GENERAL DESCRIPTION:
The fans of the AL series find their principal application in the civil and industrial ventilation plants,heating and conditioning. They can convey clean air and light smoke with temperature of +100°C.
The series consists of different models with impeller diameter from 200 to 450 mm. All sizes are available with discharge angle adjustable by every 45°, with the exclusion of 180° and 225° orientation, which require a special construction.

CONSTRUCTION:
• Volute casing in folded steel sheet, protected against atmospheric agent by epoxy paint.
• Single inlet, single width, forward curved impeller (sirocco type), manufactured in galvanized steel sheet from type 200 to 315 and in steel sheet with welded blades epoxy painted from type 355 to 450.
• Execution 4 (with impeller directly coupled to motor with feet).
• Standard orientation LG 270°.
• Asynchronous three-phase or single-phase motors according to international standards IEC 60034, IEC 60072, EMC 2004/108/CE, LVD 2006/95/CE, CE marked, IP 55, class F. ACCESSORIES
• Inlet and outlet protection guard manufactured according to UNI 12499 norm and protected against the atmospheric agents.
• Round inlet cone, in steel sheet epoxy coated.
• Round inlet adaptor.

UPON REQUEST:
• RD rotation ATEX version according to Directives 94/9/CE and 2014/34/UE. See Catalogue 2 ATEX Range.

INSTALLATION:
The centrifugal fans with forward curved impellers must always be installed to ducted systems, eventually with the use of additional resistance (for example setting shutters), that can limit the air flow in such a way that the absorbed current is within the acceptable values stated on the motor rating label.
