1)
ELECTRIC MOTOR
The standard motors are asynchronous, three-phase, with B5 aluminium or cast iron casing, 2 poles, protec-
tion degree IP55, isolation class F, with the following voltages and frequencies (see modular key box 19). The
motors are constructed according to the
IEC-UNELMEC
standards.
The motors are manufactured in compliance with the
IEC-UNELMEC
standards and are
ATEX
certified in ac
-
cordance with standard ATEX Directive.
2)
PROPELLER
The impeller is manufactured from metal sheet. The casing ensures a perfect sealing against water infiltration.
The sealing between the motor and the impeller is ensured by a silicon gasket. The outlet is obtained, always
of sheet metal, a round or rectangular spout for the connection of fittings for the air release pipes. At this dis
-
charge it is possible to apply a slide for choking the air flow exceeding the required value (VPA).
3)
IMPELLER
The self-cleaning type impeller consists of two disks manufactured from sheet steel between which there lies
the welded paddles.
