Backward Inclined Cabinet Centrifugal Fan
This series of fans has been specifically developed to complement ventilation, air purification, fire protection, and fume extraction systems in large-scale buildings such as shopping malls, sports stadiums, and exhibition centers. Featuring a compact design, superior performance, low noise, lightweight construction, elegant aesthetics, and easy maintenance, these fans can be customized with 16 different inlet and outlet angle options to meet diverse installation needs. Notably, the HTFC-V model—with its externally mounted motor—has successfully passed the 280°C high-temperature endurance test conducted by the National Fire Protection Quality Testing Center (GA211-2009), demonstrating continuous operation for over 60 minutes in extreme heat conditions. Additionally, this model can be retrofitted into an EX dⅡBT4-rated explosion-proof fan for hazardous environments.
The wind turbine manufacturing process has the following characteristics:
·Casing: Hot-dip galvanized steel sheet with interlocking seams, featuring no weld points, excellent oxidation resistance, and high strength.
· Impeller: Backward-curved double-impeller with a central disc structure, fabricated by high-quality carbon steel welding, and balanced to G5.6 dynamic balance standard (per JB/T 9101).
· Spindle: Precision-machined from high-quality bar stock, with a rust-resistant coating, and a maximum speed ≥ 1.25 times the highest operating speed.
·Cabinet Body: Cold-formed frame with galvanized sheet metal splicing design, offering a clean, aesthetically pleasing, and highly corrosion-resistant solution—plus it’s designed for easy on-site disassembly and assembly.
·Motor: A well-known domestic brand with reliable performance.
