Diameter of the impeller: from 450 to 900 mm
Radial blade series of fans manufactured to obtain high pressures with low flow rates.
HR series is particularly suitable for pneumatic conveyance mostly. These impellers can convey very dusty air or be crossed by granular material (but not filamentous).
This series finds use in joineries, industry of paper manufacturing, in tanneries, in textile industry.
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 radial blades, curved in inlet side with conical impeller shroud. This feature allows to obtain high performance and a very silent airflow also at maximum flow rates.
