Take It All In – Just Filter It

The Nose – Only the Nose Knows

Take a nice deep breath as you read this. In through the nose. If you are like me right now, due to Fall allergies you’ll have a little bit of a restriction, hold it for just a second and then breathe out through the mouth. The body is an amazing thing, when we breathe in through our nose the body has some natural filtration built in that is also known as nose hair. While not the most attractive thing to most, it is important. The hairs in the nose help to filter out allergens and catch foreign debris.

An Improperly maintained Cabin Air Filter on a car makes a great bed for mice

Other items you interact with daily have similar air intake filtration. A car often has both an intake air filter and even an in-cabin air filter, these both protect various parts. The engine air filter is vital to prevent dust, debris and even excessive water from entering into the precision machined and assembled motor. The HVAC system in every business or home generally has an intake air filter in order to protect the coils and heater box.

There’s another system in most manufacturing facilities that should always have a filter on it, and that is the compressed air system. Properly maintaining and filtering the incoming ambient air feed before it is compressed starts the process of on the right foot to optimize performance and insure efficiency is maintained from the start of the entire process. These filters are like many others and can be part of a preventative maintenance program. The air compressor manufacturer will have a recommendation on frequency for the various types.

Old Piston driven air compressor intake air filter.

If these filters are left unchanged then the compressor begins to have restricted flow on the intake which then results in less air being pulled in or maybe the filter is removed and then the debris all gets pulled in and sent through to become foreign debris inside the compressor. Both of these will cause the compressor to wear or overheat and work harder to compress the air and send it into the storage tank. This results in premature maintenance needed on the compressors and or point of use devices.

Thus, always filter your incoming air. Whether for your air compressor, car engine, or house, start with a fresh intake and then keep it optimized from there. The payback will be longer lasting equipment that operates at a higher efficiency. And remember, breathe in through your nose.

If you would like to discuss your filtration setups, feel free to reach out to an Application Engineer.

More And More Award Winning Products From EXAIR

As you might expect, a LOT of things have changed at EXAIR Corporation since 1983. Most of our current senior management had yet to graduate high school, and a fair number of current employees had yet to BE BORN. According to our computer system (another BIG change since 1983), our first ten customers were here in southwest Ohio (#11 was in Michigan), and now, we sell direct across the US & Canada, and our worldwide distributor network offers representation on six continents. One thing that hasn’t changed, though, is our founder’s vision of manufacturing quiet, safe, & efficient compressed air products for process improvement in just about any industry that uses compressed air. And THAT, dear reader, continues to gain high profile attention. The photo above shows the seven awards that our products have recently won, which were announced in 2021 or early 2022. Here’s a rundown:

Machine Design 2021 Big Idea! (Electrical Components) BRONZE AWARD
Gen4® Static Eliminator Power Supply

All EXAIR Gen4 Static Eliminators use one of two Power Supplies – your choice of the 2-port Model 7960, or the 4-port Model 7961.

EXAIR Static Eliminators produce ionized air via a Corona discharge, which requires high voltage, low current electricity. The Gen4® Static Eliminator Products feature armored & shielded cables with an internal ground, for safety and reliability. The ground path is completed through the cable and the Power Supply port, eliminating the need for an external ground connection. Faults in external ground connections result in the majority of the problems with those devices, so the internal ground is a “Big Idea!” indeed. The Gen4® Static Eliminator Power Supplies are switchable for 115VAC or 230VAC voltages, and are offered in 2, or 4 outlet designs, which can power any 2, or 4 EXAIR Static Eliminator Products. Like most EXAIR Intelligent Compressed Air Products, they’re used for a wide range of applications, in a wide range of industries:

Super Blast Safety Air Gun Improves Cleanup Process

I had the pleasure of helping a caller out with a cleanup problem not long ago.  Normally, calls involving cleanups involve a discussion of how our Industrial Housekeeping Products might replace an electric shop vacuum or sump pump, but this one was about replacing a broom…with a Super Blast Safety Air Gun.

Now, I need to mention that the folks at Compressed Air Challenge have a list of Inappropriate Uses Of Compressed Air.  Using compressed air for cleaning is on that list, and I couldn’t agree more…as a blanket statement, that is.  Of course, the last paragraph of their document makes it clear that good judgement can, and should, always rule the day: “if safety enhancements, significant productivity gains, or labor reductions will result,” they say, a compressed air solution is certainly worth considering.

That’s exactly what the caller and I did.

See, he works in an equipment service shop.  Their technicians make the company money through billable labor – the time they spend fixing their customers’ equipment.  Of course, they have to spend time on tasks that aren’t billable to jobs…like tool maintenance, paperwork, and keeping a clean shop.  A particular item from a shop audit that caught his attention was the amount of time spent sweeping the floor in the welding area.  Not only did slag & dust get all over the floor out in the open, it accumulated under tables and behind the welding machines themselves.  This meant that technicians had to get down on their hands & knees, and reach brooms under those tables.  Not only was this cumbersome; it wasn’t even 100% effective…when replacing a machine recently, they discovered a surprising amount of debris in a “blind spot” that the broom just couldn’t reach.

