Shade-Tree Mechanics and EXAIR Products

EXAIR most often sells business to business, but we also sell to individuals who need the right tools for their home projects.

If you frequent our blog it is no secret that I tend to have projects going on outside of work and I generally find a reason to have an EXAIR product when I am doing them. The first EXAIR application I had at home was in fact utilizing an E-Vac to build a motorcycle brake bleeder.  I still use that to this day, it is on my bench ready to help me rebuild my rear brake system on my bike once I decide to do it. I’ve blogged about that before. The most recent application I had was working on an early 1970’s Jeep with a close friend. He inherited the Jeep from his dad who no longer wanted to work on it. The Jeep hadn’t run in over a year and the original reason for parking it was ticking in the motor.

Broken parts removed – Time for cleaning.

Sure enough, once he got it up and running with some fresh gas and cleaning up the carb the tick had not gone away but he was able to narrow down that it was in fact coming from under the valve cover, so off it came.  We discovered that one of the bridges that hold down the valve rocker was broken, parts were ordered and we started cleaning everything off. The fix could all be had from right up top under the valve cover and should be easy enough once parts were in.  We cleaned up all the oil, removed all the bridges as well as the pushrods.

When we were removing the bolts from the valve cover and bridges there was a good amount of “sludge” and debris around the bolt holes.  When cleaning this all up some did go into the holes and we really wanted to try and keep all debris up top rather than going down into the motor. We noticed some crud around the top of the pushrod holes so we waited until we could use an Atto Back Blow Nozzle on a VariBlast Compact Safety Air Gun to pass down through the pushrod holes and effectively blow any and all debris back up to the top of the motor.  We also were able to use it on the blind holes of the bridge bolts and remove any fines or buildup that had fallen into the hole.

Cleaned up and ready for reassembly

After we were done cleaning up it was time to reinstall with the new part and having a clean top end made the job that much easier. Buttoned everything up, did an oil change, and then the Jeep fired right up with no ticking noise in the motor. Now he just has to clean up some wiring and get tags to put this classic back on the road.

Having the right tool for the job is always the best solution. Whether you are working on a car at home, or if you are career certified mechanic in a shop, the same goes across any industry. When using compressed air in an application EXAIR is the company that can supply you with the right tool to get the job done efficiently, safely, and quickly.

If you would like to discuss any point of use compressed air application, please contact an Application Engineer.

Video Blog: How-To Replace The Super Air Scraper Blade

The EXAIR Soft Grip Super Air Scraper is a great tool for any industrial environment that requires some cleanup. Some examples include removing tapes or sticky metal chips from the floor, scraping material from screening towers or removing stubborn adhesives and labels from workstation tabletops. They are available with extensions up to 72″ so reaching remote areas is also easier.

Today’s video is going to showcase how easy it is to replace the scraper blade within the nozzle and get back to work quickly.

If you would like to discuss how the Super Air Scraper could benefit your facility, contact us.

Chip Shields, OSHA, And You

Safety is a key part of our culture at EXAIR Corporation.  We have regularly scheduled, all-hands required, safety training on a number of topics.  Our Order Entry team can likely tell you as much about our lockout/tagout procedures as our Machinists can.  Nobody even thinks about entering The Shop without safety glasses, and it’s not just because of the signs.

We pay attention to these…
…so we don’t ever have to use this.

OSHA 1910.242(b) states that “Compressed air shall not be used for cleaning purposes except where reduced to less than 30 p.s.i. and then only with effective chip guarding and personal protective equipment. (emphasis mine)  All EXAIR Intelligent Compressed Air Products are engineered to meet the requirements of the first part (30psi outlet pressure to prevent dead ending…we’ve written about that numerous times, including here, here, and here) and we can also provide pre-installed devices to satisfy the second part:  the EXAIR Chip Shield.

Any EXAIR VariBlast or Heavy Duty Safety Air Gun can come fitted with a Chip Shield, and any Soft Grip Safety Air Gun, except for those with Stay Set Hoses, can as well.  Safety Air Guns with Back Blow Nozzles automatically come with a Chip Shield. The principle is simple: a clear polycarbonate (so you can still see what you’re doing) round disc slips over a short (or long if you want) pipe extension between the gun & the nozzle.  It’s fitted with a rubber grommet so you can position it to where it’s most effective – sometimes that might be closer to the part being blown off; sometimes it may be back a little closer to the operator.

EXAIR Safety Air Guns are available, from stock, with Chip Shields.

If you already have an air gun that’s doing the job, you can easily add an EXAIR Chip Shield to it.  They’re made to fit a wide range of extension diameters, and can even come with the extension if you need it.  We also stock a number of adapter fittings; if you know what threads your air gun has (or if you can send us some photos) we can quickly & easily spec those out for you.

Convenient and inexpensive “thumb guns” with cross drilled nozzles (left) are compliant with the first part of OSHA 1910.242(b). Fitting one with an EXAIR Chip Shield (center) makes it compliant with the second part. A Model 1102 Mini Super Air Nozzle (right) makes it quiet & efficient.
We can provide a Chip Shield for most any device with a threaded fitting. I couldn’t find a way to re-use the non-OSHA-compliant nozzle that came with this gun (thank goodness.)
Another example of a larger air gun fitted with a more powerful cross drill nozzle (left) that can be made totally OSHA compliant with an EXAIR Chip Shield (center.) An EXAIR High Force Super Air Nozzle (right) keeps the power, while reducing noise level and compressed air consumption (right.)

Since 1983, EXAIR Corporation has been manufacturing quiet, safe, and efficient compressed air products for industry (emphasis mine.)  If you have concerns or questions about safety in regard to your compressed air use, call me.

VariBlast®Compact Safety Air Gun

EXAR’s VariBlast® Compact Safety Air Guns are small and lightweight air guns capable of handling the toughest of jobs. With its variable flow trigger being its greatest design feature, it can take on small jobs and even big ones! This means you can get different flow and force out of the same nozzle by just adjusting the amount you pull the trigger.

The VariBlast Safety Air Gun, when outfitted with an EXAIR nozzle is OSHA safe and CE compliant. 

VariBlast Safety Air Gun With Extension and Chip Shield

The VariBlast can also be customized by adding one of our many 1/8 NPT engineered air nozzles, a chip shield and even an extension pipe up to 72″ long.

The VariBlast is easy to rebuild, every wear item is available in the 902001 rebuild kit. These parts can be used to rebuild any VariBlast Compact Safety Air Gun that, through use, has become worn. See this video to see how easy it is to rebuild this gun, and make it feel brand new!

If you have questions about the VariBlast or to discuss any of the 15 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and one of our Application Engineers can help you.
