Our possible combinations of blade profile, impeller diameter and material, hub design and size produce a choice of many thousands of configurations. In addition, we can design Variax® fans for vertical as well as horizontal alignments, and turn the inlet box to suit particular installations. Specific challenges, such as the complex C-position fans required for flue gases with temperatures close to the acid dew point, are well within our experience.
Designed for pressures of 300 Pa/1 to 15,000 Pa/120 InWG at volumes between 25m3 and 1600m3 per second /50,000 ACFM and 3,400,000 ACFM.
Designed for pressures of 1500 Pa/6 InWG to 30,000 Pa/120 InWG at volumes between 15m3 and 1600m3 per second /32,000 ACFM and 3,400,000 ACFM. In two-stage VARIAX® fans, the inlet box is also mounted on rollers and tracks to allow access to the first stage impeller unit while the moving diffuser gives access to the second stage.
