Centrifugal fans for medium-high pressures and medium flow rates.

Diameter of the impeller: from 310 to 900 mm

Backward curved blade series of fans manufactured to obtain medium-high pressures with medium flow rates, high performances and moderate noise levels.
ARL series is particularly suitable for clean and dusty air suction and can be used for pneumatic conveyance of solid-granular material (but not filamentous), finding use mostly in industry also for flue gas and noxious gases.

Working fluid temperature can go up to + 80°C for standard execution and up to + 200°C for SV execution. Higher temperatures can be reached with suitable changes in standard product.
The impeller, in welded steel sheet, is manufactured with backward curved blades and with a conical impeller shroud, expressly shaped to assure a good coupling with inlet cone.

ARL standard series fans are manufactured in arrangement 4, equipped with a motor support base. The installed motors are in B3/B5 construction, 2 poles, enclosed selfventilated and standardized UNEL MEC ip55 clF.
