Six decades of experience manufacturing air and gas blowers, compressors and exhausters that meet the highest demands required by the market.
For over 60 years MAPRO® prodices in Italy and sells all over the world various types of machines for the compression,
suction and vacuum of gaseous fluids such as air, biogas, methane and industrial gases, including corrosive ones. Our strengths are the large experience in the execution of special machines on Customer request and the assistance in the design phases to study the most technically reliable solution.
The MAPRO® centrifugal fans, MCF Series, are made of:
The compression of the gas occurs through the increment of kinetic energy given to the gas by the vanes of the impeller and the subsequent conversion of the kinetic energy into static pressure in the discharge volute.
The MAPRO® centrifugal fans, MCF Series, to be used for extraction or compression of combustible gases, such as biological or natural gas, have been designed in order to fall within the Equipment-Group II as defined by the 2014/34/EU Directive, Category 2 both for the surrounding area conditions and for the internals of the machine. Their main construction features are the following:
The centrifugal fans are generally coupled to the electric motor via belt drive and the safety drive guard is made of spark-free material. We can also offer machines coupled to the electric motor via flexible shaft coupling and centrifugal fans manufactured in the so-called “CLOSE COUPLED” version (MCF…CC type) – i.e. a flange mounted electric motor is bolted to the fan casing and the impeller, which is dynamically balanced, is fitted directly onto the motor shaft extension.
MAPRO® centrifugal fans, MCF series, can also be supplied for intake or compression of ambient air. In this case, their construction is simplified. For the air-handling version too, it’s available the execution for Zones 1 and 2, 21 and 22 of the 2014/34/EU ATEX European Directive.
The rotating parts are not in contact with the casing during rotation. There is therefore no friction during operation and thus no internal lubrication is necessary. The gas moving through the machine remains uncontaminated and completely oil-free.
The other main advantages of using the MAPRO® MCF centrifugal fans are:
