Protecting Precision: Air Wipe Ensures Accurate Measurements

Published on by Tyler DanielLeave a comment

Imagine investing in a high-end laser measurement system, capable of gauging product dimensions down to fractions of a micron, only to have the readings thrown off by something as small as a speck of dust or a thin film of residue. For one of our customers, who specialize in repairing and calibrating laser gauges, this wasn’t just a “what if.” It was a real challenge that needed a reliable solution.

The answer came in the form of EXAIR’s Air Wipe.

In their setup, cylindrical products pass through a laser gauge that verifies their diameter. Any contamination on the surface risks altering the accuracy of that measurement. By installing an Air Wipe just upstream of the gauge, they created a 360° wall of compressed air that strips away residual coolant, debris, or dust. The result is a clean, consistent surface before every scan — ensuring the gauge is reading the product, not the contaminants.

Split ring design eliminates the need for product “threading” through the Air Wipe.

The beauty of the Air Wipe lies in its design. A hinged, split-body housing makes it easy to install around existing lines, while the engineered air gap creates a uniform, high-velocity sheet of air that fully encircles the product. Unlike multiple nozzles aimed at different angles, the Air Wipe eliminates guesswork and guarantees complete coverage without gaps.

This customer chose it for metrology, but the same principle applies across industries:

  • Extrusion lines use Air Wipes to remove cooling water from plastic or rubber profiles.
  • Wire and cable manufacturers rely on them to dry and clean before printing or spooling.
  • Pipe and tubing producers install them before coating or inspection processes.
  • Medical and electronics manufacturers trust them when cleanliness and precision are non-negotiable.

For this customer, the Air Wipe turned a potential weak point in their process into a strength. Instead of worrying about contaminants interfering with measurement, they can now focus on providing precise, reliable results for their clients.

It’s a simple solution that makes a big difference: when the measurement has to be right, start by making sure the surface is clean. EXAIR offers a wide variety of products that utilize a laminar flow of compressed air for cleaning, cooling, and drying operations. Give us a call today to discuss your application!

Sanitary Flange Line Vac for Hygienic Material Transfers

Published on by Tyler DanielLeave a comment

The Sanitary Flange Line Vac was developed out of repeated requests from customers in the food, pharmaceutical, and dairy industries. For years, we built custom versions when applications called for hygienic connections, but the demand grew to the point where it made sense to make them a standard, stocked product.

This style of Line Vac uses ISO 2852 sanitary flange connections on both the intake and the outlet. These connections are common in clean-in-place (CIP) environments where systems need to be taken apart quickly for washing and sterilization. The design uses a sealing gasket between the flanges, which is compressed by a clamp to create an airtight seal. This allows the system to be disassembled, sanitized, and reassembled with minimal downtime—critical in industries where cleanliness is non-negotiable.

Constructed from 316 stainless steel, the Sanitary Flange Line Vac provides excellent corrosion resistance while maintaining the same performance as our smooth or threaded Line Vacs. For applications requiring even more power, the internal generator holes can be drilled to match the performance of our Heavy Duty Line Vacs.

Machine builders and end-users benefit from having a conveying solution that integrates directly with their existing sanitary piping. Whether you’re conveying powders, granules, or bulk ingredients, the Sanitary Flange Line Vac installs seamlessly into a system designed to meet stringent hygiene standards. It eliminates the need for adapters or makeshift connections, saving both time and hassle during installation and maintenance.

As with all Line Vacs, these units are powered by compressed air. There are no motors, no moving parts, and no maintenance. The result is a reliable, durable conveying solution that’s built for environments where cleanliness and compliance are top priorities.

A recent example involved a food manufacturer that needed a hygienic way to reclaim spilled rice from their process floor. By installing a Sanitary Flange Line Vac, they were able to automate recovery, keep the area clean, and maintain compliance with their wash-down requirements.

The Sanitary Flange Line Vac is a specialized tool, but one that solves real problems for food, pharmaceutical, and dairy applications. By offering it from stock, EXAIR makes it easy to upgrade conveying systems with a product designed for efficiency, safety, and the strict hygiene requirements of your industry.

The Hidden Costs of Inferior Compressed Air Products

Published on by Tyler DanielLeave a comment

Compressed air is one of the most versatile utilities in industry. It’s used for everything from part drying and debris removal to cooling and conveying. But not all compressed air products are created equal. Too often, I come across shops and plants relying on drilled pipes, open tubes, or cheap plastic nozzles to get the job done. On the surface, these might seem like quick and inexpensive fixes. In reality, they end up costing much more in wasted energy, unnecessary noise, and lost productivity.

Let’s start with drilled pipes and open-ended blow offs, since they’re some of the most common culprits. At first glance, they look like an easy solution. Just drill a few holes, hook up compressed air, and let it blast away. The problem is they waste a tremendous amount of air. They’re also extremely loud, often well above OSHA’s permissible noise levels outlined in 1910.95(a). In many cases, the sound exposure can reach levels that require hearing protection just to operate nearby. Beyond that, drilled holes create a dead-end pressure condition that violates OSHA 1910.242(b), which states that compressed air used for cleaning must be regulated to 30 PSIG if dead-ended. This is a serious safety concern that’s often overlooked until an injury or compliance audit brings it to light (or even worse, an OSHA inspection).

These wasteful and loud modular plastic tube blow offs…

Cheap nozzles and modular coolant hoses being used for compressed air fall into the same trap. They’re not designed to handle the pressures and flows involved in compressed air applications. This means poor performance, higher operating costs, and, in many cases, premature failure. It’s not unusual to see these hoses break down or simply pop off, creating unsafe conditions on the floor. What seemed like a cost-saving shortcut turns into downtime, frustration, and more expense down the road. The high consumption of these devices also leads to pressure drops elsewhere in your compressed air system.

This is where engineered solutions from EXAIR make the difference. Every nozzle, air knife, and air gun is designed with efficiency and safety at the forefront. Engineered nozzles, for example, reduce compressed air consumption while maintaining or even amplifying force. They also dramatically reduce noise levels, often bringing them into full OSHA compliance. Products like the Super Air Knife provide uniform airflow across an entire length while using a fraction of the air compared to drilled pipes.

In a previous blog, we shared an example where a customer was using a ¾” drilled pipe for blowoff on their production line. By replacing it with a 12” Super Air Knife, they reduced their compressed air consumption by over 80 SCFM. At their energy rate, this translated into more than $5,000 in annual savings, with a payback period of just a few months. Not only did they cut their energy bill, but they also eliminated an OSHA noise hazard and brought their system into compliance with dead-end pressure regulations.

When you factor in the rising costs of energy, the difference is not small. Inefficient or inferior products consume more compressed air than necessary, which means compressors work harder, energy bills rise, and maintenance intervals shorten. On the other hand, using an engineered solution is an investment that pays itself back quickly, often in months (or days) rather than years.

With engineered EXAIR products, you’ll improve efficiency, cut costs, reduce noise, and create a safer workplace. The short-term convenience of “cheap and easy” rarely holds up against the long-term benefits of doing it right the first time.

Turn it Down: Save Money by Reducing Compressed Air Pressure

Published on by Tyler DanielLeave a comment

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.
