Add our customer service staff to that mix and you will experience orders that are shipped the same or next day (orders received by 2pm EXAIR time ship same day), with a fast and accurate order confirmation. EXAIR shipped products on-time 99.8% in 2021, and we continue that into 2022.

Our website and catalog include 16 problem solving product lines and thousands of products, technical data, photos and drawings to help you with your project. When reviewing our website or catalog, chances are you will find the answers to some of your industrial/production problems. Our catalog products are stock items, so in most cases we will process and ship orders the same day! Having the capability to get our products to your facility allows you to begin familiarizing yourself with our product(s) and perform trial(s). Since we manufacture these products locally, in Cincinnati, OH, we have the ability to make custom solutions if any of our stock products do not meet your needs.

EXAIR has competitive prices but you will also see cost savings from the efficiencies you realize with our Intelligent Compressed Air Products. Reducing your SCFM usage will decrease your energy cost. Our products also come with EXAIR’s 5 year Built to Last Warranty!

EXAIR leads the way in standards compliance by making certain our products meet the standards set forth by many organizations. You will see CE, RoHS, REACH, Conflict Mineral Free and OSHA compliance are common for our products. When considering safety, our products meet or exceed OSHA Standards 29 CFR-1910.95 (a) maximum allowable noise exposure and OSHA standard CFR 1910.22 (b) harmful dead end pressure.

Understanding Air Entrainment or Amplification Ratios and Air Knives

Super Air Knife has 40:1 Amplification Ratio, entrainment is illustrated as the curved blue arrows.

EXAIR’s Super Air Knife is the top performer among our engineered air knives and it dramatically reduces compressed air usage and noise when compared to other blow-off systems. The Super Air Knife delivers a uniform sheet of laminar airflow across the entire length of the air knife. Even at high pressure of 80 PSIG (5.5 BAR), the sound level is surprisingly quiet at 69 dBA for most applications.

One feature of the Super Air Knife is its Amplification Ratio, or the ratio of ambient air to compressed air within the forceful blast of air from the Super Air Knife. The design of the Super Air Knife entrains ambient air at an amplification ratio of 40:1 (ambient air to compressed air). Entrainment is defined in the simplest of terms as: to draw in and transport (something, such as solid particles or gas) by the flow of a fluid. The Super Air Knife design produces two low pressure areas where surrounding air is pulled into the primary compressed air stream and is delivered to your target. EXAIR’s Intelligent Compressed Air® products use the principle of entrainment to give you more air volume than just the compressed air being introduced from your air compressor.  This will maximize the force value for your application with the minimum amount of compressed air. Any pipe, manifold, or fitting can be modified to blow compressed air, however, these homemade blow offs will be very noisy and perform poorly when it comes to air entrainment, or amplification ratios. In contrast EXAIR’s intelligent compressed air solutions are engineered to be very quiet and use conservative amount’s of compressed air while maximizing the output volume through entrainment. 

Furthermore, the table below demonstrates the differences between blow-off systems and the efficiency of EXAIR’s Super Air Knife. You can see that the Super Air Knife outperforms all or most other options when comparing purchase price, sound level, maintenance, horsepower required and electrical costs.

The use of EXAIR’s Super Air knife not only save air consumption but you can notice the lower decibel rating which meets or exceeds OSHA Standard 29 CFR-1910.95(a) for maximum allowable noise exposure. If you have questions or need help with EXAIR’s Super Air Knife or any of our Intelligent Compressed Air Products please contact us and let us help you.

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: 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.
