Meet the Next Evolution in Industrial Cleanup: The EasySwitch Wet-Dry Vac — Now Available in ATEX

Published on by Jordan T ShouseLeave a comment

In fast-paced industrial environments, cleanup demands can change in seconds. One moment you’re recovering spilled coolant, the next you’re vacuuming metal chips or fine dust. Equipment that can’t keep up slows productivity, increases risk, and drives maintenance costs. That’s where the EXAIR EasySwitch Wet-Dry Vac changes the game — and now, with the introduction of the ATEX version, it’s ready for even the most hazardous environments.

One Vacuum. Two Modes. Zero Downtime.

The EasySwitch Wet-Dry Vac was engineered to eliminate one of the most common pain points in industrial housekeeping: switching between wet and dry cleanup.

Traditional vacuums often require time-consuming filter changes, tools, or even separate units. The EasySwitch simplifies this process with a patented, tool-free design that allows operators to transition from liquid recovery to dry debris removal in seconds.

A single latch releases the filter element for quick removal when moving to liquid mode — then reinstalls just as easily for dry applications.

Powered by Air — Not Electricity

Unlike electric shop vacs that rely on motors prone to wear, the EasySwitch operates entirely on compressed air.

This pneumatic design delivers several operational advantages:

  • No motors to clog or burn out
  • Maintenance-free operation
  • Safe for liquid recovery
  • Continuous duty capability
  • Reduced risk of electrical hazards

With no moving parts in the vacuum generator, reliability increases while maintenance requirements drop — a major win for plant managers and maintenance teams alike.

Not that it’s particularly difficult to change the filter in my trusty shop vac, but this is indeed an “Easy Switch”.

Introducing the ATEX EasySwitch: Built for Explosive Atmospheres

For facilities operating in hazardous locations, standard equipment isn’t enough. That’s where the ATEX-rated EasySwitch Wet-Dry Vac comes in.

ATEX certification refers to equipment approved for use in potentially explosive atmospheres — environments where flammable gases, vapors, mists, or combustible dust may be present.

These include industries such as:

  • Chemical processing
  • Oil & gas
  • Paint & coatings
  • Food processing (combustible dust)
  • Pharmaceutical manufacturing

The ATEX EasySwitch is engineered to mitigate these risks through explosion-protected design, allowing safe pneumatic vacuum operation in classified hazardous areas.

Because the EasySwitch already operates without electricity, it provides a strong foundation for hazardous-location safety — now enhanced with ATEX compliance for regulated environments.

The Bottom Line

The EasySwitch Wet-Dry Vac redefines industrial cleanup with:

  • Instant wet/dry conversion
  • Tool-free filter changes
  • Pneumatic, maintenance-free operation
  • Powerful vacuum performance

And now, with the ATEX version, it extends those benefits into the most demanding and hazardous work environments.

Whether you’re managing coolant recovery on the shop floor or maintaining compliance in explosive atmospheres, the EasySwitch platform delivers the flexibility, safety, and performance modern industry demands. If you have any questions, please reach out.

Efficiency: Air Tools That Pay for Themselves

Published on by Jordan T ShouseLeave a comment

In manufacturing, compressed air is often called the “fourth utility.” Like electricity, water, and gas, it’s essential for keeping production running. But unlike the others, compressed air is frequently misapplied, or wasted, making it one of the most expensive utilities in a plant.

The good news is that the right tools can dramatically improve compressed air efficiency. In many cases, they pay for themselves quickly through energy savings, reduced downtime, and improved productivity. That’s where EXAIR engineered compressed air products come in.

Let’s look at a few examples of air-powered tools that deliver measurable ROI.

Air Amplifiers: Move More Air with Less Energy

Moving large volumes of air is a common requirement in industrial environments—whether for ventilation, drying, cooling, or removing fumes. Traditional compressed air nozzles can consume a lot of air while producing relatively small airflow.

Model 120024 4″ Super Air Amplifiers are commonly used to exhaust welding smoke and fumes.

Air Amplifiers use the Coandă effect to entrain large volumes of surrounding air, dramatically increasing airflow while minimizing compressed air consumption. In many cases, they can increase airflow up to 25 times the supplied compressed air.

