Why Engineered Air Nozzles Outperform Open Pipes (And Cut Air Use by Up to 70%)

Published on by Jordan T ShouseLeave a comment

Compressed air is one of the most expensive utilities in any manufacturing facility—yet it’s often treated as “free.” One of the biggest contributors to wasted compressed air is the continued use of open pipes, drilled pipes, or homemade blowoffs for cleaning, drying, and cooling applications.

While these methods may seem simple and inexpensive, they are inefficient, unsafe, noisy, and costly over time. EXAIR Engineered Air Nozzles are designed to solve these exact problems. Often reducing compressed air consumption by up to 70% while improving performance.

Open pipes release compressed air directly to atmosphere with no control, no amplification, and no optimization. This creates several major issues:

Excessive Air Consumption

An open 1/4″ pipe at 80 PSIG can consume 25+ SCFM continuously. Multiply that across shifts, days, and multiple stations, and the cost quickly adds up.

Poor Performance

Open pipes create turbulent airflow that dissipates rapidly, requiring higher pressure and more air to achieve acceptable results.

High Noise Levels

Uncontrolled air release produces noise levels that can exceed OSHA limits, creating safety and compliance concerns.

Safety Risks

Open pipes can generate dangerous dead-end pressures and flying debris, posing serious injury risks to operators. Creating real situations where

What Makes EXAIR Engineered Air Nozzles Different?

EXAIR Engineered Air Nozzles are precision-designed to maximize force while minimizing air consumption. Instead of wasting compressed air, they use advanced airflow geometry to do more with less.

Air Amplification

EXAIR nozzles use the Coandă effect to entrain surrounding ambient air. For every unit of compressed air used, multiple units of free air are pulled into the flow—creating higher output force without increased air usage.

Optimized Flow Patterns

Rather than chaotic turbulence, engineered nozzles produce laminar, focused airflow that delivers better cleaning, drying, and cooling results at lower pressure.

Significant Air Savings

It’s common to see 30–70% reductions in air consumption when replacing open pipes with EXAIR air nozzles—often with improved performance.

Eleminate Safety Risks

Air nozzles and jets are designed to operate well above 30 PSIG while creating dead end pressures well below the OSHA limits. Giving you better performance safley.

Replacing open pipes with EXAIR Engineered Air Nozzles is one of the simplest and most cost-effective improvements you can make to a compressed air system.

If you’re serious about:

  • Reducing energy costs
  • Improving safety
  • Lowering noise levels
  • Getting more from your compressed air

…it’s time to stop blowing money into the air.

EXAIR Engineered Air Nozzles prove that better design beats brute force—every time.

Feeling Exhausted?

Published on by Brian FarnoLeave a comment
Our current calendar.

The school year has started here in Cincinnati. For some families, it’s the very first year in the school system; for others, it’s the last. Every year in between brings its own mix of emotions. Personally, I look forward to the sports and events, watching the camaraderie grow between my daughters, their friends, and their teams.

This year, we have a 10th, 7th, and 5th grader. One is about to get her learner’s permit, one is trying out for school volleyball, and one is in her final year of elementary. It feels like a big year all around. The pace of activities has been so fast that it’s hard to fully process what’s happening—and that same thing can easily happen in our work lives.

At home, my wife and I often feel like we’re treading water, bouncing from one thing to the next. We use downtime not just to catch our breath, but also to talk through what’s working, what’s not, and how to prepare better for the weeks ahead. When we skip those conversations, tension builds, and we end up storming as a team. The same holds true in a production environment: without regular evaluation and planning, the whole system suffers.

In manufacturing, output rarely stops. Even when a sector halts for a planned shutdown, the project list is carefully managed to minimize disruption. The focus is always on keeping production moving—whether that means picking up speed, adding shifts, or running longer hours. But smooth production depends on proactive planning.

Take compressed air systems as an example. A simple habit like measuring pressure drop across filters can prevent costly downtime. By installing pipe tees and pressure gauges upstream and downstream of filters, you can monitor performance. Once the differential hits 5 psig, it’s time to plan for an element replacement. Adding this to a maintenance schedule and aligning it with your purchasing cycle turns an unexpected expense into a controlled, predictable one.

Pressure gauges and filters with indicators are both great options for monitoring filter performance.

Just like meal prep and calendar reviews keep our family life running more smoothly, preventive maintenance and equipment monitoring keep production lines efficient. For parents entering the whirlwind of school activities—hang in there. Build a community with the other parents around you. It truly takes a village, just like it takes every department working together to deliver a finished product.

Air Cooling Maintenance?

Published on by Brian FarnoLeave a comment

The time has finally come, and spring is here! The Cincinnati Reds are playing, Spring Soccer is happening early on Saturday mornings, and the FC Cincinnati Stadium is bustling here in Cincy. With that, temperatures are climbing, the grass and weeds are growing, and more and more families are out walking around and doing outdoor activities. With this, also comes warmer temps, and lots of spring allergies in the Farno household. As a dad, I have stepped into my role pretty well by trying to delay turning on the air conditioner until everyone else in the house is plotting my demise. This year, I achieved it by putting off the routine maintenance of the condensing coils.

