Air Amplifier or Air Movers From Nex Flow™

Air Amplifier,Air Movers,Air,Amplifier,MoversAir amplifier or "air movers" from Nex Flow™ Air Products Corp., are a simple, inexpensive devices with virtually no maintenance that can convey fumes, smoke, lightweight materials and move a high volume of air for cooling, blowoff and drying applications. They use the "coanda effect" which entrains a large amount of surrounding air using only a small amount od compressed air. The effect is an amplification of up to 17 times the airflow or more (depending on the size) with reduced noise levels. Using only compressed air, the output flow and vacumm is easily controlled by adjusting or opening the air gap and/or inlet pressure. Either end of the air amplifier may be ducted to address all kinds of applications from bringing in fresh air into an area to removing nasty fumes. Be wary of unrealistic or unsubstantiated amplification ratios claimed by some companies.

Air Amplifier Features:

  • No moving parts

  • More compact, simple, lightweight and portable

  • Driven by air, not electricity

  • Replace fans, used for blow-off, cleaning, drying, cooling and conveying

Air Amplifier Benefits:

  • Longer life in difficult environments than competative models
  • Lower compressed air consumption than ejectors or venturi
  • Maintenance free with output easily controlled
  • Safe to use

Air Amplifier Advantages Over Fans:

  • Compact design, simple, lightweight and portable
  • Driven by air, not electricity for safety
  • No moving parts, safer and maintenance free
  • Each end can be dusted for light conveying applications

Air Amplifier Types:

Air Amplifier,Air Movers,Air,Amplifier,MoversStandard "Fixed Air" Amplifier is made of a zinc die cast system and is solid and performs as well or better than many supposedly patented designs when used in similiar applications. The gap can be adjusted by using shims. Five sizes are available.
Air Amplifier,Air Movers,Air,Amplifier,MoversAdjustable Air Amplifier is made of anodized aluminum or stainless steel for high temperature or food applications. The customer can set the gap and lock it in place using a lock ring. Three sizes are available.

Air Amplifier - How It Works

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.

  • Made of Zinc alloy for strength and light weight.
  • Longer life in difficult environments than competitive models
  • High airflow amplification.
  • Lower compressed air consumption than ejectors and venturis.
  • Instant on-off, no moving parts, no electricity or explosion hazard.
  • Maintenance free with output easily controlled, safe to use.

Air Amplifier Applications

Replace fans, used for blow-off, cleaning, drying, cooling and conveying.

  • Automotive:
    Remove water, coolant, dust, and scrap in parts manufacturing/assembly operations. Cool enamel and water based paints in parts manufacturing, auto body shops or assembly lines.
  • Bottling:
    Blow off of water from the tops of cans, bottles prior to labeling, ink jetting, palletizing or packaging. Conveying light materials.
  • Chemicals:
    Blow off of chemicals or water prior to labeling or packaging.
  • Food:
    Remove water from product or packaging.
  • General Manufacturing:
    Part ejection, fume removal, dust and liquid blow off from all types of parts, conveying away waste, ideal for replacing fans in some cooling operations such as tempering glass.
  • Metals:
    Coolant and other liquid removal on process lines from Aluminum, Steel, Brass or other materials. Dry metals prior to other operations such as plating or polishing. Cool metal parts prior to coating or painting. Coolant mist removal. Boost vacuum systems to remove grinding dust. Cool steel forgings.
  • Paper & Lumber:
    Sawdust removal and control by boosting the vacuum system, dust removal. Trim removal in converting applications.
  • Plastic:
    Dust and scrap blow off. Cool moldings after extrusion, then blow off and dry prior to forming.
  • Printing:
    Cooling to set some inks, scrap blow off.
  • Pharmaceutical:
    Remove liquid prior to labeling or packaging waste removal for solid materials. Extract unfilled capsules by vacuum as they pass on a conveyor.
  • Textile:
    Scrap and trim removal on textiles to eliminate expensive vacuum systems.
