EXAIR‘s line of Industrial Housekeeping Products consist of liquid and dry vacuums that utilize compressed air to operate. They do not have electric motors which most ‘all purpose’ vacuums rely on. In industrial settings with harsh conditions and rugged use, EXAIR’s Industrial Housekeeping Products are ideally suited for the everyday wear and tear.
There are no motors and bearings to wear out and no impellers to clog. The Chip Vac is 50% quieter than a comparable electric vacuum. Safety is a top priority, and the use of the unit on wet floors and spills is not an issue when electricity is not involved.

Last week, I wrote about the benefits and advantages of the EXAIR Chip Trapper System. It’s just one workhorse in our stable of durable and reliable compressed air operated Industrial Housekeeping solutions. All of our systems in this product line are compressed air operated, which means they offer several benefits that you don’t get with an electric powered vacuum:
Our air operated vacuums have no moving parts. That means nothing to wear out & replace.
Electric motors burn out over time, and have to be replaced. Not a problem with our products…if you supply them with clean air, they’ll run darn near indefinitely, maintenance free.
Using electric vacuums in wet areas can prevent a very real risk of electrocution. This hazard does not apply to a compressed air hose, which is all it takes to run our products.
Long, stringy chips can get clogged in the impeller & rotating parts of a motor-driven vacuum. Ours have no moving parts, which means nothing for detritus to get tangled up in.
Which EXAIR Industrial Housekeeping Product is right for you? It depends on what you’ll be using it for. Very generally speaking, here’s a brief overview of the product line:
Pick up dry or wet chips and transfer them into a standard open top drum.
Available in four sizes: 5, 30, 55, or 110 gallon drums.
Turns your own 30, 55, or 110 gallon open top drum into a powerful vacuum system, in minutes, with a standard system.
Add portability and flexibility with a Deluxe System, which includes a drum dolly and a Tool Holder.
For a total Industrial Vacuum System, complete & ready to go right out of the box, the Premium Systems add a drum, a compressed air supply hose, an upgrade to Heavy Duty Aluminum Tools & a Static Resistant Vacuum Hose.
For smaller jobs or in tight quarters, the Mini Chip Vac System comes with a compact 5 gallon drum. The Deluxe System adds a drum dolly for portability.
These are our drum mounted vacuums for liquids. They’ll fill or empty a 55 gallon drum in 90 seconds (tested with water.)
Fits an existing 30, 55, or 110 gallon closed top steel drum in good condition.
Deluxe Systems add a drum dolly, a Tool Holder and a set of plastic tools including a Spill Recovery Kit, for a multitude of cleanup needs.
Auto shutoff float prevents overfilling the drum.
Premium Systems add a 30, 55, or 110 gallon drum, Heavy Duty Aluminum Tools, and a compressed air supply hose.
High Lift Systems are available for higher viscosity (ups to 1400 cP) liquids, or when pumping from below grade (180″H2O suction lift.)
This same technology is incorporated into the Chip Trapper Systems, which (as detailed last week) trap incoming solids in a Filter Bag, allowing for instant pumping out of freshly filtered liquid. They’re available with the High Lift capability as well.
Handy and portable, the Vac-u-Gun is a lightweight handheld vacuum, blow gun, and transfer tool, all in one.
Collection System comes with a vacuum bag w/shoulder strap, extension wands, a crevice tool, skimmer tool, and round brush tool.
Transfer Systems come with the same tools, but include a 10ft hose instead of the vacuum bag.
All Purpose Systems come with the tools, the vacuum bag, and the 10ft hose.
Deep Hole Vac-u-Guns are fitted with a blow tube for stirring up fine debris from drilled holes, where it’s quickly and efficiently vacuumed away.
Regardless of your application, EXAIR has an Industrial Vacuum to fit. Orders for qualifying systems through the end of May 2020 will include a free Vac-u-Gun. If you’d like to discuss your Industrial Housekeeping needs, give me a call.

This past weekend in Columbus, OH was a sporting event hosted by Arnold Schwarzenegger. This event has many aspects of it and this past weekend was the first year where spectators were not permitted due to the COVID-19 risks and scares. The caterer for the event had already prepped all of the food to prepare for thousands of people so instead of donating locally, they connected with head chefs in Nashville, TN to create a “tailgate extravaganza” to try and lift the community up after the recent tornado and storms ravaged the area and demolished homes as well as communities. The Arnold still happened, with participants only, they were all, “Picking Things Up and Putting Them Down.”
Seeing these giant athletes perform deadlifts always reminds me of the EXAIR Adjustable E-Vacs and how they are used frequently to pick things up and put them down. When determining the correct Adjustable E-Vac I always like to start with the shape, weight, and surface of the part. This is how I determine which vacuum cup can be utilized. The good news is as a customer, the choice doesn’t have to be made alone, that is why the Application Engineering team is here, we’ll help you determine which vacuum cup will suit the given application.
Some of the factors we use to determine the suction cup is listed out below.
Is the lift going to be a vertical cup lift or a horizontal cup lift? This means is the face of the cup vertical, picking up a box from the ground by the sides, or is it going to be horizontal where the face of the cup sits horizontally over the part.
For a vertical cup face, if lifting the part up vertically then a bellows cup will not be suitable and something with a cleat will be needed due to the rigidity of the cup to help keep the cup and part stable. The bellows may collapse due to the weight of the product, where the cleats will interface with the part and create a solid connection to aid in the lift.
For a horizontal cup face, if lifting the part up vertically then a bellows cup would work ideal in the event the surface is uneven. Maybe one end is slightly taller, in this scenario, a bellows cup would help the cups to all seal to the surface and still be able to pick up the item. These cups are also thinner to help adapt to an irregular surface on the part or to help keep suction if the part deforms upon being picked up. The bellows is not recommended for rather heavy objects as the bellows may collapse under extensive load and cause the cup to lose suction.
Talking about the weight of the item, this also becomes a major factor as each cup has a maximum lifting weight and that is determined by the surface area of the cup as well as whether it has cleats, bellows, or just a plain cup. Our goal when sizing the cups to the parts is to ensure they are going to engage the surface in a solid secure manner that makes the lifting rig safe and stable to use.
For example, take a look at this solar lens manufacturer who utilizes many EXAIR products in this pick and place operation.

Our E-Vac Vacuum Generators are probably most commonly used in pick-and-place applications, in conjunction with our Vacuum Cups.
The Adjustable E-Vacs, however, have a unique feature – a relatively large throat diameter – that makes them well suited for suctioning up liquids. And I recently had the pleasure of helping a caller with just such an application. They make machinery for the automotive industry, and in one particular operation, coolant gets left behind in ‘pockets’ of a particularly unwieldy piece. They can drain most of it at the machine, but what gets left behind in these pockets makes a real mess as it goes to the next fabrication point, and, although it’s a small amount in each pocket, it adds up to a finite amount of wasted coolant. It’s not practical to use an electric shop vacuum, but an operator could easily use a handheld device to suck up these little puddles.
Enter the Adjustable E-Vac…with the wide throat diameter I mentioned above and compact design, they were able to install a short suction hose (via a threaded push-in connector) to the vacuum port, and a little longer discharge hose to the exhaust port, and they have a quick and easy, portable, maneuverable coolant transfer system. Here’s a short video I made in the Demo Room, once upon a time, showing how it works:
Saving air. Saving coolant. Saving money and time, one compressed air application at a time. If you have one you’d like to discuss, give me a call.

