Adjustable Air Amplifiers - Gauged

The Nex Flow Adjustable Air Amplifier with gauged markings are used for a variety of applications. These are available in anodized aluminum and marked accurately to set the gap from 0 to 1.5 mm.

These adjustable air amplifiers can be mounted and maintained easily which means that compressed air consumption and noise levels are reduced. It takes energy from a small volume of compressed air to produce high velocity and high volume as well as low-pressure output airflow. This adjustable air amplifier is quiet, efficient and can amplify flows up to 16 times of the input air consumption rate.

Air Booster and Air Pressure Amplifiers:
An Air Amplifier is an Air Booster. They convert pressure to flow and are “flow” amplifiers. They are NOT Air Pressure Amplifiers.

Dust Collection System and Vent Smoke and Fumes:
Air amplifiers have been used as a dust collection system and to vent smoke and fumes from all types of equipment.

Dry Air Coolers:
Air amplifiers can be used as dry air coolers by blowing amplified airflow onto tubes of hot gas (normally air) to cool them.

Part Ejection System and Chip Removal System and Part Drying System:
Air Jets and Air Nozzles are excellent as a Part Ejection System, Chip Removal System and as a Part Drying System when air knives or amplifiers are not suitable.


Specifications

Constructed of anodized aluminum with two standard outlets (outside) diameters: 1-1/4" (31mm), 2" (51mm)
Come standard with a .002" (.05mm) gap. If greater air force is required, the gap is adjustable from 0 to1.5mm and easily set using the markings on the air amplifier and held in place after setting with a lock ring.

How Adjustable Air Amplifiers Work


Adjustable Air Amplifier
Adjustable Air Amplifier – A large volume of surrounding air is induced into the amplifier at point (A) by the action of a small amount of compressed air which enters the annular chamber at point (B) that is then throttled through a small ring nozzle at high velocity and into the inside of the amplifier over a coanda profile.   The compressed air stream clings to the coanda profile as it enters the inside walls of the amplifier creating a vacuum that induces the outside air converting the pressure into amplified airflow.  The amplified airflow leaves at the exit at point (C).   Airflow is further amplified downstream at point (D) by entraining additional air from the surroundings at the exit.

Adjustable Air Amplifier Ducting:

Both the inlet (vacuum intake) and discharge ends may be ducted for light material and fume conveying applications. Care must be taken to avoid unnecessary restrictions that will cause back pressure or suction resistance that will reduce performance levels. Keep back pressure and resistance to under 2" of water column.