After a discussion of the engineered Super Air Nozzles that are available on the Super Blast Safety Air Guns, the caller liked the idea of the Model 1213-7-3.  The hard hitting, tight air flow pattern of the Super Air Nozzle Cluster at the end of a 3 foot extension gave the perfect combination of power & reach for his application.

Super Blast Safety Air Gun makes short work of large area cleanup.

So, at the end of the day, (literally…that’s cleanup time, right?) a task that previously took about 10 minutes for them was reduced to just under two minutes.  Of course, that doesn’t figure in the cost of the compressed air.  The Department of Energy uses a thumbrule that states it costs $0.25 to generate 1,000 Standard Cubic Feet of compressed air.  At 98 SCFM @80psig, the Super Blast Safety Air Gun’s Cluster DOES use a decent amount of compressed air, so we did the math:

98 SCFM X 2 minutes X $0.25/1,000 SCF =   $0.049

We didn’t need to get in to payroll records, employee benefit packages, etc., to realize that an 80% reduction in labor, improved cleanup (air reaches where the brooms couldn’t,) and worker satisfaction (no more crawling along the floor beside the tables) was worth a nickel a day.

The Super Blast Safety Air Gun can be fitted with a variety of Super Air Nozzles, from our Model 1112 3/4 NPT Super Air Nozzle (4.5lbf at 12″) , to our Model 1120 1-1/4 NPT Super Air Nozzle (23lbf at 12″).

As an Application Engineer, I’m always looking for the best ways to apply our products, and quantify the benefits.  If you call me to discuss an application and the math doesn’t prove it out, I’ll let you know.  If you have a task you’re considering a compressed air solution for, give me a call.

When To Use The High Lift Reversible Drum Vac vs. The Reversible Drum Vac

One of my favorite TV shows growing up was Home Improvement with Tim Allen. One of the most memorable parts of the show was when Tim’s character would always state that when doing a job you need … MORE POWER!!!

In real life and within a production environment this is not always true. More often than not more power equals waste and inefficient use of the resources at hand. I know, I sound a lot like Tim Allen’s counterpart in the show, Al Borland. Well, the truth is, Al was usually right.  Here at EXAIR, we offer two different types of Reversible Drum Vac, the standard unit and the High Lift RDV.

The Reversible Drum Vac System converts a drum and dolly into a mobile pumping system.

The standard RDV will pull up to 96″ of water column when in suction mode. This is ideal for water-soluble coolants or other water-based rinses. The unit is paired with a 10′ vacuum/discharge hose to ensure optimal performance. The RDV will fill a 55-gallon drum with water in 90 seconds or less when operated at 80 psig inlet pressure. It will then empty the same drum even faster by discharging liquid at up to 166″ of water column displacement. To do both of these operations, fill or empty the drum the RDV will utilize 19 SCFM of compressed air. This is easily supplied within most industrial applications where that amount of compressed air usage can be overlooked.

EXAIR’s High Lift RDV makes cleaning out pits up to 15′ deep easy and fast.

If Binford manufactured a compressed air liquid vacuum, it would be the High Lift Reversible Drum Vac. This is the, “More Power” version of the RDV and can pull up to 180″ of water column when in vacuum mode. This can pull water-soluble coolants up to 15 feet below grade for those large machining centers that sit over the top of a coolant pit or those large footprint machines where a 20′ hose is needed to reach into and around the parts of the machine to where the coolant or liquid is housed. Another application would be for oil-based coolants or other petroleum-based oils/higher viscosity fluids. This will still discharge liquids at 166″ of water column when in positive displacement. The unit will outperform its predecessor and that comes with higher utilization of compressed air. While operating at 80 psig inlet pressure the unit will consume 43 SCFM of compressed air. This volume of air is still easily located within most industrial environments and is still less than the amount demanded by competitive units that do not offer the reversible feature of the High Lift Reversible Drum Vacs.

When it boils down to it, the High Lift Reversible Drum Vac will perform every task of the standard Reversible Drum Vac and will perform the vacuum portion of those tasks all faster due to the higher level of vacuum. When this higher level of vacuum isn’t needed, when the sump is at ground level and the coolant or liquid is around the viscosity of 50 weight motor oil or thinner then the standard RDV will work ideal for the application and would be the most efficient method to get the job done. When the liquid is higher viscosity or below ground level trying to pull it up out of a pit then the High Lift Reversible Drum Vac is the ideal tool to get the job done. Again, Al Borland had it right, more power is not always needed, sometimes it is better to keep it efficient.

If you would like to discuss your liquid vacuum application or any point of use compressed air application, please contact us. (Heck, I’ll even talk about Home Improvement if you are a fan too.)
