EVOLUTION
Half the Weight, Twice the Performance - Watch The Video
When designing a new
product, we look at how our product can help our
customers perform better and be more efficient.
When looking at wands, we found that certain
wands increased the performance of our machines
while others decreased performance. By
retesting our portable extractors at CRI using
the Evolution, all of our heated portables of
300 psi and above went from a bronze rating to
GOLD, making U.S. Products portable extractors
the first and only to achieve this top Gold
rating.
The Evolution carpet wand from
U.S. Products was designed by understanding the
theory of air flow. Air flows from a region of
high pressure to one of low pressure. When air
flows at higher velocities, especially through
an airway with irregular walls, flow is
generally disorganized, even chaotic, and tends
to form eddies. This is called turbulent flow
(See Diagram 1). This is the type of air flow
found in most carpet wand designs today. A
relatively large driving pressure is required to
sustain turbulent flow. To double the flow rate
when you have turbulent flow, you must quadruple
the driving pressure.
When flow is low velocity and
through narrow tubes, it tends to be more
orderly and streamlined and to flow in a
straight line. This type of flow is called
laminar flow (See Diagram 2). Unlike turbulent
flow, to double the flow rate with laminar flow,
one need only double the driving pressure.
The Evolution is the first and
the only rotationally molded carpet wand on the
market that utilizes the benefits of laminar air
flow. By smoothing the air flow, we have
dramatically increased air flow, thus improving
water recovery performance.
Through scientific testing
against many other traditional wands, we have
found that the Evolution left half the residual
moisture in the carpet that the best performing
wand in the test group removed. Watch the
video for more details on the testing procedure.
