The management and effective control to reducing or eliminating workplace hazards can be frustrating. Controlling the exposure(s) to occupational hazards is the fundamental method of protecting employees. The CDC published a useful guide called “Hierarchy of Controls” detailing 5 types of control methods as a means to implement effective control solutions.
The idea behind this hierarchy is that the control methods at the top of graphic are potentially more effective and protective than those at the bottom. Following this hierarchy normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.
Elimination and substitution, while most effective at reducing workplace hazards, also tend to be the most difficult to implement in an existing process. If the process is still in a development stage, elimination and substitution of hazards may be inexpensive and simple to implement. For an existing process, major changes in equipment and procedures may be required to eliminate a hazard.
Henri defined the Coanda Effect – the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops.
Henri-Marie Coanda (1885-1972) discovered the Coanda Effect in1930. He observed that a stream of air (fluid) emerging from a nozzle tends to follow a nearby curved surface, if the curvature of the surface or angle the surface makes with the stream is not too sharp. For example, if a stream of fluid is flowing along a solid surface which is curved slightly from the stream, the fluid will tend to follow the surface.
A number EXAIR products are designed to utilize the Coanda Effect and aid their performance. In some products, the Coanda Effect aids to create an amplification area where additional ambient air is drawn into the total airflow to increase total volume of air upon a target. This creates a more efficient and effective product. Also, since not as much compressed air is required, the noise levels decrease for products like EXAIR’s air knives, air nozzles, air jets and air amplifiers. EXAIR has been successful with positive impact for compressed air energy savings and noise reductions helping us meet or exceed OSHA Standard 29 CFR-1910.95 9(a) Maximum Allowable Noise Exposure.

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.
EXAIR products are used in countless applications across all facets of industry, we have been working to compile some in a easy to read Application Database on EXAIR.COM!
Today I wanted to cover a few application successes from within Foundries.
The first example is from a company who manufactures flux for aluminum processing. They were experiencing conveyor belt jam ups because not all the material would fall off at the tail end of the belt. What adhered to the belt would be carried over on the return, fell off due to gravity and vibration, and was causing build up underneath and jamming the belt. The Model 110036 36″ (914mm) Super Air Knife was installed on the end of the conveyor blowing off any tramp material as the belt came around the head pulley. This consolidated the debris to one area where they could easily reach it for removal. This all but eliminated maintenance and downtime.
A manufacturer of aluminum rods was having problems with removing drawing die lubricant from aluminum bar being cut to length. The lubricant was causing the bar to slip in the grippers, causing the bars to be cut short. Passing the bar through a Model 2402 2″ (51mm) Super Air Wipe effectively removed the lubricant, and eliminated grip slippage.
The last customer operates an aluminum foundry. A small actuating cylinder’s seals were failing frequently, due to the heat from a nearby furnace. Using a Model 3230 Medium Vortex Tube, they are able to direct a flow of cold air onto the cylinder, keeping the elastomer seals cool, which greatly extends their life.
If you have questions about any of the quiet EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
