Custom Super Air Amplifier

Published on by Jordan T ShouseLeave a comment

A customer called in looking to incorporate some more airflow to help materials flow properly through their processing line. This line included several legacy machines, so we had to get creative to fit something with in the system in place. It just so happened there were several 3/4″ FNPT ports in the sections where the increased air flow was needed!

So we came up with a 3/4″ Super Air Amplifier, 120020. But rather than the typical smooth OD outlet we extended it a bit and put a 3/4″ MNPT thread on the end! See it below next to a photo of the 120020.

Right side is a stock 120020, and to the left is the Custom 120020 with a 3/4″ MNPT threaded outlet!

EXAIR’s Super Air Amplifiers achieve air amplification ratios ranging from 12:1 on our smallest units and up to 25:1 for our 4” and 8” models. EXAIR’s Super Air Amplifiers utilize a patented shim design to maintain critical positioning of component parts. This allows a precise amount of compressed air to be released at exact intervals toward the center of the Super Air Amplifier. This creates a constant, high velocity outlet flow across the entire cross-sectional area. Free, ambient air is entrained through the unit, resulting in high amplification ratios. The balanced outlet airflow minimizes wind shear to produce sound levels far lower than other similar air movers.

Super Air Amplifiers are supplied with a .003” thick shim that is ideal for most applications. Flow and force can be increased by replacing the shim with a thicker .006” or .009” shim. The flow of air is also controlled by adjusting the input pressure supplied to the amplifier. Higher pressures increase both the force and flow, while lower pressures decrease both force and flow. All Super Air Amplifiers are available in kits that come with a shim set as well as a suitably sized pressure regulator and auto-drain filter.

EXAIR has a solution for you if you need to move A LOT of air, even if we need to customize it to fit perfectly in your application. Also, this custom product only took a few weeks to produce, so delivery times are still reasonable!  Reach out to an Application Engineer today if you have an application that you believe could be served with a low-cost, simple solution!

Air Amplifiers, Pressure vs Flow

Published on by Jordan T ShouseLeave a comment

At least once a week I get a call about our line of Super Air Amplifiers regarding increasing the air pressure on a compressed air system. Well, the Super Air Amplifiers are perfect at increasing the volume of air you exhaust into an application by increasing the output air flow through entrainment of ambient air along with the primary compressed stream! So, they will increase volume for exhausting to atmosphere, but they do not increase your compressed air system pressure for an application.

But, let’s break the two things down a little further!

EXAIR Super Air Amplifiers!

EXAIR Air Amplifiers are a low-cost way to move air, smoke, fumes and light materials. These Air Amplifiers use the Coanda effect to create a low pressure area which draws in surrounding air to efficiently deliver a high volume of air to a target. Using a small amount of compressed air as their source, Air Amplifiers are among the most efficient products within EXAIR’s entire product line. EXAIR Air Amplifiers will create output flows up to 25 times their air consumption rate and deliver it at a high velocity. The entrainment of outside air amplifies the total volume of air at the output, which also increases force, cooling ability and circulation.

Air Amplifiers use the Coanda Effect to generate high flow with low consumption.

EXAIR’s Air Amplifiers have no moving parts, assuring maintenance-free operation. Fine-tuning flow, vacuum and velocity are easily controlled by regulating the input pressure. For gross adjustment of air flow and vacuum an internal shim is used to increase or decrease the internal “air gap” that the compressed air flows through. Both the vacuum and discharge ends of the Air Amplifier can be ducted, making them ideal for drawing fresh air from another location, or moving smoke and fumes away from an application.

Pressure Boosters

When folks first call in about Air Amplifiers, they generally have in their mind the concept of a pressure booster. Pressure boosters, by comparison, are completely different and are typically more complex systems involving motors or air cylinders in conjunction with feedback and operation controls. Their main job is to increase a baseline pressure in a system to keep low pressure situations from occurring within high value systems or for an unusual case of a pneumatic application that requires pressure higher than the facility, system pressure. For example, in robotic spray booths, the robots and valves require 50 PSIG but if they drop below 20 PSIG, the system can damage itself. A pressure booster can be installed to keep lower pressure systems maintained at a higher pressure for application needs. The systems on which pressure boosters are used tend to be more “closed loop” where a static pressure can be maintained. If a dynamic (moving) higher pressure is required for an application, a booster air compressor intended only for that application may be used to keep the entire facility pressure from having to be raised only to accommodate the one application.

It is my genuine hope that the above explanation regarding EXAIR Air Amplifiers versus air pressure amplifiers (Boosters) is helpful. If you have questions regarding EXAIR Intelligent Air Products please contact myself or one of our Application Engineers as we are always ready to help.

Understanding EXAIR Air Amplifiers and Air Pressure Amplifiers

Adjustable Air Amplifier

I take many calls regarding Air Amplifiers but sometimes I get calls that confuse EXAIR Air Amplifiers with air pressure amplifiers. EXAIR’s Air Amplifiers and air pressure amplifiers are fundamentally different and have different purposes.

First, EXAIR’s Super Air Amplifiers and Adjustable Air Amplifiers increase air volume, not pressure. Air pressure amplifiers increase air pressure from typical system pressure of 80-130PSIG up to 5000 PSIG. Air pressure amplifiers are an excellent solution for applications that require higher air or nitrogen pressure such as increasing force for clamps or presses and pressure testing processes. They are also known as air boosters.

Air Amplifiers use the Coanda Effect to generate high flow with low consumption.
