Explaining The Use Of Air Amplifiers

Air amplifiers are an inexpensive way to move air, fumes and smoke, as well as other light materials. They are simple units that work by converting the compressed air pressure into amplified air flow. They use the principle behind the coanda effect to create a high output flow of air. The power source of air amplifiers is compressed air, and the units use a small amount of it to produce high velocity and high volume of air flow from the surrounding air. They are quiet and efficient converters that increase the output flow by 25 times the amount of air they consume.

Just like the advanced air knives used in a large number of industries, the air amplifiers also have no moving parts and are virtually maintenance free. The advanced air knives are devices that have many applications in industries, such as automotive, food processing, pharmaceuticals, paper and packaging industries, and many others. They are used for cleaning, cooling, drying, heating, and similar applications. Air knives are more efficient and cost effective when compared to using manual labor to do the required jobs.

Industries that use air knives also make use of air amplifiers in their operations. The flow and vacuum created in the air amplifier units can be easily controlled. By increasing or decreasing the air pressure, the outflow can be increased or decreased.

Air Amplifier Applications Cooling is one of the major applications of the air amplifiers. The high outflow and the velocity produced is ideally suited for cooling casts made from aluminum as well as from copper. The result is a reduction in the cycle time required for the cooling cycle.

Air amplifiers are also used for venting smoke, drying wet parts, distributing heat in molds and ovens, general ventilation of confined areas, cleaning of machined parts, and venting of fumes from the exhaust tanks.

 In the automotive industry, they are used for removing dust, water, and scrap from the processes. They help eliminate water from fruits and vegetables in the food processing industry. In addition, they have useful applications in the pharmaceutical, paper, plastic, and many other manufacturing industries as well.

Types Of Air Amplifiers

There are basically two types of air amplifiers, the standard air amplifier and the adjustable air amplifier.

These types are available in aluminum as well as in stainless steel. The adjustable air amplifiers can adjust the air gap considerably. They greatly reduce the levels of the noise as well as the consumption of the compressed air. This helps regulate the outflow and the consumption of the air.

The aluminum adjustable amplifier has a temperature rating of 275°F (135°C). The stainless steel adjustable amplifier has a temperature rating of 400°F (204°C). Both these devices have variable sound levels and are available in standard sizes varying from 1¼” to 4”. 

 The high temperature stainless steel (Type 316) adjustable amplifiers are also available for specific uses. They are perfect for corrosive applications and also come with variable sound levels. They have a temperature rating of 700°F (371°C) and are available in sizes varying from 1¼” to 2½”.
