Super
Ion Air Knife™ |
|
 |
|
|
|
EXAIR's new Super Ion Air Knife removes static
electricity from plastics, webs, sheet stock and other product
surfaces where tearing, jamming or hazardous shocks are a problem.
The laminar sheet of air sweeps surfaces clean of static, particles,
dust and dirt. Production speeds, product quality and surface
cleanliness can improve dramatically.
The Super Ion Air Knife floods an area or
surface with static eliminating ions - up to 20 feet (6.1m)
away. A balanced airflow across its length will not cause misalignments
to critical surfaces such as webs. Force can be adjusted from
a "blast" to a "breeze". The Super Ion Air
Knife is electrically powered, is shockless and has no moving
parts. It also requires less than 5 SCFM of compressed air per
foot of length at 5 PSIG (142 SLPM per 30cm of length at 0.3
BAR). Sound level is surprisingly quiet at 50 dBA for most applications. |

Ionizing
bars are very ineffective without an air delivery system. When used
by itself, a bar must be mounted within an inch of the charged surface
to fully neutralize it. This close mounting is impossible when the
static is generated in confined areas of a machine. Ion coverage
is minimal on oddly configured parts or when high production speeds
are involved. |

- Air inlets provided on each end and bottom of the
Super Ion Air Knife.
- Shims
can be installed easily if additional hard-hitting velocity
is required.
- Primary
air does not impact any surface of the Air Knife
keeping the sound level low.
- Insertion
molded emitter points eliminate potential dirt accumulation
that could degrade performance or eventually short the ionizing
bar.
- Emitter
points are sharp, durable stainless steel.
- The
power cable is shielded and has integral grounding. The threaded
bayonet connector is fully assembled and ready to use.
- Super
Ion Air Knife Kits are available which include all components
necessary for operation.

The Model
7901 or 7907 Power Supply has a lighted power switch and (2) 5kV outlets |
Bumpers, car bodies and fascia are cleaned of
dust and fibers prior to painting. |
| The
right type of air delivery is critical. Blowers produce an uneven,
turbulent airstream that can cause the positive and negative ions
to recombine before hitting the charged material. They are large,
suffer mechanical wear and provide limited airflow control.
The compact Super Ion
Air Knife uses a small amount of compressed air to produce a balanced,
laminar sheet of air to carry the ions to the charged surface,
even when it is far away. Flow and force are easily controlled
and there are no moving parts to wear out.
