The Invisible Nuisance: Where Static Electricity Comes From and How to Kill It
We’ve all experienced it: the sudden “zap” when touching a doorknob, the frustration of plastic wrap sticking to everything but the bowl, or the sight of dust stubbornly clinging to a freshly painted surface.
While static electricity is a minor annoyance at home, in an industrial environment, it’s a productivity killer. It causes materials to jam, ruins electronic components, attracts contaminants, and can even pose a significant fire hazard.
But where does it actually come from? And more importantly, how do you get rid of it?
At its core, static electricity is an imbalance of electric charges on the surface of a material. Most objects are electrically neutral, meaning they have an equal number of positive protons and negative electrons. Static is generated through a process called tribocharging. When two materials come into contact and then separate, electrons are “ripped” from one surface and transferred to the other.
Common industrial culprits include:
Friction: Material pulling off a roll (webbing) or sliding down a conveyor.
Pressure: Objects being squeezed through rollers.
Separation: Rapidly peeling a protective film or label.
In a perfect world, these charges would bleed off into the air. However, in dry environments or when using insulators (like plastics, paper, and textiles), the charge gets trapped on the surface. It stays “static” until it finds a way to discharge—usually into your hand or a sensitive piece of equipment.
So why is static a nightmare for production? If you are running a high-speed line for example, static electricity manifests in three expensive ways:
Dust Attraction: A charged surface acts like a magnet for airborne contaminants, leading to poor paint finishes or contaminated food packaging.
Product Misbehavior: Sheets of paper might double-feed, or plastic parts might “fly” off a conveyor belt due to repulsion.
Operator Shocks: Repeated painful shocks lead to fatigue and safety concerns for your team.
This is where EXAIR’s Gen4 Static Eliminators come in. You can’t always stop the friction that creates static, but you can neutralize the charge immediately after it’s formed. Unlike simple grounded brushes that need to touch the surface, EXAIR products use ionizing technology combined with compressed air to neutralize charges from a distance.
Through the use of the Corona discharge method, EXAIR ionizers create a flood of both positive and negative ions. When this “cloud” of ions hits a charged surface, the surface automatically attracts the ions it needs to become neutral. Several common applications for our products are:
Ionizing Bar: High-speed webs, paper, and flat surfaces.
Ion Air Cannon: Neutralizing parts from a distance or in hard-to-reach areas.
Ion Air Gun: Manual cleaning and neutralizing of parts before painting or packaging.
Super Ion Air Knife: Providing a wide “sheet” of ionized air to clean and neutralize large surfaces simultaneously.
So why choose EXAIR? Our Gen4 technology is designed for rugged industrial use. They are shock less, meaning they are safe for operators to be around, and they require no moving parts, which translates to incredibly low maintenance. By integrating these into your process, you can increase line speeds, reduce scrap, and keep your workplace safe.

Axial vs. Deflector: Which BETE Fan Nozzle Really Makes the Cut?
Since BETE became part of the EXAIR family back in 2024, we’ve been able to offer a much deeper bench of spray technology to solve the more complex fluid delivery problems our customers face. When you need precision in a spray process, choosing the right pattern is just as critical as the fluid you’re pumping. Fan nozzles are the go-to when you need a flat sheet of liquid with a specific impact. Whether you’re washing down a conveyor or applying a thin coating to a part, the goal is uniform distribution and, often, high force.
There are two primary ways these fan patterns are created: axial and deflector. With an axial fan nozzle, the liquid exits through an orifice and naturally widens into a flat spray. These are great for general cleaning and washing because they provide a tapered edge. This is perfect for overlapping multiple nozzles on a header to get seamless, uniform coverage across a wide area without any “light” spots between nozzles.
Then you have deflector-style nozzles. In this design, the fluid hits an external surface after exiting the orifice, which “peels” the liquid into an extra-wide fan. Because the fluid is deflected, these nozzles can achieve a much higher impact at lower flow rates, making them ideal for heavy-duty scrubbing, rinsing, or suppressing dust.
We see these used across a ton of different industries because of that versatility. In food and beverage, they’re a staple for bottle and container washing. In the steel industry, you’ll find them cooling down rolls or applying lubricants. They even play a huge role in fire protection, specifically in deluge systems where you need to move a lot of water quickly and accurately.
The main takeaway is that fan nozzles are the best choice whenever you have relative motion between the nozzle and the target. If you have a product moving down a line that needs to be wetted, coated, or cleaned, a fan pattern is likely the most efficient way to get it done.
Between EXAIR’s compressed air expertise and BETE’s industrial spray nozzle catalog, we can help you spec out the right nozzle for the job. Give us a call and we’ll walk through the flow rates and spray angles your application requires.

