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.

EXAIR’s Sanitary Flange Line Vacs: An Overview

EXAIR’s Sanitary Flange Line Vac is the ideal solution for customers looking to convey bulk materials in food & pharmaceutical applications (among others). Operating in the same manner as EXAIR’s smooth and NPT threaded Line Vacs, the Sanitary Flange Line Vac is available in (4) common flange sizes: 1-1/2”, 2”, 2-1/2”, and 3”.  All of EXAIR’s Sanitary Flange Line Vacs are constructed of Type 316 Stainless Steel for superior corrosion resistance.

There are different styles of flanges in industry. The Sanitary Flange Line Vac has been designed according to the flange standard outlined in ISO 2852. This standard was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Sub-Committee SC 1, Steel tubes. This is the second edition that replaces the first edition (ISO 2852:1974). The standard specifies the dimensions, tolerances, surface roughness, materials, assembling, and the hygienic requirements for the flange. These styles of flange are intended to be used with stainless steel tubes, specified in ISO 2037. ISO 2852 is considered an international standard, defining the connections used for non-permanent food-grade piping systems used within the pharmaceutical, food processing, dairy and agricultural industries.

In these industries, it’s required for the components to be thoroughly cleaned and sanitized. Using this type of connector, components within the piping system can be easily removed, sanitized, and then reassembled. A lipped flange with a grooved indentation is on each end of the pipe or Line Vac. A sealing gasket is then placed in between each section of pipe. A raised groove on either end allows it to seat onto the mating end of each flange. A clamp is then placed on the outside, forcing the sections together and compressing the gasket, creating an air-tight seal.

If your processes currently utilize sanitary flange piping, EXAIR’s Sanitary Flange Line Vac is the ideal solution to help you convey bulk materials from one point to another quickly, safely, and efficiently. If you have interest to test one out in your process, EXAIR offers an Unconditional 30 Day Guarantee on all stock items. They’re on the shelf now available to ship same day with an order placed by 2:00 ET!

Sanitary Flange Line Vacs – Not Just for Sanitary Applications

When it comes to bulk material conveyance, it doesn’t get much easier than EXAIR Line Vacs. They’re on the shelf, in sizes from 3/8″ to 6″. All you need is the right length of Conveyance Hose and a supply of compressed air, and voila: instant conveyor system. Sizes up to 3″ can also come with NPT male threads, so you can pipe them up with PVC, black iron, or stainless steel piping, depending on the nature of the application.

EXAIR Line Vacs: For bulk material conveyance through lines from 3/8″ to 6″, in aluminum, 303SS, 316SS, or abrasion resistant hardened alloy, available from stock with the widest variety of connections in the industry.

When EXAIR introduced the Sanitary Flange Line Vacs, we figured the food & pharmaceutical markets would find a number of uses for them…and we were right:

  • A pharmaceutical plant that had been using a maintenance-intensive blower operated conveyor to move capsules from a fill press to a dryer installed a stainless steel piping system, fitted with sanitary flanges and a Model 161150-316 1-1/2″ Sanitary Flange Line Vac. The ease of installation and elimination of the heavy maintenance required by the blower system made the project a great success.
  • Another pharmaceutical plant uses the same Model 161150-316 to convey caps to the automated part of the system that places the caps onto the vials. This eliminated a concern with aluminum particulate contamination, which had specifically been an issue with other mechanical conveyor designs.
  • A machinery builder that specializes in food processing systems uses Model 161300-316 3″ Sanitary Flange Line Vacs to pull away casings from pepperoni rounds, prior to slicing & packaging. The casing scrap is conveyed to a waste receptacle. They also use Model 110006SS 6″ Stainless Steel Super Air Knives to blow the sliced casings into the Line Vacs’ suctions.

These Sanitary Flanges are compatible with stainless steel clamp pipe couplings that were developed to accommodate the stringent cleanliness requirements of the food and pharmaceutical industries. Also known as Tri-Clamp, Tri-Clover, S-clamp, 3A, and Sanitary fittings, they’re easily made & unmade for periodic maintenance. They’re designed specifically to limit areas where bacteria might grow (along the flanks of NPT threads, for example) so complete & thorough decontamination is more easily achieved.

These features have proven to be beneficial to other Line Vac users, too:

  • A chemical plant needed to convey long strands of cotton, 60 feet horizontally, to a scrap bin.  They designed a system with sanitary tubing because of the smooth, finished interior surface, which reduces the chances for the fine cotton strands to catch on imperfections on the inside walls of other types of conduit.  They installed a Model 161150-316 1-1/2” Sanitary Flange Line Vac, which easily conveys the scrap over that distance.
  • A bullet manufacturer uses Model 161200-316 2” Sanitary Flange Line Vacs to convey .22 caliber long rifle casings.  They use sanitary flange piping for ease of installation and because there are no sharp edges or burrs in the line, which could potentially mar the brass casings.

This is a small representation of a great number of challenges associated with bulk material conveyance that can be quickly, easily, and cost-effectively addressed by the use of EXAIR Air Operated Conveyors. If you have a potential application you’d like to discuss, give me a call.
