WCF Small Size Boiler Centrifugal Fan

* Model WCF-2.0A~3.2A adopts high-temperature resistant structure & direct-coupled motor layout, specially designed for small boiler forced draft & induced draft, max allowable inlet medium temperature up to 200℃. ·

* High-temperature resistant coating on volute casing and heat insulation structure at motor junction effectively avoids high-temperature flue gas heat transfer to driving motor for long-time stable boiler operation. ·

* Fixed speed at 2800r/min, dual optional voltage (220V single-phase /380V three-phase) to match small boiler equipment power configuration of food, grain, chemical and heating furnace industry. ·

* Compact overall size is convenient for on-site installation matching mini steam boiler, hot air drying oven and CNC heating furnace supporting air supply. ·

* Optimized backward curved impeller improves combustion air supply efficiency and reduces boiler energy consumption.

WCF Model Features:

Material Properties

Featured by high temperature resistance, compact layout and stable air pressure output, WCF small boiler fans are widely used for air feeding & smoke exhaust of heating furnace, hot blast stove, CNC boiler, small steam boiler, drying equipment in food, grain processing and chemical industry. Standard unit is equipped with ordinary asynchronous motor; B-WCF explosion-proof variant fitted with YB flameproof motor is customized for boiler with flammable volatile fuel fume. F-WCF high-temperature stainless steel customized version is available for ultra-high temperature flue gas environment, keeping identical airflow parameters and installation dimension as standard carbon steel fan.

Benefits

Standard WCF fan conveys clean hot air or low-dust boiler flue gas; max working medium temperature ≤200℃, conveyed gas without sticky viscous heavy impurities and over-limit hard dust particles.

Fan Structure

B-WCF explosion-proof boiler fan retains consistent technical performance, outline dimension and foundation installation size with standard WCF fan, only driving motor is replaced with explosion-proof specification.

Model Selection

All models run at fixed 2800r/min with power ranging from 0.25kW~2.2kW, step-by-step power configuration covers full flow & full pressure range to satisfy different small boiler combustion air supply demand; detailed matching parameters are recorded in WCF official product manual.
