About this part
Industrial centrifugal draft fan engineered for forced draft (FD) primary/secondary combustion air injection or induced draft (ID) flue gas extraction. Features a dynamically balanced backward-curved or radial-blade impeller, heavy-gauge steel scroll casing, and direct-drive or v-belt driven industrial motor designed to overcome high system resistance in boilers, economizers, and dust cyclones.
Key features
- Dynamically balanced impeller meeting ISO 1940 G2.5 vibration standards
- Heavy-gauge galvanized / carbon steel scroll housing with flanged outlet
- High static pressure delivery for fluid bed grates and cyclone ductwork
- Hardfaced wear-resistant impeller coatings available for abrasive ash duty
- Continuous duty TEFC industrial electric motor with variable frequency drive (VFD) compatibility
Typical applications and wear
Biomass fired boilers, coal boilers, oil/gas burner primary air, and bag filter dust collectors. Wear involves impeller blade erosion from flying ash and bearing mechanical fatigue.
Compliance
Essential for maintaining precise furnace negative draft and optimal air-fuel combustion ratios.
