Special applications: low-pressure installations
Cold water tank
Flow rates for low-pressure drinking water
Pressure range: 0.1 to 1.0 bar
In so-called low-pressure markets, the water
pressure depends on the gravity generated in the
building (gravity-fed system). The height of the
water tank placed above the appliance (e.g. the
faucet) determines the line pressure at the outlet.
Gravity-fed systems are characterised by low
pressure; a classic aerator does not achieve an
aerated stream under such circumstances.
Neoperl offers special models which create a soft,
comfortable, aerated water stream.
Flow rate V (full-flow model)
Aeration starting at just 0.2 bar (with a
minimum flow of 3.5 l/min). Flow rate V is
available for most aerator product lines.
Flow rate Q (low-flow model)
Aeration starting at just 0.1 bar with only
a flow of 1.8 l/min required. Compared to
flow rate V in the pressure range up to
0.6 bar, the Q has a lower flow rate and is
therefore the water-efficient variant of the V.
Flow rate Q is available for several aerator
PCA® V – the model for universal use
These days, pure low-pressure markets are
increasingly rare. Mixed systems with
pump-fed supply are becoming much more
common. Hence classic low-pressure and
standard-pressure applications may occur
side-by-side, posing a special challenge to
In order to do justice to both types, Neoperl
now offers the PCA® V aerator with DualCore® technology. This model creates a full,
aerated stream in low-pressure installations.
When the pressure goes up, its regulating
function maintains a virtually constant,
water-saving flow rate regardless of
