Backward Inclined Blade Fans are units with radial impellers with backward curved blades. Fans are designed for nonexplosive and chemically nonaggressive air and gases. These units can be used for polluted air and light dusts but should not be used to exhaust solid parts. Fans are constructed of powder coated welded sheet iron. They have aluminium impellers which are mounted directly on the motor shaft. Oskar Air Products fans family can be matched with almost all our products. Correctly selected fan ensures that maximum air volume at maximum efficiency can be moved along the system.
