Graco 390 PC Cordless Airless Paint Sprayer


Store extension cords, the Graco Wireless 390 PC is here to stay

Graco is revolutionizing the paint industry by pushing the limits of what a cordless paint sprayer can do. You might recognize the general appearance of the Graco 390 PC Cordless Paint Sprayer modeled after the 390 PC Corded. While there are other cordless paint sprayers on the market, Graco is the first to offer one at this level.

Graco 390 PC Performance Cordless Paint Sprayer

A single DeWalt FlexVolt 6.0Ah battery powers this airless paint sprayer, however, the kit includes a second 6.0Ah battery and a fast charger. Because it operates at 60 volts max (54 V nominal), it will not work with 20 V max batteries from DeWalt.

The sprayer’s brushless motor can handle up to 3 gallons on a single charge at flow rates up to 0.47 GPM using tips up to 0.021 inch. You can control the pressure between 0 and 3300 PSI by simply turning the pressure control knob. This is a big deal because it produces the same performance as the 390 wired PC.

Plus, with the right settings, you can cover almost 1,200 square feet with just one battery. With the fast charger that puts each battery back into the game in about 60 minutes, you have a real chance of working continuously all day depending on how professional painters typically use the wired 390 PC.

Of course, since you’re cordless, that means you can set it up quickly without dragging any extension cords around the jobsite. One of the other big advantages of working with DeWalt for the power source is that replacement batteries are easily available nationwide.

Graco 390 Wireless PC Design Notes

Overall, it’s a pretty solid machine, and that shouldn’t come as a surprise. If you are familiar with the 390 wired PC, you simply swap the cord for a battery.

The footprint of this machine is quite modest, measuring just 18.5 inches in height and 14 × 16 inches at the base. It is also available in the Hi-Boy frame if you prefer to have it on wheels.

Durable construction

Graco’s Endurance piston pump promises twice the life of the next leading brand. V-Max Blue trims, Chromex rod and hardened stainless steel cylinder back this claim. The pump design also includes a QuikAccess intake valve which speeds up cleaning.

Moving on to the transmission, Graco uses hardened steel for the gearing of its Advantage Drive. In addition to providing quieter operation, they are backed by a lifetime warranty.

As expected, the frame is made of steel with a thick chrome coating.

Maintenance and cleaning

The ProConnect Pump Replacement System allows you to quickly replace pumps in minutes. You’ll need a few tools, but it’s nice that you don’t have to leave your machine in the repair shop.

The Graco 390 Cordless PC also features an “Easy Out” filter to reduce the risk of clogging at the spray tip. This design is similar to a cartridge oil filter on a car. To clean, just unscrew the steel cap and remove the filter, and clean depending on what you’re spraying.

As with any sprayer, you should run water through the system at the end of the day. Keep in mind that you want to have a battery on the charger so that there is enough juice at the end of the day for cleaning.

Keep your feet on the ground

The Graco 390 Cordless PC can spray a variety of materials, making it incredibly useful for professional painters. An important safety feature of this sprayer is the ground wire, which is a change from corded sprayers which use a 3-prong plug for grounding.

Be sure to ground the machine while spraying flammable liquids like xylene or other thinners to reduce the risk of injury. As the first in its class, it is worth reading the manual carefully before putting this machine into service.

Just one thing…

The only thing we really want for this sprayer is a hybrid power system so that we can plug it into an outlet as another option. This would be especially useful at the end of the day when we are outside with running water in the system or when someone forgets to charge a battery. Of course, DeWalt could fix that for this product and the entire FlexVolt line with a 60V AC adapter, but don’t hold your breath while waiting.

Graco Wireless 390 PC Wireless Price

Like most tools, there is a premium for cordless convenience. Expect retail prices to hit $ 2,500 for the kit which includes everything you need to get started except paint:

The bottom line

We entered this question wondering if the battery-powered wireless Graco PC390 could be more than just a punch list tool, as many early wireless conversions are. It’s clear to us that this is a complete replacement, delivering the same performance as its wired counterpart without the hassle of extension cords. While price can be a sticking point for some, the convenience factor is a big selling point for painters looking to use their time in the most efficient way possible. Plus, it’s made in the USA using global components.
