BUSHR 5 RAH 200/300 A
Busch has introduced the first hygienically designed rotary vane vacuum pumps in the world: the RAH 200 A and RAH 300 A. They are members of the Busch R 5 family of rotary vane vacuum pumps, which has long been the established industry standard. More than 2.5 million R 5 vacuum pumps are in daily operation in many industries throughout the world.

RAH 200/300 A
Busch has introduced the first hygienically designed rotary vane vacuum pumps
in the world: the RAH 200 A and RAH 300 A. They are members of the Busch R 5
family of rotary vane vacuum pumps, which has long been the established industry
standard. More than 2.5 million R 5 vacuum pumps are in daily operation in many
industries throughout the world.
R 5 RAH models were developed
specifically for food packaging with tray sealers and thermoforming machines,
and are designed to be cleaned using steam jets and conventional detergents. The
unit surfaces are smooth and slightly inclined, allowing water and detergent to
drain away after cleaning to leave a residue-free finish.
pumps are water cooled, preventing heat emissions to the packaging machine and
cooled packaging area. The packaging area temperature (a legal requirement, and
important for food packaging operations) remains unaffected. In addition,
cooling energy is saved. A water cooled motor may be ordered as an option to
further reduce heat emissions.
The heat energy from the cooling system
can be reused elsewhere, resulting in an additional improvement to the energy
balance of the vacuum system. The water supply is easily connected to the
packaging machine cooling system. Installation is a simple process due to the
unit’s compact dimensions and flexible vacuum
Operationally reliable and
The rotary vane technology has been continuously
developed and optimised by Busch for 50 years, with constant focus on both
economy and reliability of operation. High efficiency and energy-efficient drive
units are the positive results of this development.
Busch rotary vane
vacuum pumps are fitted with highly durable carbon fibre composite rotor vanes
as standard equipment. These vanes were developed by Busch for the harsh
conditions encountered by R 5 vacuum pumps, and are manufactured inhouse
exclusively by Busch. Also specially developed are the highly efficient oil
separators, which guarantee the optimal removal of even the smallest of oil
particles from the exhaust air.
R 5 RAH – the only hygienic rotary vane vacuum pump for food packaging.
The rotary vane technology
enables a technically simple structure of the vacuum pumps. The consistently
high vacuum level in continuous operation is guaranteed through circulating oil
lubrication, perfectly coordinated materials and state-of-the-art and precise
manufacturing. The integrated oil separator ensures clean and oil-free exhaust
thanks to its sophisticated extractor system with integrated oil return. When
fitted with a gas ballast valve (optional), even large amounts of vapour can be
processed. A non-return valve in the inlet flange prevents air from flowing back
into the vacuum chamber when the vacuum pump is switched
off. Accessories/technical options
In addition to the
standard version with water cooled standard motor and heat exchanger, versions
with water cooling and encapsulated air cooled motor are also