Care and Feeding Of Your Reversible Drum Vac
EXAIR’s Reversible Drum Vac couldn’t be easier to operate. Thread it in to the 3/4 NPT vent connection on your drum lid, install the Standpipe & Hose on the 2 NPT bung, hook up a compressed air line to it, and you’re in business. As long as your compressed air is clean & moisture free, your Reversible Drum Vac will run like new for a long, long time.
Should you start to see a decrease in performance, though, the first thing you’ll want to do is verify the compressed air supply, especially if something’s changed:
- Did you get a new hose? The Reversible Drum Vac uses 19 SCFM @80psig for rated performance. That’ll require a 3/8″ ID hose, assuming a length of no more than about 20ft.
- Are there any restrictions in the line? The usual suspects are clogged filters, partially closed valves, or push-to-connect quick-connect fittings.
- Are there any vacuum leaks in the hose, its cuffs, the drum, or either threaded connection? If the lid’s removable, is that gasket intact?
If you’ve eliminated all of those potential problems, it’s time to take a look at the Reversible Drum Vac itself. The Reversible Drum Vac has tight internal passages that contamination from even the cleanest compressed air systems can build up in, over time. Good news is, we made it super easy to disassemble & clean, and better news: this almost always restores it to as-new performance. We even have a video that walks you through it:
You may be surprised not at how much, but how little contamination you find inside the Reversible Drum Vac. We offer factory refurbishment service for them as well…the procedure in the video is step-by-step what that service consists of, except we also replace the Shim, O-Rings, & Float, and when we reassemble it, we verify performance on the same fixture that every single new Reversible Drum Vac that we build gets tested on. Recently, a customer sent a Reversible Drum Vac in for refurbishment services after we’d spent some time talking on the phone, exchanging emails, and even a brief Engineering Consultation web meeting, troubleshooting their loss of vacuum. I was particularly curious about this one, so when it came in, I tested it (on our calibrated test fixture) for performance, and found it was only generating about 22% of rated vacuum, and only 17% of rated flow. I figured it was clogged (with a capital CLOGGED) so I match marked the body & plug (just like we show in the video) and took it apart:
We then completed the Refurbishment Service and tested it again. Performance was verified to be within specification for a new High Lift Reversible Drum Vac.
I offer to share the Cleaning & Refurbishing video with just about anyone who calls to discuss performance (or lack thereof) of their Reversible Drum Vac. Some still want to send theirs in for Refurbishment Service, and that’s fine. If you have a Reversible Drum Vac that’s not working properly, I’m here to help you get the most out of our products — any of them — give me a call.

Unlike electric vacuums that suffer from motor burnout or impeller clogs, our drum vacs are powered entirely by compressed air. This means:
- Zero Maintenance: With no moving parts to wear out, these systems run nearly indefinitely.
- Electrical Safety: Eliminating electricity removes the risk of shock in wet environments.
- Quiet Operation: Our systems operate at significantly lower noise levels than traditional industrial vacuums.
2. Two-Way Action for Maximum Versatility
The “Reversible” in our name is a game-changer. With a simple turn of a knob, the same stainless-steel pump that filled your drum in under two minutes can reverse the airflow to empty it just as quickly.
- Application Spotlight: Laboratory operators have used our Mini Reversible Drum Vac to pump waste from under-lab tanks and then easily discharge it into reclamation vessels.
3. Power When You Need It: The High Lift Advantage
For more “vertical” challenges, the High Lift Reversible Drum Vac provides the extra suction needed to move thick liquids (up to 1400 cPs) or lift fluids up to 15 feet.
- Application Spotlight: A ferry operator uses the High Lift RDV to clean out engine room bilges, while a construction firm uses it to recover heavy slurry from concrete cutting—tasks that would kill a standard vacuum.
4. Built-In Safety & Speed
Our systems are engineered for industrial speed without sacrificing safety:
- Auto-Shutoff: An internal float stops the vacuuming process once the drum is full, preventing messy overflows.
- Rapid Filling: The High Lift model can fill a 55-gallon drum in just 85 seconds.
From cleaning up condiment spills in food processing to recovering hydraulic oil leaks in precast concrete plants, EXAIR drum vacs are the ultimate industrial housekeeping tool.
