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.

Adjustable Air Amplifiers: Product Overview

Published on by John BallLeave a comment
Adjustable Air Amplifier

EXAIR manufactures two types of Air Amplifiers: Super Air Amplifier™ and Adjustable Air Amplifier™.  The Air Amplifiers can be used to cool, dry, clean, ventilate, exhaust and many other uses.  In this blog, I will focus on the features and benefits of the Adjustable Air Amplifiers.

The main difference between the Super Air Amplifier and the Adjustable Air Amplifier is the fact the Super Air Amplifier has a shim inside of it that sets the gap for the air flow.  Force and flow for the Adjustable Air Amplifier is changed by turning the exhaust plug with a pin wrench.  This will open or close the gap inside, changing the amount of vacuum and air flow.  When the desired performance has been found, we have a knurled lock ring to hold the flow at the desired level. This is great for changing environments where needs are regulated to different conditions.

The Adjustable Air Amplifiers come in either 303 Stainless Steel or Aluminum and are sized from ¾” to 4”.  We offer them in a kit which will add a filter separator and a pressure regulator to the mix.  The filter will clean the compressed air, and the regulator will control the amount of pressure to enable you to “dial it in”, so to say.  We also have a deluxe kit which will add another item, Electronic Flow Control, or EFC.  This unit has a photo-electric eye to control a timing circuit to turn on and off the Adjustable Air Amplifier.  This helps to save on compressed air usage. 

The maximum temperature rating for the Aluminum Adjustable Air Amplifier is 275oF (135oC) while the stainless-steel version is rated up to a maximum of 400oF (204oC).  The stainless steel version is also used for chemical resistance and food applications. 

They do not have any moving parts, so they will last a long time and require no maintenance. Since they do not employ a motor, they create a laminar airstream which makes them effective and quiet.  They use a Coanda profile to generate a low pressure on one side to entrain a large volume of ambient air along with the primary, compressed air flow.  The Air Amplifiers amplify the exhaust air up to 24:1, making them very efficient for the compressed air used to create the output flow.  They are designed to have hoses attached to the discharge or suction side if you wish to move the air to or from another location. 

EXAIR has many uses worldwide where our Air Amplifiers are being used.  If you have any questions or would like to discuss your application, you can contact the Application Engineers at EXAIR.  We would be happy to help.

Chip Trapper: Take Back Control of Your Coolant, and Your Productivity

Published on by Neal RakerLeave a comment

If you work with CNC machines, lathes, or other equipment that uses coolant or cutting fluids, you already know the headache that comes with chip‑laden, contaminated liquid. Floating debris, sludge, and swarf don’t just affect coolant life—they cause machine downtime, poor finishes, pump damage, and unnecessary costs.

The EXAIR Chip Trapper™ and High Lift Chip Trapper™ are designed to eliminate these problems quickly, safely, and without the mess or maintenance headaches of traditional pump or electric vac systems. Here’s how this powerful solution helps you reclaim time, money, and consistency on your shop floor.

Clean Your Coolant—Fast and Without the Mess

The Chip Trapper uses EXAIR’s Reversible Drum Vac, a simple but powerful two‑way pump that quickly vacuums contaminated coolant into a standard 55‑gallon drum. As the liquid enters the drum, it’s forced through a durable, reusable filter bag that traps chips and debris before the clean liquid is pumped back out.

How this benefits you:

  • Cuts coolant replacement costs by removing chips instead of throwing away usable fluid.
  • Prevents pump failures caused by recirculating metal chips and fines.
  • Reduces machine downtime—you can restore coolant clarity in minutes instead of hours.
  • Improves machining performance by keeping cutting fluid clean and flowing as intended.
  • You have options – You can pick what level of filtration that you want to achieve from 1 micron to 200 microns with additional, replacement filter bags. Systems come standard with 5-micron filtration.

Built for Real Shop Conditions

Your environment is demanding, so the equipment has to be too. The Chip Trapper is engineered for durability, reliability, and easy operation in any industrial setting.

Key features your team will appreciate:

  • Runs on compressed air—no electric motor, no moving parts to fail.
  • Works with your existing shop air up to 100 PSIG, with a maximum of 120 PSIG.
  • Designed for years of maintenance‑free performance when used with clean, filtered air.
  • Automatic safety shutoff prevents messy overfilling.
  • Quick‑change filter bags make maintenance simple and efficient—no tools required.

Because the system has no electrically driven parts, it’s not only safer—it avoids the clogs, burnout, and unreliability of conventional electric pumps.

Easy Operation: Vacuum In, Pump Out

Using the Chip Trapper is refreshingly simple:

  1. Connect compressed air using the manual shutoff valve.
  2. Attach the vacuum hose and chip wand to pull liquid and debris from your sump.
  3. Set the directional valve to FILL to vacuum dirty liquid.
  4. Set the valve to EMPTY to pump back out filtered, clean coolant.

Most users love that the process is clean, fast, and nearly foolproof—no dealing with clogged pumps or slow draining.

Handles Even Tough Applications

The Chip Trapper isn’t just for coolant recycling—it’s an incredibly versatile cleanup tool.

Great for:

  • CNC sump cleaning
  • Removing chips from settling tanks
  • Floor spill recovery (with optional Spill Recovery Kit Model 6901)
  • Deep sumps or long fluid runs (High Lift Chip Trapper models offer increased suction for these situations)

Whether you’re cleaning up after heavy machining or maintaining multiple machines, the Chip Trapper keeps your shop safer, cleaner, and more productive.

Low Maintenance, High Reliability

Maintenance is minimal and quick:

  • The safety shutoff float may occasionally need cleaning with mild solvent/detergent.
  • The stainless‑steel pump can be disassembled for deeper cleaning if needed.
  • Vacuum hose and attachments rinse clean after each use.

Because clean air is critical, EXAIR recommends a 10‑micron filter separator for the compressed air supply—when used properly, the unit will run for years without issue.

The Bottom Line: A Cleaner Shop and a Healthier Bottom Line

The Chip Trapper is more than a coolant-cleaning tool—it’s a reliability booster, money saver, and productivity enhancer.

Customers typically see:

  • Significantly longer coolant life
  • Better machine performance
  • Reduced labor time for sump cleaning
  • Lower maintenance costs
  • A safer, cleaner work environment

If your machines are struggling with chip buildup, cloudy coolant, or recurring sump issues, the Chip Trapper is one of the simplest, most cost‑effective upgrades you can make for these processes.
