Profil (5)

Blade’s shape is slightly twisted. Therefore, it is possible to reach higher airflow parameters of fan and especially higher pressure increment in comparison with the blade profile (1HS).
Available diameters: 1250 – 20000 mm (4-66 ft)
Number of blades in impeller: 3 to 8 pcs.
Maximum tip peripheral speed: 75 m/s.
 
Special execution:
HT – for high temperature conditions: +120°C,
KO – acid resistant,
R – reinforced execution, for harsh operation conditions,
SE – stainless steel blade edge protection – for tip peripheral speed over 62 m/s or on demand,
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
