Why use energy-efficient and compressed air blowing products?

Nex Flow’s energy-efficient blowing products reduce noise and improve blowing, cooling and ventilation operations. The use of compressed air is most effective when “designed” appropriately following the laws of pneumatics. The most effective method involves the use of the “Coanda” effect, which inserts atmospheric air into the compressed air that escapes from a small “vacuum” or hole in the blowing product, so as to convert the pressure that is normally lost and noise into a usable flow. This has the additional effect of considerably reducing noise levels. Other ideas, such as the “Laval effect”, have been tried, but with poor results in performance and real noise reduction and energy savings. The “Coanda” effect remains the most reliable and effective way to improve the effectiveness of a blowing product, although it is not the only factor. Any turbulence must be reduced. As air moves in, out and around the blowing product, it affects its performance. An appropriately designed nozzle “converts” pressure into flow with minimal energy loss. This requires a balanced approach. By considering air movement and minimizing turbulence, it optimizes the ideal amount of inlet air for a particular application. When air comes out of a small “hole” in the blowing product, it is “atmospheric air” that is mixed with discharged air. Even if the airflow remains laminar for a long distance, the velocity will decrease. The blowing force that “hits” the target depends on both mass flow and velocity. There is a balance and a “range” within which flow and speed are most effective. If the incoming air is too much, the velocity will drop to a level where the blowing force is negligible. This provides a particularly interesting result relative to air nozzles and for the real effectiveness of “Air Conveyors,” or annular units called Air Amplifiers.

The main products for air amplification are air blades, air nozzles, air sprayers, air conveyors or air amplifiers, and air dryers. Air amplification technology is simple, lightweight, compact, low-cost, and easy to install and will offer immediate benefits on energy savings by reducing noise levels and improving your industrial environment.

Air amplifiers

Nex Flow air amplifiers are low-cost, maintenance-free devices. They are used to convey vapors, smoke, light materials and move a large amount of air for cooling, blowing and drying operations. Due to the “Coanda” effect to convey the surrounding air, they use small amounts of compressed air. They can amplify airflow up to 17 times (depending on size) with reduced noise levels.

Air Jets

Nex Flow Air Jetsare designed to reduce compressed air consumption and noise levels while maintaining a laminar flow with great blowing power. They channel large amounts of air from the surrounding environment through the sprayer (similar to air amplifiers) and are more efficient flow amplifiers than Air Nozzles.They emit a jet from the larger area than a Nozzle and are ideal for material removal.

Air Mag Air Nozzles

Nex Flow Air Mag Air Nozzle is a nozzle created with a unique, patented design to assist in the concentration of supply-generated compressed air and externally acquired air for a decisive laminar flow of air with the highest force per l/min in the market. This reduces both compressed air energy consumption and noise level compared with other sprayers and hoses.

Air Nozzles

The older designs of Nex Flow air nozzles are quite efficient in converting pressure into flow. In fact, like flow amplifiers, they are better suited for “cooling,” as they have a lower force/cubic meter ratio but a higher flow/cubic meter ratio than more sophisticated nozzles such as those in the Nex Flow Air Mag series.

Ring Blade Air Wipe Blowoff Systems

Ring Blade Nex Flow Air Dryeris a lightweight, compact and easy-to-use tool that produces a 360-degree jet of air around the object. It reduces the use of compressed air to save energy and greatly reduces noise levels. Such systems are essentially maintenance-free, and the jet can be easily controlled with a regulator.

Air Knives

Nex Flow Air Blade Systems use compressed air for industrial cooling and blowing operations. They are used intensively to replace sets of air nozzles, sprayers or perforated tubes to reduce energy. The Air Blades’ curtain airflow is an effective way to dry, clean, and cool. Energy reduction by air blades is between 30% and 90% depending on the application, and can have a noise reduction of 10 to 15 dBA and more.

Air Edger Flat Jet Nozzles

The Model 47011 Air Edger Flat Jet Air Jet is designed to provide a powerful source of laminar flow at high speed and force, to cool and blow where air blades are not powerful enough. Air blades are ideal for blowing away liquids and dust, but when heavier materials require more “force” to be moved, this product is what is needed for the job.

Manifold Mounted Systems

Multi-channel systems allow nozzles to be mounted in combination between two, four or six tools for blowing and cooling applications where air blades cannot be used and where some blowing power is required.

Safety Air Guns

Nex Flow safety air guns are durable, safe and convenient to use and incorporate our efficient air nozzles and jets to produce high-performance air and “laminar” flow, minimizing compressed air use and noise levels.