In 1797 a Italian physicist named Giovanni Battista Venturi wrote a dissertation on the “Venturi Effect”. However, an actual device was never created or applied until 1888 where Clemens Herschel was awarded the patent for the first Venturi tube.
The Venturi effect is a decrease in fluid pressure when fluid flows through a constricted area of a pipe. In other words, as the diameter becomes smaller, the fluid velocity becomes faster. This increase in velocity will create a lower pressure just past the constricted area. When designed correctly, you can create a strong vacuum or a large negative pressure.
The EXAIR E-Vac® Vacuum Generators use this phenomenon by using compressed air as the fluid. This type of Venturi tube restricts the internal area to generate a fast velocity through the body creating a vacuum pressure for suction.
EXAIR offers three types of Venturi tubes; low vacuum, high vacuum and adjustable. Low vacuum units are typically used with porous material because the trade off for low vacuum is higher vacuum flow. The high vacuum generators can create a vacuum level as high as 27” Hg (71 KPa). The Adjustable E-Vacs can alter the internal air velocities by turning the body and getting different vacuum pressures. Without any moving parts or electric motors to break, the EXAIR E-Vacs are a simple design that is very durable, effective and long-lasting. A great product for applications like pick and place, clamping, lifting and vacuum forming.
The Venturi effect was discovered in 1797, brought into existence in 1888, and is still used in vacuum applications to this very day. If you have an application where a Venturi tube could help you, please contact an Application Engineer. We will be happy to assist you.
Getting a vacuum from compressed air seems a bit like magic, but it works and it works well. EXAIR’sE-Vac® Vacuum Generators are compressed air powered, single stage vacuum generators. They are a low cost way to create vacuum for pick and place, clamping, lifting, chucking, vacuum forming and other applications.
The Low Vacuum Generators are ideal for ‘porous’ types of applications. When we say ‘porous’ we are describing those processes where a lighter vacuum level combined with higher vacuum flows are needed. A good example of this is lifting a cardboard box. The cardboard is not air tight, and when you place a vacuum on it, air is able to be pulled through the cardboard. To maintain the vacuum level, the air needs to be able to be pulled through the cardboard and exhausted as fast as it is being pulled through in order to maintain the vacuum level. This requires higher vacuum flow and the design of the Low Vacuum Generator allows for the development of a good vacuum level and a high rate of vacuum flow.
The High Vacuum Generator is ideal for ‘non-porous’ type of applications. ‘Non-porous’ are those processes where the material is air tight, and no or very little air can pass through. Material such as glass, ceramic, and steel are ‘non-porous’. Because little or no air passes through, the need for high vacuum flow is not as important, and the highest of vacuum level can be achieved. A perfect vacuum is 29.92 in-Hg, and the High Vacuum Generator is designed to reach vacuum levels of 27 in-Hg, or a 90% vacuum level.

Both the Low Vacuum and High Vacuum Generators come in 7 different sizes, ranging from light to very strong vacuum capabilities, to match any application. Special Kits are available as a way to experiment with an assortment of vacuum cups to determine the best configuration.
And for maximum flexibility, EXAIR offers the Adjustable E-Vac Vacuum Generator. Engineered for high efficiency, compressed air can be minimized due to the ability to adjust and tune the vacuum flow and level to perfectly match the application requirements.

In my last blog, I went over How to Choose/Build an E-Vac system, and you can read about that here– The E-Vac’s are a compressed air powered, single stage vacuum generator, providing a low cost solution for creating a vacuum for many applications. Today, we will look at the many accessories that are available to complete a vacuum system best suited to your vacuum application.
For pick and place operations and hold down or clamping processes, we offer an array of Vacuum Cups. Available from stock are small and large Round, Oval, and Bellows styles. Round cups are best suited for smooth, flat surfaces. Oval cups provide the most vacuum due to the larger surface area, making them ideal for lifting heavy loads. The Bellows style is best suited for textured or uneven surfaces, where the folds provide a collapsible area that allows the cup to compress and seal to the uneven surface.
For vacuum processes where personnel are nearby, there are two (2) types of mufflers available to reduce the sound level to comply with the limits OSHA Standard 29 CFR – 1910.95(a) has established. The EXAIR E-Vac Mufflers are designed so that the E-Vac exhaust is not impeded, so that the highest and fastest vacuum response is achieved. The Standard Muffler (for use with In-Line E-Vacs only) has a closed end and is best suited for vacuum draws that are free from dust and debris. The Straight Through Muffler is open all the way through and is recommended for those vacuum draws where there will be dirt and debris, since it will not plug up. The Straight Through style offers the best sound level reduction, up to 26 dBA.
The vacuum port of the E-Vacs has an NPT threaded connection and with a suitable connector, a vacuum cup can be closely installed, minimizing the system air volume. When vacuum cups are to be remotely mounted, Push-In Connector Type Fittings of assorted styles are available along with the polyurethane tubing to make the installation and vacuum plumbing a cinch.
And finally, to get the best performance and maintenance free operation from your E-Vac, always use a source of clean, dry compressed air. We can help you do that with a wide array of Automatic Drain Filter Separators and Oil Removal Filters sized to pair up with the various E-Vac’s. Also available are Pressure Regulators, Vacuum Gauges, Manual Shut Off Valves, Solenoid Valves, and Compressed Air Hose.
