 Offset Your Air Pressure Needs
The PowerStar 4B gas booster used the differential
piston area principle to operate. It features low air consumption,
quiet operation,
optional mechanical separation, and compatibility with a wide range
of common gases.
The PowerStar 4B booster is a reciprocating,
single or double acting or dual stage air operated design, using
an air-piloted
unbalanced type air directional valve to cycle the booster.
It is designed to make optimum use of commercially bottled
gases as low as 50 psi. The booster is applicalbe across a
variety of industries including aerospace, automotive, chemical,
fire protection, agriculture, fluid power, machine tool, plastics,
and packaging.
The Principles of Operation
The PowerStar™4B gas booster operates on the differential
piston area principle. A large area piston, driven at low air
pressures, drives a small area compression piston which
converts input gas to higher pressure. The output gas or discharge
pressure is determined by the ratio between the area of
the drive piston, the operating air pressure and the available
precharge pressure supply.
The function of the precharge pressure is to charge the high
pressure cylinder inside the booster with gas, reducing the
time needed to reach higher pressures. In double-ended gas
boosters, the precharge gas adds power to the compression
stroke.
The Actual Operation
The PowerStar™4B gas booster works rapidly at first,
then
slows and stops at a pressure balance. The booster holds the
pressure balance indefinitely, assuming no leakage. When a
pressure imbalance occurs, the booster automatically restarts
and restores the pressure balance. During operation, exhaust
air from the air drive section cools the high pressure boosting
chamber.
The Gas Booster in Action
Whether you use gas above normal cylinder pressure or require
continuous high pressure and want to get the most out of
the cylinder's gas supply, the PowerStar™4B Series is for
you! It
assures the optimum use of commercially-bottled gas. Some
units draw a vacuum.
