Air Amplifiers
4.3
High-Pressure System
The HP pipes and accessories used must be matched to the air amplifier in terms of
pressure and cross-section. If this is not the case, the performance capacity and
safety of the air amplifier may be impaired.
4.3.1
Pressure pipe
The pressure pipe and corresponding accessories must withstand the air amplifier's
maximum outlet pressure. Only if a corresponding safety valve has been fitted to the
pressure pipe, is it permissible to fall below compressive strength. The cross-section
of the pressure pipe must not be smaller than that of the pressure port. A smaller
cross-section will cause a reduction in output capacity and increased warming of the
amplifier medium.
4.3.2
Amplifier medium
Air amplifiers are designed exclusively for use with compressed air. Other media
must be tested by MAXIMATOR GmbH in respect of their compatibility with the air
amplifier materials before being used.
4.4
Putting into Service
As with a standard piston compressor, the stroke frequency also causes pressure
pulsations in the air amplifier. You can reduce these pressure pulsations by
providing an additional volume (e.g. pressure tank). You can use a bypass pipe to
reduce the fill time of the additional volume downstream of the air amplifier. To
bypass the air amplifier, a pipe with non-return valve is branched off directly from the
compressed air port. The air amplifier does not start to increase pressure until
operating pressure p
b
is equal to the inlet pressure. Air amplifiers with an external
control air supply have a port marked "X" (also possible for SPLV 2 and GPLV 2).
This pipe, which is branched off from the inlet pressure, can be used for fitting a
pressure switch.
