Curtain Transvectors
Air Knives Deliver Flat Sheet of Amplified Air
ITW Vortec Curtain Transvector® Air Knives
efficiently blowoff wide surfaces of debris as well
as provide high speed drying or cooling for a
broad range of industrial applications. Ionizing
Curtain Transvectors® add a Static Neutralizing
Bar to kill static cling and discharge dust and
particles for blowoff.
Since Curtain Transvectors® are air amplifiers, they use a small amount of
compressed air to deliver a powerful, high velocity, laminar sheet of air over
wide areas such as moving webs, film, sheets, strips, auto bodies and other large
assemblies and objects. Our patented design produces increased thrust and
velocity, reduced noise, excellent uniformity, and significantly outperforms any
competing, wide blowoff device. Stainless steel models are ideal for food,
pharmaceutical, chemical and other applications where purity, high
temperatures or corrosive environments are concerned.

More Compact and Affordable Than Electric Blowers

On an automated fabric cutting machine,
a problem-prone, retracting clamp bar was
replaced with two #921-24 Curtain
Transvectors. The maintenance free air knives
hold the fabric in position for slitting and
blow away any loose threads.
After testing many different products, a sheet
metal fabrication plant stamping oil pans for
automobile engines determined that a
#921-18 Curtain Transvector was ideal for
replacing their inefficient, drilled-pipe
blowoff. The patented air knife did a superior
job of stripping moisture and debris from the
pans, while reducing air consumption.
A German packaging company increased
production rates of their label printing
equipment by 34% when a #921-12 Curtain
Transvector was installed to speed ink drying.
Cooling parts emerging from a powder
coating oven had been the problem for a
metal finishing firm until they mounted #921-24
Curtain Transvectors on each side of the
product to quickly dissipate the heat.

Curtain Transvectors®, as well as
the Ionizing versions, have
numerous and diverse processing,
finishing, fabrication, assembly, and
other industrial uses for cooling,
drying, cleaning or static removal
on wide surfaces, including:
