 What
are Air Amplifiers?
A
simple, low cost way to move air, smoke, fumes, and light
materials. Air Amplifiers utilize the coanda effect, a basic
principle of fluidics, to create air motion in their surroundings.
Using a small amount of compressed air as their power source,
Air Amplifiers pull in large volumes of surrounding air
to produce high volume, high velocity outlet flows.
Quiet, efficient Air Amplifiers will create output flows
up to 25 times their consumption rate.
 Air
Amplifiers have no moving parts, assuring maintenance-free
operation. No electricity is required. Flow, vacuum and
velocity are easy to control. Outlet flows are easily increased
by opening the air gap. Supply air pressure can be regulated
to decrease outlet flow. 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.

How
Air Amplifiers Work
|
| Compressed
air flows through the inlet (1) into an annular chamber
(2). It is then throttled through a small ring nozzle
(3) at high velocity. This primary airstream adheres
to the coanda profile (4), which directs it toward the
outlet. A low pressure area is created at the center
(5) inducing a high volume flow of surrounding air into
the primary airstream. The combined flow of primary
and surrounding air exhausts from the Air Amplifier
in a high volume, high velocity flow. |

Due to the superior performance of the Super Air Amplifiers,
the old style "Standard Air Amplifiers"
are not shown on this website but are still available.

Special Air
Amplifiers
EXAIR
manufactures special Air Amplifiers suited to specific
application requirements. The special Air Amplifier
with grooved intake mounts to the suction tube of a
dust collector and is held in place with
set screws. The exhaust is easily ducted into
the existing dust collection system or can be directed
into a filter bag.
This
special Air Amplifier acts as a "booster"
for a maxed out dust collection system. The recessed
groove on the suction side allows secure mounting to
the existing dust collector intake tube.

The
Model 121021 High Temperature Air Amplifier (shown
on the right) was developed for moving hot air to
surfaces requiring uniform heating while in a furnace
or oven. Modeled after our Super Air Amplifier,
the High Temperature Air Amplifier is the most efficient
for pushing high volumes of hot air to points that typically
remain cool. This special design is rated for environments
up to 700°F (374°C) and its surface is protected from
heat stress by a mil spec. coating process (developed
for the aircraft industry), allowing easy disassembly
for changing shims or cleaning.

Another
stainless steel version for flange mounting was developed
as a fan back-up for exhausting flue gases from a
furnace. In the event of a power failure, this
special Air Amplifier can quickly evacuate the fumes
that could be harmful to workers close by.
This
special stainless steel flange mount Air Amplifier
was designed for exhausting hot flue gases from a
furnace.
