A large manufacturing company called looking for a better solution to control the thickness of a curing agent being applied to the outside of tubing used in the automotive industry. The tubing is formed in an extruder and travels through a liquid cooling chamber and then air dried. After the tubing is dried, it is sent to a spray chamber where the curing agent is applied to the exterior. On the exit side of the spray chamber, the customer had installed several flexible air lines placed around the perimeter of the tubing to blow air across the surface to help control the coating thickness. This worked somewhat but they were seeing an increase in the amount of rejected material as the air pattern was sporadic and uneven, which caused streaking and dry spots in certain areas of the tubing. They reviewed our web site and familiarized themselves with our Air Wipes but were unsure of the best design and size to fit their need so they reached out for assistance.
After further discussing the process, their tube O.D. sizes range from 3/8″ – 1/2″, making our 1″ Air Wipe the ideal solution. As far as the design, the Standard or Super Air Wipe, I recommended they use our Model # 2451 Super Air Wipe kit due to the aluminum construction and stainless steel wired braided hoses being able to withstand the potential temperature in the area of 200°F. The kit includes a filter separator to remove any water or contaminants in the supply and a pressure regulator which would allow them to control the flow and force of the exiting air, to help “dial” it in to fit the demand of the application.
EXAIR Air Wipes features a split design, which can easily be clamped around the material, to provide a 360° uniform airflow, perfect for treating the surface of round shapes, like extruded tubing. If you have an application where you are needing to dry, cool or clean the outside of a pipe, hose or cable, contact an application engineer for help making the best product selection.
From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.
Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.
Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.
Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.
To discuss your particular application or for help selecting the best product, contact an application engineer at 800-903-9247 for assistance.
There are many times we field calls from customers that fall directly in line with the intended use of one of our products. Such would be the case last week when a customer called looking for a more reliable way to spray a light coating of rust inhibitor on the inside of a small section of ductwork roughly 9″ in diameter. They were currently using a liquid only spray nozzle but were having trouble controlling the output flow, as well as the actual spray pattern. They were wasting a lot of the inhibitor as it was starting to “pool” in the bottom of the ductwork which would ultimately leak out onto the production floor and operator’s work area when the parts were prepared for shipment, also creating an unsafe work environment.
After discussing the application with the customer, I recommended our Model # AT1010SS Internal Mix 360° Hollow Circular Pattern Atomizing Nozzle. The circular spray pattern is the ideal solution when trying to coat the inside of a duct with rust preventative. The nozzle produces an even spray pattern up to 53″ in diameter with flows as much as 14.7 gallons per hour of liquid, depending on air and liquid supply pressures. Our Atomizing Nozzles also feature an adjustment valve to provide control of the flow rate as well. The 303ss construction is able to withstand corrosive environments and temperatures up to 400°F (204°C).
EXAIR offers a wide variety of Atomizing Nozzles that can be used to coat, rinse or cool a surface. They are also commonly used for dust suppression due to the wide coverage area they produce. For help selecting the correct Model # for your application, give us a call.
