Though all Real Blow Products works on same Coanda principle each products has distinctive features and makes it suitable for wide range of application. User may choose the best product according to the requirement of work space.
What are Air Amplifying Devices?
Air Amplifying devices are such device which consumes very little compressed air for the higher volumetric output.
How that is achieved?
Air amplifying devices are designed and made to use an unutilized energy of compressed air. When compressed air is passed through small orifice it attains very high velocity, which in turn mobilizes high amount of atmospheric air. Such effect is known as "COANDA EFFECT".
Where it is used?
Such devices has numerous applications, where ever compressed air is used at least one of such device is useful. For example, blow off operations, cooling, conveying, extracting fumes and dust, vacuum cleaning and other countless applications. How compressed air can be used for conveying and vacuum cleaning?
As air amplifying devices mobilizes high amount of atmospheric air, it creates powerful vacuum on one end and high volume blow on another. Vacuum side can be used to pick up materials to convey. If such material is collected in suitable dust collection system with suitable porosity filter than it becomes vacuum cleaning system. Why air amplifying systems are superior to conventional systems?
There are many reasons, few of them are mentioned below:
It consumes very little air than total output.
It saves energy.
There is no maintenance since there is no moving part.
It can be used in hazardous area as there is no electricity at the point of application.
They are portable and can be installed within minimum time without shutdown of any process.
Pay back period of air amplifying devices is very small as it requires fraction of investment.
What is the quality of air required?
Just like any other compressed air operated devices, filtered air is recommended.
What is operating cost and maintenance?
Operating cost largely depends upon the application; say if you use Real Blow instead of 3.2 mm Dia. open pipe than it consumes almost 1/4th of the compressed air than pipe nozzles still it delivers more than 6 times. So for the same given air flow one uses only 1/25 th of the compressed air. And maintenance, all air amplifying devices are virtually maintenance free as there is no moving part. How long it can convey?
Depending upon application, type of material conveyed, distance may vary, usually for lighter materials like powders and plastic pallets, 5 mtr. is the safe distance. Greater distance can be achieved by putting multiple units in series.
What will happen to my system if I pick up wet material?
Nothing, as there is no moving part or electricity. It may require frequent cleaning. Please note that air amplifying devices are self cleaning to an extent. What all materials it can convey? It can convey materials which are not having low flesh point and non volatile. From powder to granules to food grains to processed food powders to paper trims to wood saw to plastic parts to even nuts and bolts. Can it be used in hazardous and RF sensitive areas? Air amplifiers are the best possible answer for such areas, as there is no electricity at the point of application so no spark, no RF interference. How do I control suction and discharge?
Just by regulating air pressure you can achieve infinite control over suction or delivery. Unlike multispeed motors they are stepless. How do I choose right size for my material conveying?
Depending upon weight of the material to be conveyed per hour and diagonal size of the part. Choose throat diameter 1.5 times larger than largest part required to be conveyed.
