Beat the Heat: Why EXAIR Cabinet Coolers are the Ultimate Industrial Fix – (Cabinet Cooler Promo)

Published on by Al WooffittLeave a comment

As the mercury rises, industrial facilities face a familiar foe: heat-related downtime. When sensitive electronics and control panels overheat, production grinds to a halt—often at the most inconvenient times. While fans or traditional air conditioners might seem like the go-to solutions, they often bring their own headaches, like clogged filters or mechanical failures.

Enter EXAIR Cabinet Cooler Systems, a low-cost and highly reliable alternative that uses nothing but compressed air to keep your critical components running cool and clean. And now through the end of August, with the purchase of these systems, you will receive a free AC Sensor — Model 7929.

How They Work: The Power of the Vortex

At the heart of every EXAIR Cabinet Cooler is a Vortex Tube. This clever piece of engineering converts a standard supply of compressed air into two streams: one hot and one cold.

  • Cold Air Injection: The cold air is discharged directly into the cabinet through a distribution kit, creating a pressurized environment.
  • Contaminant Exclusion: Because the cabinet is slightly pressurized, outside air—along with its dust, dirt, and oil—can never get in.
  • Heat Exhaust: The warm air inside the cabinet is displaced and vented out through the cooler body, leaving your electronics in a clean, temperature-controlled environment.

Maintenance-Free Reliability

One of the biggest advantages of EXAIR’s design is what it doesn’t have. There are no moving parts to wear out, no filters to clog, and no refrigerants (like Freon) to leak.

  • Simple Installation: These units can be installed in minutes through a standard electrical knockout.
  • Long Lifespan: With a clean, dry supply of compressed air, these coolers can run for decades—some have even been tested to work perfectly after 20 years of service.

Smart Cooling with Thermostat Control

While the coolers are incredibly effective, using compressed air continuously can be expensive. To maximize efficiency, most systems include a Thermostat Control.

  • Automated Operation: The thermostat (factory set at 95°F) acts as an on/off switch, activating the cooler only when the temperature reaches critical levels.
  • Digital Precision: For even tighter control, Electronic Temperature Controls (ETC) are available to maintain a constant temperature with a digital LED display.

A Solution for Every Environment

No two facilities are the same, which is why EXAIR offers several ratings to match your specific needs:

  • NEMA 12 (IP54): For dust-tight, oil-tight indoor industrial environments.
  • NEMA 4 (IP66): For splash-resistant indoor or outdoor use.
  • NEMA 4X: Corrosion-resistant 303 or 316 stainless steel for food service or aggressive chemical settings.
  • Hazardous Locations (HazLoc/ATEX): Specifically designed and certified for explosive environments containing gases or dust.
  • High Temperature Models: Capable of providing relief in ambient temperatures reaching up to 200°F (93°C).
Both the HazLoc (left) and ATEX Cabinet Cooler Systems are available from stock in NEMA 4 and NEMA 4X ratings.

Stop the Shutdowns

Don’t wait for a 100°F day to realize your cooling is insufficient. You can use the Cabinet Cooler System Calculator on EXAIR’s website to find the exact cooling capacity you need, with models ranging from 275 to 5,600 Btu/hr.

The Power of Precision: Why EXAIR’s Adjustable E-Vac is a Game Changer

Published on by Al WooffittLeave a comment

When designing a vacuum system, the “one-size-fits-all” approach rarely works. EXAIR offers two primary types of single-stage vacuum generators: the In-Line E-Vac and the Adjustable E-Vac. While both use a venturi design to create instantaneous vacuum without moving parts, choosing between them depends on how much control and “forgiveness” your application requires.

The primary difference lies in versatility and internal geometry. In-Line E-Vacs are compact, cylindrical units designed for specific, unchanging tasks.

  • Variants: They come in “High Vacuum” models for non-porous materials (like glass or steel) and “Low Vacuum” models for porous materials (like cardboard).
  • Limitation: Once you choose a model, its performance is fixed.

Adjustable E-Vacs allow you to “dial in” the exact vacuum level and flow rate needed.

  • Versatility: By loosening a locknut and turning the exhaust, you can shift the unit’s performance to handle different weights or surface porosities.
  • Durability: They feature a much larger throat diameter, which allows them to pass small solids, dust, and even liquids without clogging.

The Choice: Why Go Adjustable?

The Adjustable E-Vac is the superior choice when your production line handles either variety, or potentially contains contamination. For facilities that use a robotic arm to pick and place various items from a conveyor depending on the job, you would potentially need more than one style of In-Line E-Vac. For example, if one job requires lifting heavy, non-porous plastic containers, you would need a high-vacuum, low-flow unit; whereas if the next job is handling lightweight, porous cardboard boxes, this would require a low-vaccum, high-flow unit.

By choosing the Adjustable E-Vac, you can tune for porosity: Increase the vacuum flow with a quick adjustment to overcome the “leakage” inherent in cardboard. In addition to this, if the surface is less than pristine, the larger throat diameter will have no trouble passing the dirt and debris.

If you’re ready to integrate these tools, several kits and individual units are available:

  • EXAIR Adjustable E-Vac Vacuum Generator 840008: A compact 8 SCFM model, ideal for smaller pick-and-place tasks.
  • EXAIR Adjustable E-Vac Vacuum Generator 840015: A mid-range 15 SCFM unit for higher flow requirements.
  • EXAIR E-Vac Adjustable Vacuum Generator Deluxe Kit 842030: A complete solution including the pump, an assortment of vacuum cups, tubing, a filter separator, and a pressure regulator.
  • EXAIR E-Vac Deluxe Kit 842060M: A high-capacity 62.7 SCFM kit featuring a straight-through muffler, perfect for environments with heavy particulate.

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.
