If there’s one thing I’ve learned about compressed air, it’s that pressure is a lot like coffee. A little bit gets the job done, but too much just makes you jittery and costs you more than it should. The last step in our 6 Steps to Optimizing Compressed Air series is all about dialing that pressure back to where it actually needs to be. So why worry about pressure?
Compressed air is one of the most expensive utilities in your facility. For every couple of PSI you crank the system higher than necessary, your energy bill climbs right along with it. In most cases, your application doesn’t even need that extra pressure. It’s like using a fire hose to water a houseplant.
This is where pressure regulators come in. They’re simple devices, a knob, a spring, a diaphragm, but they’re doing some heavy lifting. Twist the knob, and the spring loads or unloads. That changes how much the diaphragm allows through, and suddenly you’ve got a steady, consistent downstream pressure without overfeeding your air tools or EXAIR products.
The real magic happens when you lower that setpoint. If your Super Air Knife is blowing water off parts just fine at 60 PSIG, why run it at 100 PSIG? Less pressure means less flow, and less flow means more savings. You’ll get the same result with a smaller demand on the compressor. That’s a win-win every plant manager can appreciate.
Now, before you start cranking down knobs all over the place, keep sizing in mind. Regulators need to be matched to the volume of air your application requires. If they’re undersized, you’ll experience droop, when the pressure drops off during demand spikes. EXAIR takes the guesswork out by offering properly sized regulators in kits with a lot of our products. We’ve already done the math so you don’t have to.
Turning down the pressure might be the last of the six steps to optimizing compressed air, but it’s one of the easiest changes to make and one of the fastest ways to save. A couple twists of the regulator could be all it takes to lighten the load on your compressor, cut operating costs, and keep your system running lean and efficient.
And if you’re not sure where to start, that’s what our Application Engineers are here for. Call us, chat with us, or shoot us an email. We’ll help you find the right pressure for your setup without the trial and error.
EXAIR is now partnering with EasyCAS by DirektIn software. This tool lets you actually measure and validate the savings you’re getting from steps like lowering pressure and implementing engineered solutions. No more guessing, you’ll have hard data showing how much air and money you’re saving.
