Fan impellers – quiet solutions
Profile (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 –adapter for working in high temperatures: up to +120°C,
KO – acid and alkali resistant,
R – reinforced execution,
SS – element of impeller’s hub made of SS304 or SS316 stainless steel,
SG – self-extinguishing execution,
AS/SG – antistatic and self-extinguishing execution. For impellers operating in ATEX zone. For impellers we provide certificate of conformity according to ATEX standard for operating in zone II 2G, T1-T6. In case of special execution above mentioned tags are visible on the enc of impellers name. For example: WO 5940-5-(7) AS/SG/SE
