalescer. These additions will help maintain a dry air supply and prevent moisture-related issues.

During my time using this compressor, I've found it to be incredibly reliable. It starts up without hesitation, and the pressure shut-off valve works flawlessly. The Baldor motor is a standout feature, known for its durability and performance. It's clear that DeWalt has put a lot of thought into the design and construction of this unit.

However, no product is without its flaws. One issue I encountered was a slight misalignment of the crankshaft, which caused the shive to be out of alignment. While this hasn't significantly impacted performance yet, it's something to keep an eye on. Given the overall build quality, I hope this is an isolated incident rather than a common issue.

In conclusion, the DeWalt 7.5-HP 80-Gallon Two-Stage Air Compressor is a powerhouse that's well-suited for heavy-duty applications. Its robust construction, powerful motor, and efficient pump make it a reliable choice for any serious workshop. While it does require some additional accessories to manage moisture and optimize performance, the investment is worth it for the long-term benefits.

Considering its performance, build quality, and reliability, I highly recommend this compressor. It's an excellent addition to any workshop that demands consistent and high-quality air supply. Whether you're a professional or a serious hobbyist, the DeWalt compressor is a tool you can count on for years to come.
