EXAIR Chip Shield Sizes and Selection

EXAIR has many options when considering Air Nozzles, Air Jets and Safety Air Guns. When considering the safety in using these tools one should consider the extra protection that EXAIR Safety Shields offer. Let’s look at the options and sizes of our Chip Shields.

EXAIR Chip Shields are durable polycarbonate shields that can be used with or without extension pipes. The Chip Shield, as the name suggests, protects the operator from flying debris such as metal chips, shavings and liquid coolants. The use of Chip Shields help meet the requirements of OSHA 1910.242(b) for safe use of compressed air.

If you are ordering a new Safety Air Gun from EXAIR and need a Chip Shield you simply place a “-CS” after the Safety gun model number, For example if you order Model 1210 VariBlast Compact Safety Air Gun (SAG) and want a Chip Shield you would order Model 1210-CS and EXAIR will automatically know the size of the shield and will ship the Safety Air Gun and properly sized Shield. If you would like the same gun with a 12″ extension you would order as such; 1210-12-CS and you will receive the Model 1210 VariBlast SAG with a 12″ Aluminum extension and Chip Shield.

If you have a SAG with an extension pipe and want to add or replace a Chip Shield then we must consider the extension pipe and nozzle NPT. All of the Chip Shields are the same size with the exception of the center diameter and the rubber grommet which will accommodate the NPT size of the Air Nozzle and extension. Here is a list of the replacement shields:

If you have a SAG and do not have an extension pipe or shield we have Chip Shield Kits that will allow you to retrofit your existing gun:

One important note is that SAG’s that are equipped with a Stay Set Hose will not allow for the Chip Shield to be installed. Choosing the correct Chip Shield or Retrofit Kit can be tricky but EXAIR Application Engineers are always ready to help.

Industrial Housekeeping Overview: The Vac-u-Guns

Manufacturing product can be a very dirty process that can generate large amounts of biproduct, trash, and loose material that is lying around or has been spilled. Especially when it comes to spilled material you might not want get rid of the material because it is still good. Well, EXAIR has the solution for you! Introducing the Vac-U-Gun systems! The Vac-U-Gun system is just as it sounds; a hand-held vacuum cleaner that can be turned on and off by simply pulling back the trigger. This system can allow one to easily clean up messes such as metal chips, plastic pellets, nuts, bolts, paper scraps, and much more. Altogether this gives you and easy way to keep your work space clean. Best of all the Vac-U-Gun isn’t just a vacuum system it can also work as a blower to blow air or transfer material.

EXAIR’s Vac-U-Gun System

The Vac-U-Gun system works off of the same principle of Entrainment as EXAIR’s Air Amplifiers and Line Vacs which can produce a strong suction for moving material. The removable generator located in the back of the Vac-U-Gun can be easily taken out and reoriented in order to create a strong blowing force that can be used for either blowing surfaces off or transferring material.

Vac-U-Gun Kits

The Vac-U-Gun can be purchased in three different kits to help get you started:

6192 – Collection System: Vac-U-gun, reusable bag, brush, crevice tool, skimmer tool, (2) extension wands

6292 – Transfer System: Vac-U-gun, 10’ Vacuum hose, brush, crevice tool, skimmer tool, (2) extension wands

6392 – All Purpose System: Vac-U-gun, 10’ Vacuum hose, reusable bag, brush, crevice tool, skimmer tool, (2) extension wands

If you have a blind hole that you just can’t seem to be able to clean out, then look no farther than the Deep Hole Vac-U-Gun. The Deep Hole Vac-U-Gun has all the same features as the Vac-U-Gun but adds a quick blast of air to dislodge anything in the holes so it can be vacuumed up.

The Soft Grip Super Air Scraper for Cleaning Tanks

A transport company was in the business of moving food product like powdered milk, sugar, salt, gluten, etc. to different Food and Beverage industries.  The tanks ranged from 1,700 to 2,200 cubic feet (47 to 61 cubic meters) in volume.  Because of condensation that can occur, some of the powdered materials would solidify on the sides of the tanks.  They found it occurring more often with the powdered milk.  So, they created a cleaning mechanism to use compressed air and an open pipe to clean the residue after each stop (reference above).  They realized quickly that with this type of cleaning nozzle was not safe and not efficient.  They could only scrape roughly 1” (25mm) at a time.  The noise level was too loud, the compressed air usage was too high, and the time to clean the tank was too long.  They contacted EXAIR to see if we could improve on their process.

Model 1144 Super Scraper Nozzle

The answer to the problem was the EXAIR 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 3” (76mm) wide 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 on the users.

Scrape off, and blow away, stubborn debris with the Model 1244-48 Soft Grip Super Air Scraper.

For the company above, this was the perfect tool to improve their process.  I recommended the model 1244-48 Soft Grip Super Air Scraper which had a great length to reach the tank areas and a foam grip to comfortably force the blade under the powder residue.  With the compressed air, it helped to keep the area clean during scraping and aided with the areas that were really stuck.  With the 1” (25mm) pipe as compared to the 3” (76mm) blade, the cleaning for each tank was cut in half the time.  Also, with the open pipe, they were using roughly 150 SCFM of compressed air.  The model 1244-48 was able to cut this amount down to 22 SCFM at 80 PSIG.  This was a huge cost savings.  And as a bonus, the noise level was lessened from 100 dBA to 77 dBA; a much safer way to protect any hearing damage.

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

Video Blog: Laminar and Turbulent Flows

I have written blogs about laminar and turbulent flows as related to the Reynold’s number.  Now, let’s demonstrate the difference between the two flows and the advantages of laminar flow from EXAIR’s engineered air nozzles; as demonstrated by our VariBlast Safety Air Gun.
