AIR-AIR PRESSURE MULTIPLIER
(BOOSTER)
The air-air pressure multiplier, or booster, is an automatic
device that compresses air to give an outlet pressure that
is double the inlet pressure.
It is normally used to locally intensify the input pressure of
one or more actuators. As it is entirely pneumatic it can be
used when electric devices are not recommended.
The booster can be supplied with or without a pressure
regulator.
It is fitted with check valves that maintain the outlet pressure
even when the supply of compressed air is switched off.
This means it is necessary to interrupt the supply and relieve
the circuit before intervening on the device in any way.
It is advisable to install a tank after the booster to prevent
fluctuations in outlet pressure.

OPERATING LAYOUT
The pressure booster is comprised of a central body (with one 3-2
valve, one 5-2 valve and four check valves), two side liners and a
through rod on which two pistons are mounted.
The supply air is compressed alternately by the two pistons in one
of the two central chambers (B and C); the other central chamber
and one of the two side chambers (A and D) operate the pistons;
the external chamber, which is not involved in compression, is
relieved.
Air compressed at a ratio of 2:1 passes through a check valve that
maintains the output pressure even when compressed air is no
longer supplied.
The valves in the central body, which are operated by mechanical
pusher pistons, switch the function of the two pairs of chambers (A
and D, B and C) at each piston stroke.

The graphs refer to the filling of a 10-litre tank and show the ratio of outlet to inlet pressure (= p2:p1) as a function of time (sec).
The graphs are valid for any inlet pressure between 2 and 10 bar.
The following formula can be used to calculate the time t (sec) required to switch from pressure ratio 1 to pressure ratio 2 in a tank
of volume V (litres):
t = V (t2 – t1)
10
where t1 and t2 are the times shown on the x-axis, corresponding to ratios 1 and 2.
E.g.
1 = 0.4 =>
2 = 1.2 =>
t1 = 2.5 sec
t2 = 10 sec
The time required to switch from 1 to 2 with a 25-litre tank is:
t = 25 (10 –2.5) sec = 18.75 sec
