Standard (Fixed) Air Amplifiers

This Standard Air Amplifier from Nex Flow is meant for complex applications. It is easy to install. Maintenance generates compressed air consumption and reduces noise levels. The energy produces a small volume of condensed air for higher velocity and volume as well as low pressure output for air flow. This Air Amplifier functions quietly but surges up to 16 times the input of air consumption rate.

Features of the Air Amplifier include the following:

  • There are no moving parts.
  • You can look forward to a simple, compact, lightweight and portable design.
  • It is driven by air and not electricity.
  • It replaces fans used for blow-off, cleaning, drying, cooling and conveyance.
  • There is high airflow amplification.
  • There is an instant on-off function without any threats of electric shocks or explosions.
Benefits of the Air Amplifier are as follows:
  • It can thrive in difficult environments compared to other models.
  • Consumption of compressed air is lower than ejectors.
  • The amplifier is maintenance-free and safe to use. The output can be controlled easily.
The Air Amplifier has advantages over ordinary fans. Each end can be modified for light conveyance applications.

Specifications

Standard Air Amplifiers come in five standard outlet (outside) diameters: 3/4" (19mm), 1-1/4" (31mm), 2" (51mm), 4" (101mm), 8" (200mm).


Standard Air Amplifiers come standard with a .002" (.05mm) shim to control the compressed air exit gap which will work for 90% of all applications encountered. If greater force is required, more .002" (.05mm) shims or a .003" (.07mm) shim may be installed to open the gap for greater flow.

How Standard Air Amplifier Work


Standard Air Amplifier

Standard Air Amplifier - A small amount of compressed air enters the annular chamber at point (A) 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 and thereby creating a vacuum that induces the outside air at point (B) converting the pressure into amplified airflow. The amplified of 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.

Air mover Standard Air Amplifier - Ducting:

Both the inlet (vacuum intake) and discharge ends of the unit 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.
