GENERAL INFORMATION ON AERATORS
Stream patterns
Aerated stream
Aerators use the Venturi effect
to introduce air into the water
stream. This gives the water a
pleasantly abundant, soft feel
for the user – regardless of the
flow rate. Uncontrolled water
splashing is a thing of the past.
Laminar stream
Physicists use the term
“laminar” to refer to a stream
that flows in parallel layers with
no disruption between them.
The stream is crystal clear and
has a pure, natural appearance
– an interesting aspect for the
faucet designer. Furthermore, a
laminar stream is the ideal
choice for health care facilities
because of its hygienic advantages: aerosol generation is
reduced to a minimum due to
the lack of air intake.
Spray stream
The spray stream offers an ideal
means of dispersing water over
the largest possible wetting
area when the flow rate is low.
Its water-saving attributes also
make the spray stream an
interesting prospect for highly
frequented washrooms (e.g. in
public buildings).
Rain Spray stream
Neoperl's Rain Spray offers a
special washing experience.
Numerous little nozzles join
forces to produce an extensive,
abundant and pleasantly
effervescent stream of water – a
shower sensation for your
hands.
Lime build-up
Aerator testing:
Two new aerators have been tested in the following conditions:
– simulation of the equivalent of 5 to 6 years of use
– water temperature of approx. 15 °C / 59 °F
– room temperature of approx. 20 °C / 68 °F
– water hardness 20–30° dH (German hardness)
Aerators with metal wire mesh
screen
A film of water builds up over
time, which forms a bridge
between the insert and the
housing. This is where lime
begins to form. The lime
gradually spreads towards the
middle of the screen and finally
clogs the air inlets. The stream
becomes hard and splashes.

Aerators without metal wire
mesh screen
With full-plastic aerators, the
formation of water film bridges is
hindered. Lime build-up is slowed
down considerably thanks to their
unique structure (CASCADE® and
HONEYCOMB®). They continue to
produce a straight, non-splashing
stream of water, even after long
periods of use.
SLC Feature
Lime clogs aerators in time.
It forms more slowly on plastic
aerators than on aerators with
metal wire mesh screen.
Neoperl has developed the SLC
feature for maximum lime
resistance: you can simply rub
away any lime deposits on the
outlet surface of the aerator
with your finger.
