Revolutionize Your Internal Pipe Cleaning with EXAIR Back Blow Nozzles

Published on by Al WooffittLeave a comment

In industrial manufacturing, cleaning the inside of pipes, tubes, and blind holes has traditionally been a challenge. Standard forward-blowing nozzles often push debris deeper or create safety hazards by ejecting material out the far end. EXAIR solved this problem with their innovative Back Blow Air Nozzles, designed specifically to “wipe” internal surfaces clean by directing airflow backwards toward the operator.

How They Work

These nozzles utilize the Coanda effect to amplify compressed air, entraining surrounding ambient air to create a high-velocity 360-degree cone of air. Because the air is directed back toward the inlet, it pulls coolant, chips, and debris out of the opening rather than forcing them further in.

Common Applications

Manufacturers across various industries use these nozzles to improve efficiency and safety. Typical uses include:

  • Machined Part Cleaning: Removing coolant and metal chips from blind holes or internal threads.
  • Hydraulic Cylinder Repair: Cleaning honed bores ranging from 2″ to 16″ in diameter.
  • Tube & Pipe Manufacturing: Clearing debris from long lengths of pipe where forward blowing is impractical.
  • CNC Machining: Quickly cleaning out spindles between tool changes.
  • Electronics Recycling: Removing residual powder from spent toner cartridges.

Key Product Features

  • Material: Manufactured from durable Type 316 Stainless Steel for superior corrosion and wear resistance.
  • Size Range: Available in three sizes—M4, 1/4 NPT, and 1 NPT—covering internal diameters from 1/4″ to 16″.
  • Safety & Compliance: Meets OSHA standards for noise and dead-end pressure.
  • Configurations: Can be mounted on VariBlast, Soft Grip, or Heavy Duty Safety Air Guns with extensions up to 72″ and optional chip shields for operator protection.

Step 3: Upgrade Your Blow off, Cooling, and Drying Operations

Published on by Al WooffittLeave a comment

In the world of manufacturing, compressed air is often called the “fourth utility.” It’s essential, but it’s also expensive to produce. If you’re following the Six Steps to Optimize Your Compressed Air System, Step 3 is where you stop the bleeding.

Step 3, dear reader, is the subject of today’s blog.

Upgrading your blow-off, cooling, and drying operations from “homegrown” solutions to engineered products is one of the fastest ways to slash energy costs and improve plant safety.

The Problem with “In-House” Solutions

Many plants rely on makeshift blow-off devices: crimped copper tubes, pipes with drilled holes, or basic air nozzles found at a hardware store. While they seem “free” or cheap, they are incredibly inefficient.

  • High Air Consumption: They lack the physics to move air efficiently, requiring massive volumes of compressed air to do the job.
  • Dangerous Noise Levels: Drilled pipes produce a high-pitched shear that often exceeds OSHA noise exposure limits.
  • Safety Hazards: If a pipe or open tube is dead-ended against skin, it can lead to serious injury or air embolism.

The Engineered Solution: EXAIR Technology

This is where EXAIR engineered compressed air products change the game. Unlike a standard pipe, EXAIR products use the Coanda effect to “entrain” the surrounding room air. For every part of compressed air used, an EXAIR nozzle or air knife pulls in 30 to 40 parts of “free” ambient air.

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of air from the surrounding environment.

If you are drying a conveyor belt or cleaning wide sheets of material, a drilled pipe is a money pit. An EXAIR Super Air Knife provides a high-velocity, uniform sheet of air across the entire surface. It’s quiet (around 69 dBA for most applications) and reduces air consumption by up to 80% compared to open headers.

For targeted blow-off or part ejection, Super Air Nozzles replace open tubes and cheap nozzles. They provide a forceful, concentrated stream of air while meeting OSHA requirements for skin pressure and noise. You get more “push” for significantly less “psi.”

Step 3 isn’t just about blowing air; it’s about optimizing how air manages temperature and waste. From Vortex Tubes that provide spot cooling without refrigerants to Air Amplifiers for smoke and fume removal, these tools ensure you aren’t overworking your compressors for simple tasks.

The Bottom Line

Upgrading to EXAIR engineered products isn’t just a maintenance fix; it’s a financial strategy. Most facilities see a return on investment (ROI) in just weeks through reduced energy bills.

By replacing inefficient, loud, and dangerous blow-off methods with engineered solutions, you’re not just optimizing your compressed air—you’re creating a quieter, safer, and more profitable shop floor.

On Demand Ionization with the Gen4 Ion Air Jet

Published on by Al WooffittLeave a comment

Static can be a big issue, whether it is shocking operators, causing jamming of machines, or collection of dirt and debris. This is especially true in the colder months. At EXAIR we have a wide range of Static Eliminators that can handle just about every static problem. However, sometimes the issue can be concentrated in smaller areas, and the solution needs to be more precise. For these types of situations, our Gen4 Ion Air Jet is perfect.

The Gen4 Ion Air Jet is a combination of our High Velocity Air Jet, and our Gen4 Ionizing Point. The Air Jet generates a high-speed air stream using a specially designed Coanda profile. This design creates a low pressure at the Air Jet’s entrance, allowing it to pull in surrounding air at a ratio of 5:1. As a result, the Air Jet operates efficiently, producing more ambient air in its output than compressed air. Additionally, thanks to the engineered design, they produce a smooth laminar air stream that can treat a surface up to 15 feet away.

Due to the laminar nature of the airflow, the ions generated by the Ionizing Point will be carried by the air stream all the way to the targeted area. When operated at a pressure of 80psig, the Ion Air Jet is capable of dissipating a 5kV charge in under 0.18 seconds. Although for more sensitive applications, the pressure can be regulated down to adjust the airflow from a blast to a breeze.

Ion Air Jet

In addition to being efficient in its use of compressed air, the Ion Air Jet boasts several other advantages. Due to the engineered design of the High Velocity Air Jet, and the laminar airflow produced, the Ion Air Jet is very quiet compared to other compressed air blow off options. At 82dBA (when operated at 80psig), the Ion Air Jet is well below OSHA’s allowable noise level. It also meets OSHA’s dead-end pressure requirements.

The Ionizing Point used in the Ion Air Jet takes advantage of a shockless design, so it is safe to handle while in operation. As it utilizes the corona discharge method, there are no radioactive materials needed to produce the static neutralizing ions.

In addition to our standard Ion Air Jet Kits, we also have systems that combine our Ion Air Jet with our Stay Set Hoses, making hands-free operation even easier. Whether you are looking for a new solution, or looking to upgrade an existing process, give us a call and see if our efficient, low-cost Ion Air Jets can help solve your static issues.

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.

EXAIR Model 1100 Super Air Nozzle Replaces Open Copper Pipe Blow Off

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.
