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.

The Soft Grip Super Air Scraper Easily Cleans Floors

Scrape off, and blow away, stubborn debris with the Soft Grip Super Air Scraper.

Have you ever tried to remove a sticky substance with a putty knife? You scrape and scrape, then stop to remove the loose material. Then start scraping again that same area which has material remaining. It can be very time-consuming. And, if the material is on the floor, it can ergonomically hurt your back and knees.

A subcontractor that worked for an automotive company contacted EXAIR for a solution. They needed a faster, better, and easier way to remove tape from the floor. Personally, I have been through many automotive plants, and they have everything marked with tape. They use different sorts of tape to mark pedestrian walkways, machine locations, and fork truck lanes. So, when a work area gets new equipment or altered for better workflow, the tape has to be removed. And since downtime affects productivity, the work has to be done quickly. Their current mode of operation was for the staff members to work on the floor with hand scrapers to remove the tape.

The answer to the subcontractor’s problem was the EXAIR Soft Grip Super Air Scraper. This product uses a nozzle that combines a scraping blade with our 2” Flat Super Air Nozzle. It uses the mechanical force of a blade with the force of compressed air to remove stubborn sticky materials. The corrosion-resistant steel scraper is robust and durable, and they can be easily sharpened or replaced when worn. To add flexibility to the Super Air Scraper, a shim set can be used to increase the blowing force. This combination of the nozzle and the scraper is an effective and powerful way to remove material with compressed air.

Soft Grip Super Air Scraper

To get pressurized air to this patent-pending nozzle, EXAIR attached the Super Air Scraper to our Soft Grip Air Gun. The Soft Grip Air Gun has an ergonomic soft handle and a full-grip trigger for hours of use without fatigue.   We include different extensions for hard-to-reach applications ranging from 6” (152mm) to 72” (1,829mm) in length. With extensions that are 36” (914mm) and longer, EXAIR installs an additional foam grip sleeve. This gives more leverage for scraping material at a distance like at the floor level. Chip Shields can also be added to prevent blow-back onto the users.

For the subcontractor above, this was the perfect tool for their next assignment. I recommended the model 1244-36 Soft Grip Super Air Scraper which had a great length to reach the floor and a foam grip to force the blade under the tape. With the compressed air, it helped to keep the area clean during scraping and aided with the tape that was really stuck. They ordered six pieces, one for each staff member, to work the entire area to remove tape. The subcontractor was able to cut his scraping time by 75% as compared to the putty knife method above. And the staff members appreciated the need to not get on the floor.

To give some other areas for the Soft Grip Super Air Scraper, they can be used for removing gasket material, caulk, adhesives, paint, labels, and much more. If you have a “sticky” situation at your facility, an Application Engineer at EXAIR will be happy to discuss it with you.

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.
