For years, the ARB Twin has been the undisputed king of high-performance off-road air compressors. Matt McClellan of Ozark Overland Adventures put that reputation to the test against a powerful new challenger: the Morrflate 10-6 PSI Pro. He pitted the two head-to-head in a timed tire inflation test to see if the new kid on the block could actually outperform the industry’s benchmark dual air compressor.

A Closer Look at the Morrflate PSI Pro

The Morrflate is designed primarily as a portable unit, coming with a carrying case and large alligator clips. Its standout feature is a digital screen that allows someone to just set it and forget it afterwards. “You can set the psi Target that you want to get to with your tires, and then it automatically shuts itself off,” Matt explained.

This allows the user to walk away and socialize at the end of a trail run without having to constantly monitor a gauge. Matt also gave a piece of advice for any high-output compressor: “Don’t buy one of these high cfm compressors to just air up one tire because that’s a complete waste.”

Dual Air Compressor Showdown

The test was simple: air up four large off-road tires simultaneously from 17 psi to 38 psi and see which compressor was faster. The new Morrflate 10-6 PSI Pro boasts a massive 10.6 cfm rating. The ARB Twin, by comparison, has a 6.16 cfm rating and requires the user to manually monitor the pressure.

The Head-to-Head Results

The Morrflate 10-6 PSI Pro was up first. Using its auto-shutoff feature, it hit the 38 psi target and turned itself off in just under six minutes. Next, Matt hooked up the ARB Twin to an identical set of tires and started the clock.

The ARB finished the same task in 9 minutes and 12 seconds, more than three minutes slower than the Morrflate. “I’m absolutely blown away at the performance of that 10-6 PSI Pro,” Matt said after the test.

A New Air Compressor Industry Standard?

The speed difference was dramatic, but the price difference makes the result even more significant. As Matt pointed out, with the Morrflate, “you get an air compressor that actually puts out more air than the ARB twin for half the money.”

This new dual air compressor also comes standard with the automatic shut-off feature, which is an expensive add-on for the ARB. In the end, the test was a complete blowout. As Matt concluded, “This is the industry standard, the ARB twin, and it just blew it out of the water.”
