Generalities and construction
features in conformity with
the 94/9/EC Directive (ATEX)
The MAPRO® side channel blowers 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 94/9/EC Directive (ATEX), Category 2 both for the
surrounding area conditions and for the internals of the machines.
They are therefore gas-tight blowers, with the following construction
features:
casing and impellers made completely of spark proof
aluminium alloy;
casing impregnated with Loctite;
casing halves sealed;
shaft sealing by special double-lip seals which do not
require lubrication;
two-pole, type of protection d, flameproof electric motors,
with specific marking Ex II 2 G, additional marking Ex-d IIB T3.
The simplest solution for the manufacturing of the machines
is the so-called CLOSE COUPLED version i.e., a flange
mounted electric motor is bolted to the blower casing; the
impeller, which is dynamically balanced, is fitted directly
onto the motor shaft extension.
