Profil (14)

Highly efficient, ultra silent blade designed for operation with low rotational speed.
Spatial shape enables to reach high airflow parameters. Currently, its the only blade on the market that is compatible with the most strict low noise requirements.
Available diameters: 1100 – 11000 mm (4-36 ft)
Number of blades in impeller: 3 to 5 pcs.
Maximum tip peripheral speed: 52 m/s.
 
Special execution:
HT – for high temperature conditions: +120°C,
KO – acid resistant,
R – reinforced execution, for harsh operation conditions,
SS – hub elements made of stainless steel SS304 or SS316,
SG – self extinguishing execution,
AS/SG – antistatic and self-extinguishing execution. Applied in ATEX zones. A certificate of ATEX directive compliance is issued for operation in zones II 2G, T1 – T6. In case of special execution, the above mentioned codes are at the end of impeller’s name, i.e.: WO 5940-5-(7) AS/SG/SE
