The Standard
GUINAULT-LEBRUN, have been specialists in 400Hz electrical aircraft
generators since 1949, and developed its first pneumatic start-up compressor
in 1968, based on an internally developed pneumatic regulator. Ever since,
GUINAULT-LEBRUN has established itself as the market leader thanks to
components selected for their durability and reliability, combined with a
great experience in aircraft start-up. In 2000, GUINAULT-LEBRUN developed
a unique concept: of electronic and automatic control of the air flow by
regulating speed between 1300 and 2000 rpm, producing reliability, fuel
economy, and lower sound emission. Today, the GUINAULT-LEBRUN ASU (Air
Start Unit) range covers all jet powered Regional and Commercial aircraft up
to an air flow of 400 Lbs/min.

The Standard
GS
GUINAULT-LEBRUN GPU
The ASU requires high reliability in order to avoid AOG (Aircraft on Ground) in case of failure of an
APU (Auxiliary Power Unit). It must be able, at any time and for any type of aircraft, to provide the
necessary compressed air (42PSI of pressure) to run the turbines and perform the start-up. It is
for this reason that GUINAULT-LEBRUN designed the safest ASU in the world using components
known for their reliability, such as Deutz and MTU engines, coupled with GHH Rand screw
compressors. The use of electronic regulation allows them to operate in the best conditions and
thus improve their lifespan, to limit noise at airports, and significantly reduce fuel consumption.
Purpose
of our GS units
Controlled risks
Drastically reduce the risk of AOG
Reduce costs by covering a wide range of aircraft with just one model
Fuel savings compared with traditional technologies
Provide very low maintenance costs (diesel engine)
Extend the lifespan of the product by an optimized operation (variable speed) Reduce the level of noise on the
tarmac (by reducing engine speed)
Extend the lifespan by the use of proprietary regulation technology (elimination of the risk of obsolescence of spare

Sturdiness and
Reliability
All components are of industrial design and selected for their endurance and strength. DEUTZ
engines and GHH Rand compressors are made in Germany and specially calibrated for this
function.
The electronics cards are designed and produced by GUINAULT-LEBRUN with the purpose of
limiting the risk of obsolescence and to control technology. The cards are designed in order
to withstand the most extreme conditions of temperature and humidity. The frame is hot-dip
galvanized, while the fuel tanks are plastic in and corrosion free.
The electronic control system contains no conventional mechanical air regulators, which are
more likely to fail.
Optimized
Design
Particular attention is paid to evacuating the heat generated by the machine, in particular, its
diesel engine and its compressor. The hot and cold air flows are partitioned, ensuring good
performance in extreme conditions with , repeat start-ups in a very hot environment. The
engine air intake is very large and high-frequency noise from the compressor is absorbed
at the source (intake), and before leaving the lines of the machine, thus avoiding the use of
soundproofing materials (foam), reducing air passages, and clogging the heat exchangers.
Ease
of use
The on-ground operation of the machine by the operator is extremely easy. Fully automatic
operation allows the user to focus on the security of the surroundings. The machine operates
at all times at its maximum efficiency without adjustment. Waiting periods that are at times
prolonged are run at minimum engine speed.
Electronic
control
GUINAULT-LEBRUN has applied its expertise in electronics to create a card that can adjust
the flow according to the needs of the aircraft, and the pressure depending on the mode
selected: Air Pack or Air Start. The electronic control allows, if necessary, to adapt the machine
to an unfamiliar start-up mode, different as may be found on new aircraft, as the operation is
not fixed by inflexible mechanical concepts.
Ease of
maintenance
Maintenance operations are limited to regular visual inspections and replacements of the
engine and compressor filters. Access to major components is easy with wide doors on
each side of the GS. Each component can be removed and replaced without difficulty. The
absence of a turbine-type high speed engine and mechanical regulator significantly reduces
the cost of maintenance.
Other services
Factory inspection and commissioning inspection.
Training on-site or in factory with educational support.
