Ingersoll Rand 2146Q1MAX 3/4-Inch Impact Wrench

Ingersoll Rand 2146MAX the First to Feature Visual Air Pressure Gauge

IR claims that the worst thing for a technician is starting a job and getting stuck. That’s why Ingersoll Rand views the visual air pressure gauge on the 2146Q1MAX 3/4-Inch Impact Wrench as so important. This gauge acts as a performance indicator that tells you that the tool is ready for the job before you even start.

What Is Ingersoll Rand Saying About the 2146Q1MAX?

It’s always been a mystery – how much air is a pneumatic tool getting? Mystery solved. The integrated air pressure gauge on the Ingersoll Rand 2146Q1MAX ¾” provides the answers technicians need to know they are operating the impact at optimal power.

What’s the Big Deal?

The onboard visual air pressure gauge on the Ingersoll Rand 2146Q1MAX Impact Wrench sits at the back of the tool, letting you monitor the air pressure ranging from 60 psi to 120 psi. When the gauge indicates that the tool is operating at the prescribed 90 psi, the gauge will show green. If the gauge shows yellow, you know the tool has low air pressure running to it. If the gauge shows red, the tool is operating at an air pressure rating that is too high.

Ingersoll Rand tells us that running a pneumatic tool at a higher air pressure than it’s rated for will put undue stress on the tool, shortening its life. Operating below the recommended air pressure will not supply the tool with enough power to tighten properly. According to Ingersoll Rand, the power gauge on the 2146Q1MAX Impact Wrench gives you control and efficiency while saving money by minimizing wasted compressed air.

Ingersoll Rand also claims that the 2146Q1MAX Impact Wrench offers the most powerful 3/4-inch wrench in its class. Its quiet, six-vane motor removes stubborn bolts easily, delivering up to 2000 foot-pounds of nut-busting torque.