This means you can:

  • Move more air with less compressed air input
  • Reduce overall compressor load
  • Lower energy costs

For applications like ventilating enclosures, exhausting smoke or fumes, and cooling parts, air amplifiers can often replace inefficient open pipe blow offs or multiple air jets.

Super Air Knives: Efficient Blowoff for Drying and Cleaning

Blow off is one of the most common—and most wasteful—uses of compressed air. Many facilities still rely on drilled pipe or open copper tubing, which wastes enormous amounts of compressed air while generating excessive noise.

Super Air Knives create a laminar sheet of high-velocity air across the entire length of the knife. This provides powerful and uniform blow off while using significantly less compressed air than traditional methods.

Benefits include:

  • Reduced compressed air consumption
  • Uniform drying and cleaning
  • Low noise operation
  • No moving parts and minimal maintenance

Applications range from removing water after washing processes to blowing debris off conveyors, sheets, or molded parts.

Efficiency in compressed air usage isn’t just about saving energy—it’s about improving productivity, reliability, and process performance. When you replace inefficient air practices with engineered solutions, you often gain benefits across the entire operation.

If you’re looking to reduce compressed air waste or improve a blow off, cooling, or static problem, the right air tool may be a small investment with a big return.

And in many cases, it’s an investment that pays for itself.

The Hierarchy of Controls and How It Applies to EXAIR Compressed Air Solutions

Published on by Jordan T ShouseLeave a comment

In industrial environments, safety teams rely on the Hierarchy of Controls to reduce workplace hazards. Rather than relying on personal protective equipment (PPE), this process prioritizes eliminating risks at their source or engineering them out of the process. For manufacturers, maintenance teams, and engineers, applying the hierarchy of controls can significantly improve safety, reduce downtime, and increase efficiency.

Many compressed air applications—blow off, cooling, conveying, and static elimination—present opportunities to implement safer and more effective solutions using products from EXAIR.

What Is the Hierarchy of Controls?

The Hierarchy of Controls is a widely accepted framework in occupational safety used to minimize or eliminate exposure to hazards. It is commonly promoted by organizations like the Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health.

The hierarchy ranks safety controls from most effective to least effective:

  1. Elimination – Remove the hazard entirely
  2. Substitution – Replace the hazard with a safer alternative
  3. Engineering Controls – Isolate people from the hazard
  4. Administrative Controls – Change the way people work
  5. Personal Protective Equipment (PPE) – Protect the worker with gear

While elimination and substitution are ideal, they are not always feasible in manufacturing environments.

Applying the Hierarchy of Controls to Compressed Air Systems

1. Elimination

The most effective control is removing the hazard entirely. In compressed air systems, this can mean eliminating unsafe blow-off methods like open pipes or drilled tubing that create excessive noise, dangerous dead-end pressure, and flying debris. Replacing these setups with engineered solutions from EXAIR Corporation removes many of these hazards while maintaining performance.

2. Substitution

Substitution replaces hazardous equipment or processes with safer alternatives. In many facilities, this involves switching from improvised blow-off devices to engineered products like air nozzles or air knives. These solutions reduce noise, improve airflow efficiency, and significantly lower compressed air consumption.

3. Engineering Controls

Engineering controls isolate workers from hazards through equipment design. Many EXAIR products function as engineering controls by improving safety and reliability in compressed air systems. Devices like safety air nozzles, cabinet coolers, and air knives help control airflow, reduce noise levels, and prevent unsafe pressure conditions.

4. Administrative Controls

Administrative controls focus on improving procedures and training. This includes compressed air safety training, pressure guidelines, and routine system audits. While helpful, these controls rely on human behavior, so they are most effective when combined with engineered solutions.

5. Personal Protective Equipment (PPE)

PPE—such as safety glasses or hearing protection—is the last line of defense. It protects workers from hazards but does not remove the risk itself. Implementing engineered compressed air solutions can reduce many hazards before PPE becomes necessary.

Compressed air is one of the most widely used utilities in manufacturing—but it’s also one of the most misused. Improper blow off setups, excessive noise, and inefficient airflow can introduce safety hazards and energy waste.

With the right approach and the right equipment, companies can create safer, quieter, and more efficient processes—while maximizing the performance of their compressed air systems.

