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.

Stop Starving Your Tools: How to Beat Pressure Drop in Compressed Air Systems

Published on by Al WooffittLeave a comment

If you’ve ever noticed your pneumatic tools losing their “punch” or your machines throwing low-pressure faults, you’re likely dealing with the silent thief of industrial efficiency: pressure drop.

Pressure drop is the reduction in air pressure from the compressor discharge to the actual point of use. It’s not just a performance issue; it’s an expensive energy drain. Most facilities try to fix it by cranking up the compressor pressure, which is like trying to fix a leaky garden hose by turning the spigot up—it just wastes more energy and stresses the system.

Here is how to tackle it and how EXAIR products help you win the fight.

1. Size Matters (The Piping Dilemma)

The most common cause of pressure drop is undersized piping. Think of your compressed air system like a highway; if you try to cram 1,000 cars into one lane, traffic slows down.

  • The Fix: Always size your main headers and distribution lines for the maximum potential flow, not just your current average. Using a “loop” system instead of a single “dead-end” header allows air to flow in two directions to reach a high-demand tool, effectively doubling the capacity of the pipe.

2. Smooth Out the “Plumbing”

Every elbow, tee, and valve creates friction. Standard plumbing fittings often have sharp turns that create turbulence, slowing down the air.

  • The Fix: Minimize the use of 90-degree elbows where possible (use long-radius sweeps instead) and ensure you aren’t using restrictive, undersized quick-connect couplings at the tool.

3. Eliminate the “Spiky” Demand

Large, intermittent air consumers can cause the pressure in the entire line to “sag.”

  • The Fix: Use a receiver tank (surge tank) near the point of high demand. This acts as a local battery, providing the necessary volume instantly without pulling from the main header and causing a system-wide drop.

How EXAIR Combats Pressure Drop

EXAIR is built on the philosophy of “doing more with less.” Our products are engineered specifically to maximize force while minimizing air consumption, which is the most effective way to reduce pressure drop at the end of the line.

Engineered Super Air Nozzles

EXAIR Nozzles

Standard “open pipe” blowoffs are air hogs. They create massive localized pressure drops because they dump huge volumes of air inefficiently. EXAIR Super Air Nozzles use a small amount of compressed air to entrain large volumes of surrounding “free” room air.

  • The Result: You get high-velocity discharge with significantly lower compressed air demand, keeping the pressure stable for the rest of your tools.

Digital Flowmeters

You can’t fix what you can’t measure. EXAIR Digital Flowmeters allow you to see exactly where the air is going in real-time. By monitoring different zones of your plant, you can pinpoint exactly which branch or machine is causing the pressure drop, making it easy to identify leaks or bottlenecks.

Precise Pressure Regulators

Using more pressure than a process requires (artificial demand) is a leading cause of system-wide drops. EXAIR Pressure Regulators ensure that each application gets exactly the PSI it needs and nothing more. By lowering the pressure at the point of use to the minimum required, you preserve the “headroom” in your main lines.

The Bottom Line, combating pressure drop is about velocity and volume. By optimizing your piping layout and switching to high-efficiency end-use products like our intelligent, point-of-use compressed air products, you stop starving your tools and start saving on your electric bill.

Understanding OSHA and Compressed Air Safety: A Guide for Modern Facilities

Published on by Al WooffittLeave a comment

Maintaining a safe workplace isn’t just a legal requirement—it’s the backbone of a productive and healthy business. One of the most common yet overlooked hazards in industrial environments is the improper use of compressed air. In this blog, we’ll break down what OSHA is, the specific risks of compressed air, and how EXAIR products can help you stay compliant while improving efficiency.

What is OSHA?

The Occupational Safety and Health Administration (OSHA) is a federal agency within the U.S. Department of Labor, established by the OSH Act of 1970. Its mission is to ensure safe and healthful working conditions by setting and enforcing standards and providing training, outreach, and assistance.

Under OSHA, employers have a fundamental responsibility to provide a workplace free from recognized hazards—a requirement known as the General Duty Clause.

Compressed Air: The Hidden Hazards

Compressed air is a powerful energy source, but it carries significant risks if not managed correctly. OSHA focuses on two primary safety standards regarding its use:

  • Dead-End Pressure (29 CFR 1910.242(b)): Compressed air used for cleaning must be reduced to less than 30 psi (pounds per square inch) if the nozzle is “dead-ended” or blocked. Higher pressures can cause air to enter the bloodstream (air embolism), leading to serious injury or even death.
  • Noise Exposure (29 CFR 1910.95(a)): High-velocity air can be incredibly loud. OSHA sets strict permissible noise exposure limits for workers during an 8-hour shift to prevent permanent hearing loss.
  • Chip Guarding: OSHA also requires “effective chip guarding” and personal protective equipment (PPE) to protect workers from flying debris when using compressed air for cleaning.

How EXAIR Products Ensure Compliance

Many facilities struggle to balance the need for high-force air with these safety regulations. EXAIR specializes in “Intelligent Compressed Air” products designed to meet or exceed OSHA standards without sacrificing performance.

1. Safety Air Guns

EXAIR Safety Air Guns are engineered to be safe even when used with air supplies at 80–120 psi. They feature specialized nozzles that cannot be dead-ended, ensuring the static pressure remains below 30 psi:

Model 1210 Soft Grip Safety Air is fitted with an EXAIR Super Air Nozzle. We can also supply it with a Rigid Extension and Chip Shield (right).

Model 1210 Soft Grip Safety Air Gun with Model 1100T Air Nozzle, operating at just 74 dBA—well below OSHA’s 8-hour limit. Featuring an ergonomic design, this Air Gun can be fitted with zinc-aluminum, stainless steel, or PEEK plastic nozzles.

2. Engineered Air Nozzles

Instead of using open-ended pipes (which are loud, wasteful, and unsafe), EXAIR’s Super Air Nozzles use a small amount of compressed air to entrain large volumes of surrounding air. This creates a quiet, high-velocity laminar flow.

  • Safety Feature: Fins on the nozzle allow air to escape if the tip is pressed against a surface, preventing dangerous pressure buildup.

3. Chip Shields and Extensions

To meet the “chip guarding” requirement, EXAIR offers polycarbonate chip shields that can be added to any safety air gun (look for the -CS suffix on models like the 1240-CS). Extension pipes are also available to allow cleaning of hard-to-reach areas while keeping the operator at a safe distance.

Final Thoughts

OSHA inspections are often unannounced. By replacing unsafe, loud, and inefficient blow off tools with EXAIR Intelligent Compressed Air products, you not only protect your workers from injury and hearing loss but also avoid costly fines and reduce your facility’s energy consumption.

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.