In case you weren’t aware, here in the Midwest, where pollen runs rampant and the winds have been strong this year, it is a great idea to clean out the condensing coils on your home’s A/C system before turning it on for the year. Unfortunately, your home A/C system is not maintenance-free like the Cabinet Cooler Systems EXAIR offers; at the same time, your home needs a lot more than a few thousand BTU/hr of cooling capacity. When we first bought the home, I didn’t know this was a thing, as the home I grew up in didn’t have central air. We rocked Window A/Cs, and my parents still do. So, cleaning the outdoor unit was not part of my knowledge base. This is something I learned once the air conditioner wasn’t working, and I started to troubleshoot.

The main purpose of the condensing coils is to strip all the heat out of the refrigerant and get it to “condense” back into its liquid state to be pushed back through the orifice and continue to cool the air that is being passed over the A Coils inside the house. These coils are covered in fins that are very tightly spaced. The outside unit has a large fan that pulls the surrounding air in through the coils and exhausts the hot air up out of the top. There is no filter on that incoming ambient air, though, so all the leaves, cobwebs, pet hair, pollen, dirt, mulch, you name it, get pulled up into these fins. Over time, this starts to get a buildup, and the cooling fins will start to lose their efficiency. The fan won’t be able to pull as much air through, and eventually, the gas doesn’t get condensed, which then reduces the cooling and can cause other bigger issues. This is just like a refrigerant-based A/C panel cooler in a facility. Most of the time, they have at least a small filter on the air intake to try and reduce the contamination of the condensing coils. So I clean the A/C condenser at my house using a coil cleaning solution diluted down, a pump sprayer, and a regular garden hose.

The main thing to remember when cleaning this is that the majority of the dirt is from the air being pulled into the center by the fan. So I rinse the coils from the inside out and make sure I have free passage all the way through. The water doesn’t need to be a high-pressure rinse like an OmniStream nozzle or one of BETE’s NF Nozzles, just a simple low-pressure stream of water to get between the fins and push all contaminants as well as rinse the solution away. Remove any leaves or other unwanted debris from inside the unit and then bolt the fan and cage back down. Then let the family enjoy some cold air inside the house.

This type of maintenance is something that easily gets overlooked when looking at refrigerant-based electrical panel coolers. That is where EXAIR Cabinet Cooler Systems shine. The only filter you have to worry about is a redundant point-of-use compressed air filter that is included with the Cabinet Cooler Systems. No chemicals needed for cleaning, no water, no mess to change out a compressed air filter, just long-lasting performance. If you want to talk about how to change your control panels over to Cabinet Cooler Systems, contact an Application Engineer today.

Downtime: It Isn’t Always BAD

Published on by Brian FarnoLeave a comment

When you say Downtime in an industrial or manufacturing setting, it may easily carry a negative connotation. This means that the output of production is not happening and input to production has halted as well. If this is not planned, it is absolutely a worst-case scenario. In our personal lives, though, downtime generally doesn’t have a negative meaning behind it. That’s the time to disconnect and recharge to maximize your output after you return to production and that is exactly what I had the luxury to do recently. This is also a message I received from a person I look up to and trust in their experiences. Vacation time can be looked at similar to a preventative and planned downtime of equipment. Without it we just wear down and eventually productivity grinds to a halt. While hanging out at a lake with my daughters this past week, I helped them hone their fishing skills. They each baited their own hooks with worms and chose their spots. We completely slayed some bluegills, and released every single one of them.

The calm of a storm rolling in when you have nothing to do is serene.

Prescribed maintenance, preventative maintenance, vacations all help to build back into the production of whatever good or service the company provides. The entire production of a facility all starts with the utilities, energy, water, compressed air, steam, other compressed gases, and the personnel. If your power input isn’t maintained, monitoring connections and disconnects, you can find yourself with a lack of service, resulting in dangerous situations. City water is often required for processes or for the facility to function properly, even an office building needs it for plumbing, fire suppression, and drinking. Steam, compressed gases and compressed air may all be required by the processes.

Servicing the compressed air where it starts is one of the most critical steps in operating a compressed air system. Making sure that your compressor has the minimum downtime, all starts with the preventative and prescriptive maintenance. One of the first tasks should always be changing and monitoring the intake air filter. Like Russ Bowman said a while back in his blog, take a deep breath, if you sneeze or smell something that is from the intake air your nose just took in from the surrounding area. That’s even after your nose hair has already partially filtered air intake. Your compressor is no different. If you let it suck up debris, dust, and pollen, then it is eventually going to have a failure. Instead of sneezing, it may burn up a vane, valve, scroll or screw. That is going to be a considerably higher cost and longer downtime than just performing the manufacturer’s listed items to maintain optimal performance.

The compressor shown above according to the caretaker receives a regular change on the airfilter every month. This is just before the cleaning and changeover. Not only do they change the filter, they make sure to clean the entire housing inside and out. That’s one of the ways this compressor has lasted with minimal downtime over the past 20 years.