Solutions from EXAIR, help organizations move up the hierarchy by replacing unsafe methods with engineered products designed specifically for industrial environments.

How the Coanda Profile Drives Efficiency in EXAIR Products

Published on by Jordan T ShouseLeave a comment

In compressed air applications, efficiency often comes down to how effectively you use the air you already have. One of the most important aerodynamic principles that allows modern air-powered devices to operate efficiently is the Coanda Effect. This phenomenon is the foundation behind several EXAIR engineered products, enabling powerful airflow while minimizing compressed air consumption.

Understanding how the Coanda profile works can help engineers and plant managers optimize processes such as drying, cooling, cleaning, and conveying.

Compressed air flows through the inlet (1) to the Full Flow (left) or Standard (right) Air Knife, into the internal plenum. It then discharges through a thin gap (2), adhering to the Coanda profile (3) which directs it down the face of the Air Knife. The precision engineered & finished surfaces optimize entrainment of air (4) from the surrounding environment.

What Is the Coanda Effect?

The Coanda Effect describes the tendency of a fluid stream—such as air—to follow along a nearby curved surface instead of continuing in a straight line. As the air travels along this surface, it pulls surrounding air into the stream, creating a region of low pressure and dramatically increasing total airflow.

In simple terms:

  1. Compressed air exits a small opening.
  2. The air adheres to a curved surface (the Coanda profile).
  3. This creates a low-pressure area.
  4. Surrounding air is entrained, or pulled into the airflow.

The result is a much larger volume of moving air than the compressed air supply alone would create.

This principle was originally studied by aeronautical engineer Henri Coandă in the early 1900s while researching airflow over aircraft surfaces.

EXAIR Products That Use the Coanda Profile

EXAIR incorporates this aerodynamic design into several of its Intelligent Compressed Air Products™.

1. Air Knives

EXAIR Air Knives use a Coanda profile to create a wide, high-velocity sheet of air across the entire length of the unit.

Examples include:

  • EXAIR Standard Air Knife
  • EXAIR Full-Flow Air Knife
  • EXAIR Super Air Knife

Inside these units, compressed air enters a plenum chamber and exits through a narrow slot. The air then follows the curved Coanda surface, turning approximately 90° and flowing down the face of the knife.

As the air moves along the profile, it entrains large volumes of surrounding air—up to 30-40 parts ambient air for every 1 part of compressed air.

Common applications include:

  • Parts drying after washing
  • Conveyor cleaning
  • Web or sheet drying
  • Cooling components
  • Pre-paint blowoff

2. Air Amplifiers

Another product that relies heavily on the Coanda profile is the Air amplifier.

Super Air Amplifier Family

Example:

  • EXAIR Super Air Amplifier
  • EXAIR Adjustable Air Amplifier

Instead of producing a flat airflow like an air knife, air amplifiers generate a conical air stream. Compressed air flows across a circular Coanda profile that draws in large amounts of surrounding air.

This creates amplification ratios up to 25:1, meaning the airflow produced is far greater than the compressed air supplied.

Typical uses include:

  • Cooling hot parts
  • Ventilating smoke or fumes
  • Circulating air in enclosures
  • Removing heat from equipment

3. Air Wipes

EXAIR also applies the Coanda profile in a circular configuration for drying or cleaning cylindrical materials.

Super (left) and Standard (right) Air Wipes come in sizes from 1/2″ to 11″.

Example:

  • EXAIR Air Wipe
  • EXAIR Super Air Wipe

These devices create a 360-degree ring of air that surrounds rods, tubes, wires, or cables. As air follows the Coanda profile around the ring, it entrains surrounding air and produces a strong, uniform drying or blowoff action.

Applications include:

  • Drying wire or cable
  • Removing coolant from tubing
  • Cleaning rods or extrusions

The Coanda Effect might seem like a theoretical concept, but it has a very practical impact on industrial operations. By carefully designing curved surfaces that guide airflow and entrain surrounding air, EXAIR products turn a small supply of compressed air into a powerful and efficient airflow solution.

Whether drying parts, cooling electronics, or removing debris from a conveyor, the Coanda profile allows EXAIR products to deliver maximum performance with minimal energy use.
